How to make a moped out of a bicycle. How to assemble a moped from a bicycle? & Nbsp

In conditions modern life everyone can provide themselves with personal motorized transport if they know how to make a moped from a bicycle.

Before considering how to turn a pedal horse into a moped, you need to clarify what this very moped is. This is vehicle, whose engine volume does not exceed 50 cubic centimeters. In theory, this transport develops a speed of no more than 50 km / h. Well, the very main difference from a motorcycle is that in the classic version the moped has a bicycle drive with a chain drive to the rear wheel. The movement begins in a bicycle way, and then the engine starts. In general terms, this is a moped. Now how to build it.

First of all, you need a motor. Nowadays it is very easy to get it. The market is full of petrol engines for brushcutters, chainsaws, and even motorized cultivators. The most compact and lightweight are, of course, the scythe and saw motors. However, not all of them are powerful enough. If you want to go without pedaling and with a breeze, then you need an engine with a power of two Horse power... If the engine still has less power, then you can use it. One of the advantages of compact motors for scythes and saws is that the gas tank is mounted directly on them, which in turn will save space and not have additional hoses.

In the simplest version, the engine is mounted above rear wheel using clamps. To do this, you need to make a base under the engine. It is made of steel (at least 3-4mm thick) by welding. The design depends on the design of the bike. After securing the motor, it must be connected to the wheel.

Rotation from the engine to the wheel can be transmitted either through a drive belt or through a chain. In the first case, you will have to mount a pulley on the wheel - install the rim bicycle wheel smaller diameter. In the second case, you will need to install a gear.

Now it's up to the little thing - to lead the gas to the bicycle handlebars. It's that simple. The only thing you need is a cable of sufficient length and a handle (you can use the same as for a manual bike brake). All this is easy to buy at any car shop, bicycle goods or find at a scrap metal collection point.

Of course, depending on the design features of the bike, some additional nuances may arise. We'll have to put hands and head. But for when everything is ready you will need an article "". Shurikens can be useful to you to fend off your friends chasing you with shouts of "let me ride".

And in this video you can see the finished version of such a self-made moped in action:

Naturally, over time, any cyclist wants to rest the leg muscles, and they think about equipping their favorite vehicle with a motor. Just pedaling is a thing of the past. If the cyclist is already old, going long distances without a motor is already inconvenient and uncomfortable.

When you ask the craftsmen why they need such transport, because you can just buy a scooter or moped, they answer that you can understand and feel all the joy of a home-made construction only in the process.

In addition, a moped or scooter would be inconvenient, for example, for a woman. And here everything is simple. A woman can easily saddle such a horse and go about her business.

Bicycle and chainsaw - where is the connection?

As mentioned above, a motor from a regular chainsaw is ideal for equipping a bicycle with it. How to assemble, install this unit on a bicycle, the manufacturer of which did not think about it in advance? Let's try to dot all the “i” s.

Optimum motor power

The chainsaw engine has a power of 1.5 horses. And it is not surprising that some cyclists think that such a weak motor will not even be able to move a bicycle larger from its place. For example, there are bicycles that weigh, together with a middle-aged man rider on them, almost 100 kg. It turns out that you shouldn't worry. And the engine from the chainsaw will master such a load. The bike will accelerate easily and calmly pick up a speed of 30-40 km / h, which is quite normal for a bicycle.

Overclocking

True, overclocking is not fast. Everything will happen rather slowly, but this will not interfere with a comfortable ride. In addition, the cyclist and his loved ones will not feel the nauseating smell of gasoline, and such a bike, as usual, can be safely stored in your apartment.

Noise

Some cyclists do not want to listen to the loud noise that the chainsaw engine makes, but there is nothing you can do about it. We'll have to come to terms with the characteristic crackling that the chainsaw makes and the noise while driving.

Motor mount

It will already be, rather not a bicycle with a chainsaw engine, but a real moped. The power unit will be mounted directly above the frame and secured under the saddle. It will turn out to be well and firmly fixed if you make a homemade clamp from any metal plate.

There is another option - to buy them ready-made. These clamps are equipped with perforations that adjust the height of the motor, but this is no longer so important.

Sleeve

Special washers and screws will be responsible for securing the bushing. The bushing itself is designed to tension the belt from the engine. Such bushings are different, or rather they have different diameters. It all depends on the wheel size of your bike. If the wheels are huge, then a 28-inch hub is purchased. Interestingly, there is a rubberized surface inside such bushings. How do you like this moped?

It must be remembered that the drive belt is also selected depending on the diameter of the bushing. In addition, it is important to know that the sleeve is always fastened evenly and without distortion.... V otherwise, there is no need to think about any normal operation of a bicycle with a motor from a chainsaw.

Throttle lever

The accelerator pedal is a lever in this case, which should be a moped of this type. A cable is responsible for controlling the lever, which regulates the angle of the flap. The lever is completely similar to that of a bicycle brake. This gives the advantage that it will be possible to throttle without turning the handle, as required by a moped, but simply by pressing on it, as required by chainsaws.

It is recommended to lead the lever cable to the bicycle brake control handle. You will have to get rid of the brakes themselves. In this case, they will be completely inappropriate, because given the low weight of such a vehicle, when you press the brakes at speed, the cyclist will certainly make a forward somersault and may damage himself.

On the other hand, bicycle motor sellers offer a special lever mounted on the handlebars, but here everyone decides depending on individual preferences.

As a result, by putting a motor from a chainsaw on a bicycle, we will get an excellent moped without spending a lot of money. Such transport will bring a lot of joy and pleasure, make it possible to maneuver well and go through the most difficult roads easily and simply.

And in this video you can see the finished version of such a self-made moped in action:

You should start by looking for a suitable motor. The heart of a chainsaw is suitable for this role. Use Friendship. Remember power. A homemade moped will not be able to move if the engine power is less than 2 liters. with.
To create a bike with a chainsaw motor with your own hands, you will need other components:

battery;
pulleys, gears;
transfer belt or chain;
drive cable;
clamps for fastening;
tools: screwdriver, pliers, etc.

The main place where the elements of the future unit will be placed is the bicycle frame. Here, the battery is mounted with fastening clamps on the upper pipe, the engine is mounted at the junction of the pipe passing under the saddle and the front lower pipe, next to the gas tank.

The next step in assembling a bicycle with an engine from a chainsaw is the manufacture of gear wheels-pulleys. With the help of these elements, the force generated by the motor is transferred to the rear wheel.

Use disc-sized outer stop casters to create the pulleys.

Do not forget about the strength and reliability of the fastening of the parts.

The assembly of the moped continues, we mount the assembled parts:

The front transmission unit is connected to the engine shaft.
We attach the second pulley to the rear wheel hub.
We put a belt on the transmission nodes. If using a chain, use gears instead of pulleys.

Having put the motor of the chainsaw on the bike, we proceed to the connection. We connect the working compartment of the engine with the battery, mount the ignition mechanism. An integral step in the assembly of a moped is a bundle of a handle for a brake and a motor. Adjust the tension of the connecting cable so that the engine can be easily started with the handle.

Ignition from a chainsaw to a motorcycle

Chainsaw parts are also used to modernize outdated vehicles or vehicles requiring repair, such as a motorcycle. A saw ignition system is often used to enhance this vehicle.

You will need:

flywheel;
flywheel spacer with key;
fan;
coil with high voltage wire;
aluminum plate for mounting the coil;
bolts, nuts.

Chainsaw ignition is suitable for motorcycles Ant, IZH Planet. Unlike magneto, such ignition is reliable and durable, not afraid of shaking and water.

For the correct assembly of a moped with your own hands, reliable service, for alteration and construction of other equipment, listen to the advice:

Before assembling the motorcycle, make sure that the main part - the bicycle - is in optimal technical condition. The modernization will increase the stress on all of its parts.
Check carefully the condition of the petrol tank. Fuel must not spill out as this could create a fire.
In addition to engine power, don't forget about volume and weight. The volume should not exceed 50 cm³, weight - no more than 6 kg.
When installing the belt, make sure that the part is firmly attached to the wheels, otherwise the accuracy of the impulse transmission from the motor to the wheel will decrease.
With the help of a chainsaw motor, you can independently design other equipment: go-karting or tricycle. You will have to make an effort: weld a strong metal frame, prepare a working gearbox.
With a sturdy frame, gearbox, driver's seat, at least 35cm wheels and a saw motor, try building an ATV.

Do not throw away old equipment parts. They can breathe a second life and create a comfortable means of transportation.

Option 1: how to quickly assemble a moped with a gasoline engine

Before you start creating a new moped from a bicycle, you need:

bike;
gasoline engine and gas tank;
battery;
pulleys or gears;
transfer belt or chain;
drive cable;
fastening clamps.

Recommended power - 2 HP with., and the volume of the engine should not exceed 50 cubic meters. see. A weaker engine will not allow you to move the bike; you will have to pedal for a while. An engine of sufficient power can be taken from an old moped. Other options are with a chainsaw or lawn mower.

The working unit of the engine, the gas tank and the battery are securely fixed to the frame using fastening clamps. Convenient location:

on the upper tube - battery;
the joint of the lower front and seatpost tubes - the engine;
next to the engine is a gasoline tank.

The next step is to make pulleys - special transmission units through which the engine power will be transmitted to the rear wheel. The starting material for the pulleys can be small wheels with external barriers, about the size of a CD. Prerequisites are material strength and reliable fastening.

Installing pulleys with your own hands on a bike:

The front gear wheel is attached to the motor shaft.
The second pulley is attached to the hub of the rear wheel of the bicycle.
A belt is put on the pulleys. The tension force is approximately the same as that of the chain. The belt must hold firmly to the wheels, it depends on how exactly the engine will transmit the force to the wheel.

If a chain drive is used instead of a belt drive, then instead of pulleys, gears are placed on the motor and wheel.

So, the transmission is ready, now we turn to connecting the engine:

The working motor housing is connected to the battery.
Assemble the "ignition" mechanism: an ordinary brake lever is attached to the steering wheel, then through a cable it is connected to the engine body.
Set the tension so that the motor starts freely through the handle.

Option 2: collecting a moped with a gasoline engine

This is an advanced method, and the result is more like a real moped. To make it, we need:

gasoline engine;
moped parts: wheels, shock absorbers, exhaust pipe, brakes;
proven bike frame;
instruments.

Since here we are already going to get a real moped, the frame must have increased strength and weight. Also, on mopeds, the frame design is slightly different, because of which it may have to be redone a little.

Wheels from a moped are put on the frame. The fork will need to be redesigned as the width of the wheels will be wider than the distance between the dropouts. Install shock absorbers on the fork if possible.

Carefully sort out the power unit of the moped and replace all defective parts. The propulsion system will require a separate space, for this a welded metal platform at the bottom of the frame would be a good option. The engine and fuel tank are secured to the site with metal mounts. It is better to place the battery closer to the steering wheel. An exhaust pipe is connected to the bottom of the engine. The pipe must be firmly fixed to the frame so that it does not dangle while driving.

Remove pedals and chainring from bicycle frame.
Install sprockets on the rear wheel from the moped and the engine shaft. A star on a wheel with a larger diameter.
Slide the rear wheel onto the frame.
Use a chain to connect the stars.

Motor connection. The clutch and throttle valve are connected to the ignition lever via drive cables. The tension is selected so that the engine can start immediately and start spinning the wheel.

Brakes. If only one brake can be enough for a bicycle (say, the front one), then here it is better to play it safe and install them on both wheels. The rear can be used as the main, and the front as an auxiliary, to adjust the speed.

In general, a homemade bike-based moped will look like this:

Since a vehicle equipped with an engine moves faster than a regular bicycle (for this, a redesign is thought), for safety reasons, it is necessary to put lighting devices on it. Personal protection items - helmet, knee pads and special footwear.

How to make an electric bike

If you have no desire to fool around with a gasoline engine, there is another option - to put an electric motor. It can be purchased or installed from another device. The first option for creating electric mopeds is preferable, since the required power is already provided in the engines.

Options for installing an electric drive on a bicycle - a motor-wheel and an independent engine on a chain or belt drive.

The motor-wheel differs from the usual one by the presence of a drive mechanism in the central part. With the help of wires, it is connected to the control unit. A significant advantage is the ability to make the bike front-wheel drive without making any changes to the classic transmission. And if you wish, you can even put two motor wheels. Installation is easy enough, provided the bike itself allows it. However, to moped bike with such wheels can be attributed with a big stretch.

It's a completely different matter - electric moped, that is, an analogue of the one discussed above. Of course, there will be no need for an exhaust pipe - this is a plus both in terms of reliability and overall weight.

Assembling an engine from scratch at home will be problematic, so we will consider how to put a ready-made shaft-motor.

Progress:

Install a new sprocket and a belt pulley on the carriage axle.
A shaft with a drive pulley is attached to the seat tube.
The pulleys are connected by a belt.
Through wires, the shaft is connected to a power source.
Pull the wires from the battery to the steering wheel switch.

The location of the battery is on the lower front tube of the frame or the trunk. Electric motor operation diagram:

When the electric motor is turned on, the rotating roller engages the rear wheel cover, pushing it.
The pulleys and the front sprocket transmit torque to the transmission.
A gear change will cause a change in output torque. In this case, the speed of rotation of the roller is kept constant.

DIY electric bike:

Additionally, a second shaft can be connected to front wheel by connecting it to the driven pulley of the main gear.

The engine allows you to reach the optimal speed faster and maintain it for longer. A bike-based moped is a budget option to own a faster and more powerful vehicle. In most cases, the transformation of a bicycle into a moped does not make irreversible changes in the design, therefore it is possible to return everything to its place.

As a child, every boy dreamed of installing an engine on his bike, today it has become much easier to do this. At the moment, there are ready-made solutions for such modifications, for example, you can buy a ready-made kit and it only remains to install it on a bicycle. Everything, after that the "great" will turn into a small moped, capable of traveling up to 50 km / h, or even more.

Such transport is beneficial for those who often travel to the dacha, fishing, to the village, to the garage, if it is far away. On such a bike-moped, fuel consumption will be minimal, probably there is no other transport that would consume even less fuel. In addition, even if you run out of gasoline, you can reach your destination in the classic way, using the pedals.

Another plus of this technique is that it does not require a driver's license, because in fact it is still a bicycle, because you can turn on the motor only outside the city.

Specifically, in this article, we will talk about how you can install a chainsaw engine on a bicycle. Many of them have unnecessary chainsaw motors or even entire old chainsaws lying around in the garage. A motor from a petrol cutter is also perfect for this purpose.

DIY materials and tools:

1. First you need an engine. The more powerful it is, the faster the bike will go. On average, today there are chainsaws with a capacity of 1.5-2 horsepower, this power is quite enough to drive a bicycle-moped at a speed of about 30-40 km / h.
2. Capacity for creating a gas tank. It is best, of course, that it be made of metal, so it will be safer. But you can also use plastic containers.
4. Bicycle cable and throttle grip.
5. Wires and switch for connecting the engine ignition.
6. Bolts, nuts, elements for creating a bracket with which the engine will be attached to the frame.
7. Pulleys, belts, chains and other elements through which the bicycle wheel will be connected to the engine.

The process of equipping a bike with a gasoline engine:

Step one. Determining the type of motion transmission
Perhaps the most difficult thing in this homemade product is to convey the movement from the motor to the wheel. It is important to correctly calculate the gear ratio. If the gear ratio is small, the motor may simply not pull that load and the bike will not run. If the gear ratio is too high, the bike will go very slowly, and the engine, working at high speeds, will overheat.

The gear ratio can be calculated using the example of one of the authors who managed to assemble a similar technique. With an engine power of 1.78 horsepower and 12,500 rpm, it used a gear ratio of 1:26. A Homelite CSP3314 model was used as a chainsaw.

The easiest way to transfer movement from the pulley to the wheel is directly from the motor, that is, according to the same principle as the dynamo works. If you approach the process more professionally, then the rear wheel is equipped with an additional sprocket or pulley, and then it is connected to the engine using a belt or chain. Of course, it is best to use a belt drive, since the chain with such homemade products can fly off, and in general it is unsafe.

Step two. Clutch
The grip is also very important element in this type of transport. There are two options for how you can do it. The chainsaw already has a centrifugal clutch, that is, it is a clutch that automatically engages at certain speeds. So the wheel can simply be connected to this clutch, this is the easiest option.

Some do-it-yourselfers do not use the saw clutch, but rather connect it to a bicycle ratchet. Such a system works very simply, after acceleration and release of the gas, the bicycle rolls by inertia, while the ratchet is not interconnected with the wheel. That is, "lawn" once, you can then roll for a very long time in a straight line at idle.

Step three. Installing the gas tank and connecting the control system
The gas tank can be installed right next to the engine, but for safety it is best placed on a frame. But in this case, you will need a hose that must be pulled along the frame to the engine.

As for the ignition, everything is simple here, you need to stretch the ignition wire from the engine, and make a switch on the handle so that the engine can be turned off if necessary.

Also, to control the engine, you need to make a throttle stick, you can borrow it from mountain bikes(buy ready-made). You need to remove the retainer from the handle so that it moves smoothly, and then connect the cable to the carburetor throttle.

That's all, after assembling the homemade product, you can start experimenting. Of course, it is important to check the brakes and additionally apply the front brake if one is not available. The engine starts in a classic way, with a kickstarter, like a chainsaw.

The only drawback of this technique is the sound of a chainsaw, which will scare passers-by. But if you try, this problem can also be solved by equipping the engine with a small muffler.

It would seem that absolutely incompatible things will not allow you to get a truly original invention, but in practice this assumption has already been refuted more than once. In particular, for those who do not know how to make a moped, having only a bicycle and a chainsaw from available tools, this article will be very informative.

Moped with gasoline engine

If you don't want to refuel the car every day, and riding a bike is too tiring, then a gasoline homemade moped will be the perfect solution to your problem.

What do we need

Nowadays, there are many ready-made kits that include an engine of the required power and other parts necessary for rebuilding a bicycle. Buying such a kit - great option for those who want to become the owner of a bicycle with a motor, but do not have the opportunity to make fasteners with their own hands or choose a suitable engine.

However, there are situations when, despite possible difficulties, I want to do all the work myself. In this case, it is worth starting with the choice of a suitable power unit, for the role of which one of the parts of the old and unnecessary household utensils may be suitable. A lawn mower or a chainsaw is the most suitable donor for a heart transplant, but do not forget about the power of each such unit. So, a homemade moped from a bicycle should be equipped with a 2 hp engine. and a volume not exceeding 50 cm3. A weaker motor will not be able to move the bike, and you will have to pedal for a while.

In addition to the powerplant, you will also need other parts: battery, pulleys and gears, transmission belt (you can replace it with a chain), drive cable and fastening clamps. Of the tools, screwdrivers, pliers, wire cutters and other components of an auto mechanic's kit will be useful.

We equip the frame

The bicycle frame becomes the main location for all parts and elements of a future moped. In particular, the engine, gas tank and battery are attached to it with the help of fastening clamps. The most successful option for their location is as follows:the battery is on the upper tube, the engine is at the junction of the lower front tube and seat tube, and the gas tank is directly next to the engine.

We make pulleys and install them

The next step on the path to creating a moped with your own hands is the manufacture of pulleys - special transmission units, through which the motor force will be transmitted to the rear wheel. As necessary materials small casters (about the size of a CD) can be used, complete with an external barrier. Required condition when creating pulleys, this is the strength of the parts used and the reliability of their fastening.

Installation of these parts on the bike is carried out in the following sequence:

1. The front gear wheel is connected to the engine shaft.

2. The second pulley is attached to the rear wheel hub of the bike.

3. Then a belt is put on the pulleys, setting the tension force, like a chain.

Motor connection

After the transmission is installed on the bike, you can proceed to connecting the power unit. For this, its working body is connected to the battery and the "ignition" mechanism is assembled. The motor mounted on the bike is associated with a brake lever, which is also an integral part of the do-it-yourself moped assembly. The tension of the connecting cable must be set so that the motor can start freely through the handle.

Assembling a moped with a gas engine

Compared with the previous version, this method will allow you to get a more "advanced" vehicle, which is almost completely consistent with a real moped.

What do we need

To accomplish this task you will need yourself Gas engine, spare parts from a real moped (wheels, shock absorbers, brakes and an exhaust pipe), a strong, welded bicycle frame and working tools (including a welding machine). Considering that in this version you are going to make from a bicycle real motorcycle, its frame must have adequate weight and strength. You can try to find a part from a small moped, but if it doesn’t work out, then a “skeleton” from a bicycle in the style of “Stork” or “Yew” will do.

Preparing the frame

Suppose you could not find a ready-made moped frame, which means you have to strengthen the bike. To do this, you need a welding machine and an additional pipe, which is welded onto the existing structure, thereby connecting the seat and the steering part. However, it must be said that this is not the only possible way to increase strength, and instead of a pipe, iron bars can be used.

By the way, the power plant requires a separate space, and the best option would be a welded metal platform located at the bottom of the bike frame. The engine and gas tank are attached to it with metal mounts. It is better to place the battery closer to the steering wheel, and connect the exhaust pipe to the bottom of the engine.

Create torque

The next step on the way to creating an electric bike with your own hands is the organization of the power unit torque transmission system. First you need to remove the pedals and chainring from the bike frame. Then sprockets are installed on the rear wheel from the moped and the motor shaft (the star is located on a wheel with a large diameter). After that, the rear wheel is put on the frame and the stars are connected with a chain.

We connect the engine

After completing all the above steps, it remains only to correctly connect the motor. To do this, the clutch and throttle valve must be connected to the ignition lever by means of drive cables. The tension force is selected so that the motor can start immediately and start spinning the wheel. As soon as you connect the power unit, consider that you have already succeeded in making a bike on a motor.

It is no secret that vehicles equipped with an engine will move faster than a regular bicycle, therefore, for safety reasons, it is worth installing lighting devices, and the driver himself must use a helmet, knee pads and special shoes. That's all. Another answer to the question "How to make a motorbike with your own hands?" I'm ready now.

Building an electric bike

If you don't like the idea of using a gasoline engine on your bike, then you can consider an alternative electrical upgrade to your vehicle.

Benefits of electrical equipment

The advent of modern electric vehicles has allowed humanity to appreciate all the advantages of this type of transport. An environmentally friendly and economical car almost immediately gained worldwide popularity, it is available to "tell" motorists about all the privileges of using electric motors. Therefore, it is not surprising that many people were interested in the question "how can you make an electric bike out of a bicycle?" The electric engine runs quieter, does not emit harmful exhaust gases into the atmosphere and does not heat up as much as its gasoline counterpart.

In the case of a home-made electric bike, the role of the engine can be played by a car starter, screwdriver, or any other power plants available on the farm. Along with the electric motor, an important component of the already converted vehicle is the controller (or regulator), the task of which is to accelerate the moped bike under optimal operating conditions of the power plant. To start the movement, a very small current flows from the controller to the motor, due to which the motor starts to rotate smoothly. In a braking situation, the regulator recovers the driving energy in electricity supplying the battery. The battery is practically the same fuel tank, but much more environmentally friendly. It often consists of a matrix and batteries connected to a specific circuit.

The simplest homemade e-bike includes only a motor and a battery. After installing the motor, it can be energized using a conventional switch. However, you should be aware of the impracticality of such an approach, because, having a powerful power plant, starting on such a vehicle is somewhat more difficult, and this can lead to an accident. It is better to use a low-power unit capable of providing a slow start to movement, even if it does not accelerate to serious values.

DIY chainsaw motorcycle

Not every lucky bike owner is delighted with the need to pedal and waste your energy. A motorized bicycle is more convenient and less expensive in terms of power.

A bicycle with a motor from a chainsaw with your own hands is not as difficult to make as it seems at first glance. For this you will need:

bike;
a saw with a gas engine power of at least 2000 W - it will depend on this indicator whether it can get under way. As practice shows, the engine power is 2 hp. it is enough for the motorbike to reach a speed of up to 40 km / h;
a tank for the future fuel tank;
cable from an old bike;
handle to be able to adjust the throttle;
bolt ties, nuts and other small consumables for creating fasteners;
connecting elements for creating a connection between the wheels and the engine.

The process of putting a chainsaw engine on a bicycle is as follows:

we aggregate the drive shaft - remove the rear wheel tire and put on a tire with a diameter of up to 2.5 cm. This equipment will help to take the engine speed and, like a gearbox, reduce the speed;
we weld the stand from the corners with electric welding - it will help to install the engine from the chainsaw;
alteration of the clutch - you can use a centrifugal one from a factory saw, connecting it to the wheel;
we adapt the gas tank - it can be located next to the engine, or on the frame;
we fix the wire from the ignition system of the motor to one of the bicycle handles;
attach a cable from the carburetor to the throttle handle so that the throttle control is simple and quick;
we equip the motorbike with protective equipment: mirrors, a flashlight, and proceed to the test homemade bike from a chainsaw.

As you can see, it is not so difficult to put a motor from a chainsaw on a bicycle.

How to make a moped from a chainsaw?

The dream of the youth of most of our fellow citizens was and remains a moped. It develops a higher speed and has a structure that is more perfect than the above described motorbike. Buying a ready-made moped is not a cheap pleasure. We will tell you how to make it from scrap materials.

For this you will need:

a motor from a serviceable powerful saw (in our version, this is the "Friendship" model);
2 wheels from an old bike;
pipe with a diameter of 2 cm (metal);
cable;
bicycle sprockets; as well as forks;
old motorcycle parts - a ready-made fuel tank, a headlight, and a seat if desired, although you can also make it yourself;
steering part;
throttle lever.

The process of creating a moped looks like this:

we cook a frame to which we connect bicycle wheels, forks, as well as a gas tank and a lamp;
adapting the motor - the composition of the installation will depend on the configuration of the frame;

we fasten the gas tank and battery;
we check that the newly installed elements do not dangle;
we make a chain drive - it will allow the wheels to receive the motor torque and move. You can use a belt instead of a chain pulley. But we must not forget that its wear will be noticeably higher;
we set up the ignition system - we connect the battery and the brake lever with it;
we fit the exhaust pipe.

The assembly process is complete: you can start testing the moped.

DIY chainsaw karting: step by step assembly

Karting is a modern vehicle that can cover a considerable distance in a short period of time. Exclusive kart is the dream of every car enthusiast. It is not necessary to participate in races with it: you can easily move on rough terrain, on rural roads, and in general everywhere where a larger car will not pass.

Among possible options rigging has gained immense popularity home-made karting from a chainsaw - no less powerful and productive than their serial counterparts. Let's consider in stages.

Preparatory stage

It starts with a detailed drawing and design. We suggest that you familiarize yourself with the finished drawing, which will save time on design;

The proposed dimensions are suitable for a person of average height. For teens and tall people the design must be tailored to their individual parameters. For teenagers, you can use the other scheme below.

Putting together the base of the construct

This is a chassis that will require:

square pipes (up to 10 m);
steel pipes;
thick steel plate;
bottom blocking equipment;
armchairs.

The process looks like this:

pipes are cut according to the proposed scheme and welded by electric welding.

Here's what should come out after welding;

the front axle is equipped with plugs;
the rear axle is aggregated - it is welded to the frame itself in such a way that its turning is ensured;
the bottom is cut out of metal or solid wood according to the drawing and fitted to the frame;
seat - in this case, you don't have to bother and take a ready-made one from an old card or car.

Karting equipment by motor

remove the motor from the chainsaw;

we make a base for the motor - from a steel plate and a corner. Its pulley must match the last frame structure;
screw the pulley with screws;
we take 2 metal rods, which we bend at right angles - this will drive the kart steering wheel;

adjusting the brakes - it is desirable that the braking extends to all 4 wheels. Do not forget about the brake pedal: it will be very inconvenient to press the brake with your hands;

we equip karting with wheels - wheels with a small diameter from an old racing car are suitable;
we adjust the ignition - we connect it to the throttle valve and the gas handle;
reliability control assembly and testing of the finished unit.

Go-karting is a luxury for an ordinary person, but with the help of improvised means, you can create a budget version - go-kart with a chainsaw engine.

No less famous homemade product, which the domestic "Kulibins" have learned to make. To recreate it, we need:

a scooter designed for the weight of the person who will be driving it. It is desirable that he initially had a manual braking system. The pneumatic wheelbase of the scooter must be strong;
the chainsaw from which the engine is removed - medium and high-power models are suitable.

The scooter assembly process looks simplified compared to previous homemade products:

First, remove the motor base and fix it at the rear of the scooter frame. We make sure that the motor and wheel sprockets match;
we fix a manual accelerator with the ignition of the chainsaw - so the operator can control the movement process;
if necessary, equip the scooter with a brake pedal, but in most cases, the lever for manual control of the scooter is enough for its full operation.
testing a scooter from a chainsaw - in case of serviceability, the new motorized device is ready and can be used.

Homemade children's ATV from a chainsaw

The last homemade product we will look at will be dedicated to ATVs. In fact, building an ATV requires similar materials as for a go-kart or tricycle:

engine from an old powerful and working chainsaw;
reducer - increases the thrust of the motor and takes over its working speed;
ATV frame - it should be stronger and more stable;
driver's seat - it's good if you have an old moped seat: a teenager will be more comfortable in it than in a bulky car;
wheels with rough tread, diameter not less than 34-35 cm each. This will improve the cross-country ability of the ATV and make it an analogue of an SUV.

If desired, the prefabricated structure of the ATV can be brought to perfection with shock absorbers: the ATV's maneuverability will increase, and the working stroke will become smoother.

Homemade vehicles are cheap, but not always reliable. They can only be used with strict adherence to all safety regulations.

Survival ideas: what you can do with your own hands from a regular chainsaw

This tool is convenient in that it does not depend on the current source. You can work with it away from home. If you suddenly need a pump, generator, snow clearing device or ice ax - the chainsaw will become the heart for any home-made car. So you will not only save money, but also get really powerful and reliable equipment. Based on a 4-8 hp gasoline engine. with. you can build a home sawmill, a snowmobile sled, a generator for lighting, and even a cultivator. Consider the most popular homemade chainsaw products and their manufacturing technologies.

Powerful chainsaw snow blower

The owners of the suburban area rarely rejoice in the heavy snowfall. At such a time, they have one main concern - to clear the driveways and the passage to the house, remove the snow from the parking lot for the car and make their way to the exit to the highway. Not everyone has enough energy and time to work with a shovel. Therefore, snow plows are very popular in the season.

But such a tool costs at least 30,000-35,000 rubles, and not everyone can afford it. What's in technical characteristics is it an instrument? All the same petrol engine with a capacity of 5-8 liters. with. And since this is so, then the power of the chainsaw is theoretically enough for a homemade snow blower. The device of the snowplow is simple, pay attention to the diagram:

And now a small master class on making the device:

Image	Description of work
	The main shaft, on which the shovel will be mounted, will require metal racks. In this case, the racks from the VAZ 2110 were used. They need to be welded together using a metal sleeve.
	You will need a motorcycle sprocket to drive. It is welded into the shaft.
	The auger will require two sheets of rectangular metal and spiral pieces. All this is cut from durable metal with a thickness of at least 2 mm.
	The vanes and spirals are mirror-welded to the shaft.
	The shovel body is made of metal with a thickness of at least 1 mm. The shaft is mounted inward on automotive bearings.
	In the upper part of the body, you need to make a hole for the snow discharge pipe.
	A movable cover should be installed on the snow discharge pipe so that the direction of flow can be adjusted.
	The saw chainring must be replaced with a motorcycle chainring. To do this, you have to make a boring.
	The engine itself needs to be mounted on a frame with rubber pads for shock absorption.
	To fix the handlebar, a sturdy steel pipe stand should be made.
	The ignition and speed control system can be taken from a moped or motorcycle.

After assembling the main part, it remains only to install the skis and the fuel tank on the structure. The entire structure as a whole will weigh no more than 35 kg, so that even a fragile woman can manage it.

As a result, the whole device will look like, see in this form:

Do-it-yourself universal snowmobile from a chainsaw

Winter fishing or hunting - favourite hobby many. You cannot get to the cherished lake without a snowmobile, and there is no pleasure in running through the forest to chase game waist-deep in snow. Such a "toy" costs a lot - from 80,000 rubles. And again, the chainsaw will help you out. What you need to prepare: A suitable sled with skis or tracks. The sled itself can be welded from a steel, or better, an aluminum corner. The lighter the structure, the faster it will run. As a basis, you can take the device of a children's snow-scooter on three skis according to this scheme:

The impulse for movement of the self-made self-propelled self-propelled machine from the chainsaw is transmitted by the caterpillars with hooks, which push the sled forward. You can replace the tracks with a shovel with 7-8 blades, it is installed under the seat. The principle of installing the engine is the same as on a snowmobile - with a drive and gears from a motorcycle or moped.

As an engine for a snowmobile from a chainsaw, you can use "Friendship" or more modern models, for example, "Calm". The steering wheel will fit from the old bike, the motor control is displayed on it, or, if possible, immediately adapt the structure from the moped - there all the controls are ready.

Snowmobile brakes were invented by cowards. But in fact, with a chainsaw engine, it will not develop a dangerous speed, so you just need to throw off the gas. Do not be reassured, such a product will not be registered by any car inspection. So you can't use it on the roads. But on the other hand, you don't have to pay tax and undergo technical inspection. For driving in the dark, do not forget to put a flashlight on the structure.

Homemade sawmill from a household chainsaw

In private households, construction never stops. I rebuilt the house - I conceived a gazebo, finished the gazebo - I need a garage, a fence, a barn, a doghouse. And so on ad infinitum. If there are no extra funds, the cheapest way is to buy round timber and dissolve it yourself into boards of the required size. A home sawmill can be built from the same chainsaw.

Image	Description of work
	We replace the standard nuts with special fasteners, they are bored out of a hexagon.
	On the sawing table on a metal pipe, we install a movable coupling with a platform for attaching the saw.
	The thickness of the board is regulated by means of movable stands. The higher you raise the racks, the thicker the board will be.
	It remains only to fix the saw on the movable coupling with hexagons and work.

A primitive sawing device can also be made directly at the felling site. For work, you do not need to change the design of the unit, you just need to make a small device for the chainsaw that guides the movement of the tire. See how to do it:

DIY chainsaw ice screw: diagram and practice

They say that you can't pull a fish out of a pond without difficulty, but in winter I would like to limit this work by twitching a jig. The avid fisherman is never limited to one hole.

But if the ice is 0.5 m thick, you will spend most of your time drilling, losing strength and mood. Ice auger will help to cope with this task quickly and effortlessly. Let's see how much such a gadget costs: from 8,000 rubles. Why buy it when you have a chainsaw on hand? To make an ice screw, you need an old electric drill - we will make a drive from it. How to make an ice screw from a chainsaw with your own hands:

Image	Description of work
	An electric drill will require a working gearbox.
	From a part of the anchor from a drill, a sleeve and a head for 27, you need to make such a tool. He will directly transmit the rotation of the borax.
	Another element needs to be made with your own hands from a piece of metal and a pipe. This is a gearbox mount.
	The fixing structure is fixed to the saw with two screws.
	This is how a gearbox with a sleeve attached to a saw looks like.
	A drill is inserted into the sleeve. In the future, a drill tube is put on it and fixed with a bolt.

Important advice! The key to successful operation and safety of the tool is the presence of a guide for the movement of the drill. Many neglect this part of the design, and as a result, the drill breaks in the first minutes of use.

How a homemade design will work is shown in the video:

DIY chainsaw motor-drill

The motor-drill is designed according to the same principle as the ice-drill. The difference can only be in the nozzle. In earthworks, the speed of rotation of the spiral should not be too high, therefore, in a self-made design, it is necessary to provide for speed control and a simple shutdown.

DIY chainsaw boat motor

If you compare the cost inflatable boat and the motor, it turns out that the boat is at least twice cheaper. The most unpretentious gasoline outboard motor of 4 horses will cost 40,000 rubles. Expensive, to be sure. But the PATRIOT PT 6220 chainsaw with a capacity of 4.35 liters. with. - only 8 900 rubles. The power is the same, but the cost of the motor is five times cheaper! And what, tell me, is the point in purchasing an expensive boat engine?

Chainsaw manufacturers have long clarified all these points and quite officially release all kinds of attachments for them - from a drill to a propeller drive. The price of a boat attachment is 5,000-6,000 rubles. At the same time, there is no need to make significant changes to the construction of the saw, which means that after fishing you can easily change the attachment and cut firewood for the fire. Now about how a homemade boat drive works:

Image	Description of work
	Remove the tire and tensioner from the saw.
	The lower part of the rack with a screw is made of a gearbox from a drill, a cone from a petrol cutter, an oil seal and the screw itself.
	The ribbed tube is made of aluminum.
	We use a clamp to secure the motor to the boat's transom. A platform for fixing the engine is welded to it.
	To connect the propeller to the motor, the author of the project uses a clutch made of vtoroplast.
	The platform with a motor is movable, its movement is controlled by a handle. The power control is also located on it.
	The saw is installed in such a way that the sprocket fits into the clutch, and the standard bolts fix the motor on the site.
	For fastening, you will have to prepare suitable nuts, standard nuts will not work.

And now the material on how this device works in practice:

How to make a moped from a bicycle and a chainsaw

This homemade product from the Druzhba chainsaw is the most popular of the DIY options. The one on the moped is always the first guy in the village, so many craftsmen start with just such a device.

Important! The structure of a bicycle powered by a chainsaw must be particularly durable. If not, reinforce the frame with additional struts.

A driven pulley is installed on the rear wheel, the engine is securely welded to the frame. How it will look as a result in this plot:

The Druzhba chainsaw moped is quite powerful, so be extremely careful and do not forget about the traffic rules!

Continuing the auto theme: do-it-yourself karting from a chainsaw

Young karting coaches know that more than one engine will burn out during the training process. The problem is that the child driving the car gets lost at speed. For this reason, to start classes, training karting with a walk-behind tractor from a chainsaw is quite enough.

The karting device is primitive: the frame, seat, steering wheel and, in fact, the engine. The principle of installing the engine is the same as on a moped, the only difference is in its location. This is how it looks:

On such a go-kart, children can drive without risk on a track adapted for this, and the speed will be quite decent - up to 80 km / h.

DIY chainsaw generator

Among the tools for survival in any conditions, the generator is far from the last place. What to do if electricity suddenly went out at your dacha, and you, not only will be left without light, but also the heating will stop working without a pump. For your own safety net, it is better to prepare in advance the simplest generator from a chainsaw.

Use a bicycle gear to transfer the torque. In this case, the saw must operate at minimum speed.

This is how it works:

Chainsaw winch

A winch is often needed on the farm: it will come in handy at a construction site for lifting building materials, pulling vehicles out of impassable spring mud and in many other unforeseen situations. Again the chainsaw will help mechanize this device.

There are ready-made attachments on sale - winches. They work in this way:

But you can make a simple device with your own hands. You will need to make a sturdy metal frame to which the motor will be mounted and mount the gear shaft.

DIY gas cutter from a chainsaw, or How to make a grinder: video

The gas cutter is the same grinder, independent of the electric drive. Agree, the tool is necessary in the household. To make it, you need a knot from a grinder, a powerful enough chainsaw, a belt and a pair of tires. How to make a grinder from a chainsaw:

The advantage of the resulting tool is that it is completely autonomous and has good power. Perhaps, it surpasses in its characteristics any factory electric grinder. It is only necessary to take into account that the device is dangerous and requires a very careful approach to itself. The most common problem is a broken disc, its fragments can cause serious injury. Therefore, it is strictly forbidden to work with such a tool without a protective cover.

Adult toy: radio controlled chainsaw car

And this toy is definitely not for children. It's hard to say which practical use can be found radio-controlled car from a chainsaw, but its creators were hardly looking for it. For the keen modeler, the complete device report is:

Homemade from the Ural chainsaw

Why most often you can find information about homemade products from the Ural saw? It's simple: a powerful, but heavy and noisy saw with reliable Soviet quality was left out of work for many. It was replaced by light and comfortable models of European and Chinese production.

"Friendship" and DIY from this chainsaw

Druzhba is the progenitor of the Urals, and it has become a popular homemade base for the same reason. "Druzhba" has a powerful two-stroke engine of 3 liters. with. The device even has a chain brake.

"Ural" and "Druzhba" are distinguished by increased strength and endurance, like most engineering solutions of the times of the USSR. In addition, they are fueled with low-octane gasoline, and this is a significant savings. The only drawback of this technique is weight.

Moped with gasoline engine

If you don't want to refuel the car every day, and riding a bike is too tiring, then a gasoline homemade moped will be the perfect solution to your problem.

What do we need

Nowadays, there are many ready-made kits that include an engine of the required power and other parts necessary for rebuilding a bicycle. Buying such a kit is a great option for those who want to become the owner of a bicycle with a motor, but do not have the opportunity to make fasteners with their own hands or find a suitable engine.

However, there are situations when, despite possible difficulties, you want to do all the work yourself. In this case, it is worth starting with the choice of a suitable power unit, for the role of which one of the parts of the old and unnecessary household utensils may be suitable. A lawn mower or a chainsaw is the most suitable donor for a heart transplant, but do not forget about the power of each such unit. So, a homemade moped from a bicycle should be equipped with a 2 hp engine. and a volume not exceeding 50 cm3. A weaker motor will not be able to move the bike, and you will have to pedal for a while.

We equip the frame

The bicycle frame becomes the main location for all parts and elements of a future moped. In particular, the engine, gas tank and battery are attached to it with the help of fastening clamps. The most successful variant of their location is as follows: the battery is on the upper tube, the engine is at the junction of the lower front and seat tube, and the gas tank is located directly next to the motor.

We make pulleys and install them The next step towards creating a moped with our own hands is the manufacture of pulleys - special transmission units, through which the motor force will be transmitted to the rear wheel. As required materials, you can use small wheels (about the size of a CD), complete with an external barrier. A prerequisite for creating pulleys is the strength of the parts used and the reliability of their fastening.

Installation of these parts on the bike is carried out in the following sequence:

1. The front gear wheel is connected to the motor shaft.

2. The second pulley attaches to the rear wheel hub of the bike.

3. Then the belt is put on the pulleys, setting the tension force as for the chain.

Note! The belt must adhere well to the wheels, since the accuracy of the transfer of power from the engine to the wheel depends on this. In the case when a chain drive is used instead of a belt drive, gears take the place of the pulleys.

Motor connection

After the transmission is installed on the bike, you can proceed to connecting the power unit. For this, its working body is connected to the battery and the "ignition" mechanism is assembled. The motor mounted on the bike is associated with a brake lever, which is also an integral part of the do-it-yourself moped assembly. The tension of the connecting cable must be set so that the motor can start freely through the handle.

Interesting fact! Globally, there are about twice as many bicycles as cars and motorcycles. In addition, 50 million new non-motorized two-wheelers are produced annually, while conventional cars only add 20 million to the ranks.

Assembling a moped with a gas engine

Compared with the previous version, this method will allow you to get a more "advanced" vehicle, which is almost completely consistent with a real moped.

What do we need

To accomplish this task, you will need a gasoline engine itself, spare parts from a real moped (wheels, shock absorbers, brakes and an exhaust pipe), a strong, welded bicycle frame and working tools (including a welding machine). Considering that in this version you are going to make a real motorcycle out of a bicycle, its frame must have the appropriate weight and strength.

You can try to find a part from a small moped, but if it doesn’t work out, then a “skeleton” from a bicycle in the style of “Stork” or “Yew” will do.

Preparing the frame

Note! If the selected engine is not completely functional, then it should be carefully re-enumerated, replacing the failed elements. Although you still do not fully understand how you can make a motorcycle out of great, the good condition of all the elements used should not cause any doubts.

Create torque

We connect the engine

After completing all the above steps, it remains only to correctly connect the motor. To do this, the clutch and throttle valve must be connected to the ignition lever by means of drive cables. The tension force is selected so that the motor can start immediately and start spinning the wheel. As soon as you connect the power unit, consider that you have already succeeded in making a bike on a motor.

That's all. Another answer to the question "How to make a motorbike with your own hands?" I'm ready now.

Do you know? Cycling helps you stay in top shape. For example, cycling for an hour can help you lose 600 calories.

Building an electric bike

If you don't like the idea of using a gasoline engine on your bike, then you can consider an alternative electrical upgrade to your vehicle.

Benefits of electrical equipment

The electric engine runs quieter, does not emit harmful exhaust gases into the atmosphere and does not heat up as much as its gasoline counterpart.

In the case of a home-made electric bike, the role of the engine can be played by a car starter, screwdriver, or any other power plants available on the farm.

Along with the electric motor, an important component of the already converted vehicle is the controller (or regulator), the task of which is to accelerate the moped bike under optimal operating conditions of the power plant. To start the movement, a very small current flows from the controller to the motor, due to which the motor starts to rotate smoothly. In a braking situation, the regulator recuperates the energy of the movement into an electric current that supplies the battery. The battery is practically the same fuel tank, but much more environmentally friendly. It often consists of a matrix and batteries connected to a specific circuit.

Step-by-step guide to build

There are quite a few ways to assemble an e-bike, but the easiest way is to connect the drive to the tire. If you had a Soviet-made bicycle, then you probably came across a dynamo to connect a headlight. The same principle is used to connect the electric motor to the wheel. Of course, when using this method, the drive efficiency will be very small, but for testing a vehicle on electric traction, this is quite enough.

The second option, how to make a good electric bike with your own hands, involves the installation of an additional star on left side wheels and engine mounting with a star on the trunk. If we connect them with a chain, then we get the simplest chain drive. However, as in the previous version, there will be mechanical losses, and appearance it is not particularly attractive.

Therefore, it makes sense to consider the third and most suitable way of converting an ordinary bicycle into an electric bicycles. It provides for the use of a special motor-wheel, which allows you to get an electric motor for a bicycle with an excellent aesthetic appearance and high efficiency, which will make it possible to create a unique vehicle with your own hands. The motor-wheel differs from a conventional wheel by the presence of a drive mechanism in the central part. It connects to the control unit using wires and allows you to create a front-wheel drive bike, without changing the classic transmission.

If there is a desire and opportunity, you can install two motor wheels at once. The installation process includes the following steps:

1. Mount on the carriage axis new star and a belt pulley;

2. Then the shaft with the drive pulley is attached to the seat tube;

3. The pulleys are connected to each other with a belt, and through the wires the shaft is connected to the power source;

4. The wires from the battery are routed to the steering wheel switch.

Note! The battery is best placed on the lower front tube of the frame or on the trunk.

Summing up all of the above, it should be noted that it is still possible to assemble an electric bike in the "do it yourself" style, but for this you need to find all the necessary parts, spend a little time and nerves. The operation of such a vehicle itself should not be accompanied by any difficulties, of course, except for the surprised looks of passers-by, which, however, is rather a compliment to you.

Interesting to know! When boarding a bicycle, most people approach it from the left side, throwing right leg, which is explained by the presence of a chain and a star on the other side. The habit of placing the chain on the right side came from horseback riding, since the epee, located at the rider's left thigh, made it difficult to land on the right.

A moped, like a bicycle, is an economical and convenient means of transportation. This vehicle travels faster due to the presence of a drive. The dream of every cyclist is to move quickly, effortlessly. It is possible to make a dream come true: you just need to equip the bike with an engine.

Consider how to correctly design a moped from a chainsaw from improvised means and parts.

How to make a moped from a chainsaw and a bicycle

battery;
pulleys, gears;
transfer belt or chain;
drive cable;
clamps for fastening;
tools: screwdriver, pliers, etc.

Use disc-sized outer stop casters to create the pulleys.

Do not forget about the strength and reliability of the fastening of the parts.

The assembly of the moped continues, we mount the assembled parts:

The front transmission unit is connected to the engine shaft.
We attach the second pulley to the rear wheel hub.
We put a belt on the transmission nodes. If using a chain, use gears instead of pulleys.

Ignition from a chainsaw to a motorcycle

Chainsaw parts are also used to modernize outdated vehicles or vehicles requiring repair, such as a motorcycle. A saw ignition system is often used to enhance this vehicle.

You will need:

flywheel;
flywheel spacer with key;
fan;
coil with high voltage wire;
aluminum plate for mounting the coil;
bolts, nuts.

Chainsaw ignition is suitable for motorcycles Ant, IZH Planet. Unlike magneto, such ignition is reliable and durable, not afraid of shaking and water.

For the correct assembly of a moped with your own hands, reliable service, for alteration and construction of other equipment, listen to the advice:

Before assembling the motorcycle, make sure that the main part - the bicycle - is in optimal technical condition. The modernization will increase the stress on all of its parts.
Check carefully the condition of the petrol tank. Fuel must not spill out as this could create a fire.
In addition to engine power, don't forget about volume and weight. The volume should not exceed 50 cm³, weight - no more than 6 kg.
When installing the belt, make sure that the part is firmly attached to the wheels, otherwise the accuracy of the impulse transmission from the motor to the wheel will decrease.
With the help of a chainsaw motor, you can independently design other equipment: go-karting or tricycle. You will have to make an effort: weld a strong metal frame, prepare a working gearbox.
With a sturdy frame, gearbox, driver's seat, at least 35cm wheels and a saw motor, try building an ATV.

Today, almost anyone can make a moped from a bicycle for personal use. This technique is especially common in rural areas. Basically, such a moped is assembled on the basis of an old bicycle, to which a gasoline engine with a small volume is adapted.

Before starting the modernization, you need to find out what a moped is. It is a vehicle with an engine volume of no more than 50 cm3. Maximum speed, which a moped can develop is 50 km / h. Its main difference from a motorcycle is its chain drive from a bicycle. In this case, to start driving, you must pedal until the engine starts.

Selection of parts and materials

In most cases, it is used, since this is the most suitable option for a bicycle. In addition, it can be easily purchased at a low price. Can buy modern bike and the motor is better, but from a financial point of view it is not entirely profitable. For this amount, you can easily purchase a good Japanese moped with a run, which eliminates the need to tinker it yourself.

also in recent times some motorcycle manufacturers began to produce special kits for creating homemade mopeds from bicycles. To install such a motor, you must follow the instructions that come with the motor. Subject to all points, installation will not bring any problems. But many still choose to create a moped with a chainsaw engine, since it turns out a little cheaper.

The first step is to decide on the power of the motor. Engines with one horse power are not able to set the bike in motion on their own, for this you will have to accelerate it, pushing off the ground with your feet. The two-horsepower motor does this better. Such an engine is capable of self-acceleration and without the aid of pedals to climb a hill.

In addition to the engine, you need to get a pulley, which can serve as a rim from children's bike, a belt that will transmit torque to the wheel. In addition, you will need tools and materials for the construction of the motor mount. The easiest way to mount the engine is above the rear wheel. To do this, you need to take care of strengthening the trunk, as it will not support the weight of the motor.

It is best to use 4 mm steel parts for making the motor mount. But it is worth remembering that creating a powerful frame increases the weight of the moped and the load on the wheel, which will lead to a decrease in the performance of the motor. It is necessary to develop a structure that will be strong, and at the same time not too heavy. You can connect it to each other using a welding machine or bolts.

Assembling the structure in the second way is much easier, but of lower quality, since the bolts can loosen while driving, which in turn can lead to a sudden destruction of the entire structure. Also, the motor can be attached to the bike frame with conventional steel clamps. This is a simple and reliable connection.

After that, it is necessary to mount the pulley on the drive wheel. As already specified, a wheel from a small bicycle can play the role of a pulley. The main thing is that its diameter is twice less wheel moped. Also, instead of a pulley, you can use an additional sprocket, but for this you need to change the belt, not the chain. Both the one and the second solution have the right to life, it all depends on the available spare parts and materials.

After installing the engine and belt drive, it is worth starting to equip the bicycle handlebars, on which the accelerator handle should be attached. For this, you can use a metal cable. You can buy it at a hardware store or hardware store. It must be pulled along the frame, in the same way as the brake drive passes. The accelerator handle can be made from a brake handle. This method is the simplest control of the engine, that is, the increase in revs will depend on the pressure on the handle.
This type of mopeds have become a favorite vehicle for many.

Since they consume very little fuel, do not need expensive repairs and maintenance, and they do not need a license to operate them. In addition, the cost of these homemade mechanisms is quite low. In some cases, it is used, since it is a little cheaper, but safer. All mechanisms are mounted in a specific place on the frame, for which special fasteners are provided.

Making a moped out of an old bike isn't that big difficult task that anyone can handle. After assembly, it is necessary to go through a run-in near the assembly site so that there are no unforeseen problems during a long trip.
