Today trade can offer a large number of various models of scooters of domestic and foreign manufacturers... A person who wants to buy a vehicle has a huge choice. However, even with such an abundance of options, not everyone finds what they like. Someone is not satisfied with the dimensions and weight of the car. He is looking for a more compact device that can fit, say, in the trunk of a car. Someone considers the design of modern "iron horses" not attractive enough. He wants to show his own and collect his own. Such people are interested in how to make homemade moped... Here are some helpful tips.

What you may need

In order to make a homemade moped, first of all, you should decide on the details that will be involved in the assembly. In most cases, the design is based on an unnecessary bike. Immediately you need to think about where all the details will be located. The most cumbersome of these is the engine. It is usually located in the area of ​​the rear rack or at the bottom of the frame. If the frame has such a structure that the placement of the engine will create inconvenience when the moped is moving, then it can be made separately. This will require welding. The frame should be welded from bicycle parts that are specially designed for the appropriate load. If necessary, you can change the geometry of the desired part. For this, an emphasis is applied and The use of water pipes is strictly not allowed, since they do not have sufficient strength. Such a homemade moped won't get far. Engine mounts can be cut from iron sheets at least 5 mm thick and welded to the frame.

Moped engine

Here, craftsmen usually follow different paths. Some use engines from agricultural machinery. For example, mechanisms from walk-behind tractors or chainsaws. Others build a homemade moped using special bike motors. For example, a Chinese motor of the "D" series, or simply "cheap", is popular among technicians. What to use - everyone decides for himself. Perhaps the old one from the saw was lying in the closet, and it should be attached somewhere. We need to put it in a homemade moped. However, the best advice here is to use a standard bike motor. So there are more guarantees of its reliability. The engine should be installed on the prepared mountings. If it uses a chain drive, then a standard bicycle sprocket is acceptable for torque transmission.

Brake system

Driving through rural (and not only) areas, you can often observe people moving on a bicycle with a motor adapted to it. Such a homemade moped is usually assembled from an old bicycle (it can be "Ukraine", "Sputnik", etc.) and a small gasoline engine.

A homemade moped is assembled from an old bicycle and a small gasoline engine

Most often, a power unit extracted from a friendship chainsaw is used - it is best suited for such a design, plus finding it at a fairly low price does not pose any problems. Of course, as a "base" you can use more modern bike and a motor, however, the feasibility of such a decision from an economic point of view raises some doubts - for the price you pay, it is quite possible to buy a good used Japanese moped without having to do anything with your own hands.

It should be noted that especially for lovers of home-made units, many companies produce motors designed for installation on bicycles - having bought such a kit, you just have to follow the attached instructions. With proper implementation of all points, installation should not cause any problems. We will talk about the option described in the first paragraph - how to make a moped from an old bicycle and a chainsaw (or a lawn mower - this is not so important).

The first thing to determine is the motor power. Engines with a power of 1 h.p. will not be able to set your vehicle in motion on their own, that is, you will have to give it some acceleration, pushing off the asphalt with your feet. 2 h.p. - this is much better.

A moped with a 2 hp engine. will be able not only to start independently, but also to take you up the hill, that is, you can forget about pedals altogether.

For a homemade moped, it is better to use a 2 hp motor.

In addition to the motor, we need a pulley (a wheel from a small children's bike), the belt that will be tightened on this pulley, as well as the set of tools and materials from which you will make the fasteners.

The easiest option is when the motor is mounted on top of the rear wheel. In this case, you will have to make your own fasteners, since the bike rack may simply not withstand the weight of the motor. The optimal solution would be steel elements with a thickness of about 3-4 mm. Do not overdo it here - remember that a too powerful frame, firstly, will increase the load on rear wheel and secondly, it will increase total weight moped (accordingly, it will be more difficult for the engine to accelerate it).

Try to find a "golden mean" in this matter between the strength of the structure and its weight. Connections in this structure must be made by welding or, if you do not have a welding machine available, by bolts. The second method is a little easier to implement, but less reliable - bolted connections tend to loosen, so there is a certain chance that your moped will simply fall apart one day. The engine itself can be attached to the frame using conventional steel clamps - this is the simplest and most reliable solution.

Video tutorial: how to make a moped out of a bicycle

Next, you need to install a pulley on the rear wheel. As already mentioned, a wheel from a children's bicycle, which has a diameter one and a half to two times smaller than the diameter of your bicycle wheel, is perfect as a pulley. You can also use a gear - in this case, the belt will be replaced with a chain. In general, these two solutions are approximately equivalent, respectively, it is worth choosing the one for the implementation of which you have the materials (or they are easier to get).

When the motor and the belt (or chain) transmission are installed, it remains a small matter - to bring the throttle stick to the handlebars of the bike. For this, a regular cable is used, which can be bought at any hardware or hardware store. On the frame, it is carried out by analogy with how the brake cables go (you can look at the structure yourself, and you will understand everything). The throttle stick can be made from the brake lever - this is the easiest way. Accordingly, you will accelerate by pressing this knob.

As you can see, it is quite possible to make a moped out of a bicycle at home, moreover, there is absolutely nothing complicated in this work. The main thing is, when you are finished assembling - run your moped near your house before driving out onto the road. So you will definitely be sure of its reliability.

A motorcycle from a chainsaw with your own hands is a way out for those men who do not want to spend money on a car and its subsequent maintenance and who do not like to pedal a bicycle. In this case, an excellent way out of the situation will be a moped from a chainsaw and a bicycle, which you can assemble with your own hands in the garage by purchasing some necessary, missing parts and spare parts. The alteration process itself is not particularly difficult.

Before starting the assembly or if you have any questions, you can always refer to the drawings and numerous video reviews available on the Internet.

The principle of a homemade moped from a chainsaw

As a basis for a future moped, you can choose an old bike that you want to breathe into. new life... You will also need a chainsaw to install the motor on your bike. In this way, you get a bike that you can upgrade: repaint, install wider wheels, change the steering wheel and do other procedures that will make your homemade bike more like a motorcycle.

Choosing a chainsaw for a bike

The most important factor by which you need to choose a chainsaw for assembling a moped is the power of the power unit. The most suitable power is 2 horsepower because less power will not be enough to get the bike moving. The volume of the engine should be no more than 50 cm3. Experienced homemade moped drivers also recommend choosing engines from old mopeds or lawn mowers.

What does it take to make a moped from a chainsaw and a bike?

For the most part, converting a bicycle into a moped with your own hands by attaching a motor from a chainsaw to it does not require special skills of a locksmith or engineer. If you are new to this business, then numerous drawings of a chainsaw moped, as well as educational video reviews, will help you. Also, not every man in the garage has everything he needs to make a motorbike from a chainsaw with his own hands. Therefore, before assembling, it is recommended to study the list of necessary parts, fasteners and spare parts and buy the missing elements.

In specialty stores, you can find whole kits, which include a ready-to-install engine, fasteners and other parts that are necessary to transform a bicycle into a moped. This kit will greatly facilitate the process of assembling a motorcycle, since there is no need to select an engine of suitable power, fasteners, battery, transmission belt, cable, etc.

Speaking of tools, you will really need everything. popular types components of the auto mechanic's kit: screwdrivers, pliers, keys, wire cutters, etc.

Assembly instructions and drawings of a homemade moped

Firstly, we will first analyze the simplest and most affordable option on how to make a moped from a chainsaw from the photo above. When assembling, the question often arises of how to put a motor from a chainsaw on a bicycle. It is important that it is securely attached and does not move while riding. For this type of homemade motorcycle, you need to fasten the following parts with clamps in certain places:

• the battery is installed on the upper pipe;
• the bike motor itself from the chainsaw is attached at the intersection of the lower front and seat tubes;
• fuel tank - near the engine.

The next step in the rework is to create and install the pulleys on the bike. They are needed so that the operation of the engine provokes the rotation of the rear wheel. As a rule, wheels with an external barrier are used for pulleys, which are about the size of CDs.

When choosing wheels, take into account the strength and reliability of both the material itself and the fasteners. To install the pulleys, the front wheel is attached to the motor shaft, and the second pulley is attached to the rear wheel hub. Next, you need to slide the belt over the pulleys. Sometimes men use a chain instead of a belt. In this case, the pulleys are replaced with a chain, and the principle of its installation is no different.

The only thing left is the connection of the motor. First, the motor is connected to the battery, and then the ignition is assembled. To do this, you need to install the brake lever on the steering wheel and connect it with a cable to the engine.

If we talk about a more complex option, then as a result you will get a homemade transport, most similar to real motorcycle... The main differences from the previous design are in a more reliable and durable frame, wider wheels that can be removed from the old moped, the presence of shock absorption and the installation of the engine from the chainsaw.

The most convenient place for the engine will be a separate platform welded at the bottom of the frame. The fuel tank can also be placed there. An exhaust pipe is also attached to the engine. As for the battery, the owners of homemade mopeds recommend placing it closer to the steering wheel. The next step will also be the transmission and engine connection. All the nuances of how to correctly make a motorcycle from a chainsaw with your own hands you can watch in the video.

Many users insist to pay attention to how the belt holds on the wheels. The degree of its fixation affects the transfer of power from the engine, and, consequently, the driving process. The chain is a more reliable and durable part, but do not forget that when using a chain on a homemade moped, gears are used instead of pulleys.

The engine that you took out of the chainsaw must be fully functional. Otherwise, spend a little more time building the moped with your own hands and go over the engine. Try to fix the broken parts or replace them with new ones altogether.

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 powertrain, you will also need other parts: battery, pulleys and gears, transmission belt (which can be replaced with a chain), drive cable, and mounting straps. 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 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 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 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

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.

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.

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.

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 gasoline engine on a bicycle, then you can consider an alternative improvement of this vehicle with the use of electrical equipment.

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.

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 installing an additional star on the left side of the wheel and mounting an engine 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 very operation of such a vehicle 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 with right side came from horseback riding, as the sword, located at the rider's left thigh, made it difficult to land on the right.
