Chainsaw powered bike. What can be made from a chainsaw - homemade chainsaw

The chainsaw is very popular among home craftsmen, as it is a universal drive for original home-made designs.

Light weight and solid power, combined with compact dimensions, allows this "lumberjack's dream" to be aggregated with an ice drill and a bicycle, a sawmill and a winch.

Interesting homemade products from a chainsaw can be made by anyone who confidently works with a welding machine, grinder, and, if necessary, can also stand up to a lathe.

In this case, knowledge of the basics of design and drawing will be very useful, since the accuracy of all dimensions and build quality are the main conditions for the normal functioning of a unit powered by a chainsaw.

Without going into technical details, we will consider options for the most interesting designs using it.

Homemade options

The first thing that comes to mind when you think about what you can do with a chainsaw is its use as a sawmill. Many developers had to dissolve logs on a beam with this tool.

Holding the saw on weight in your hands is very difficult to control the accuracy of the entire length of the cut. Therefore, with a three or four-meter length of a log, it strongly moves away from the intended line. Solving this problem can be quite simple. To do this, the chainsaw is rigidly fixed on the frame, which moves along the guide profile.

The log in this case lies motionless and is carefully sawn along the entire length without wobbles and oblique seams. If you equip such a mobile carriage with four lifting screws, then you can accurately set the thickness of the sawn timber.

A sawmill from a chainsaw will also work on boards without problems, only in this case there will be too much waste, since its cutting chain is several times thicker than a band saw.

snowmobile

A light homemade snowmobile made from a chainsaw is more complex in design than a sawmill, since here you need to take out gas, clutch on the steering wheel, and also take care of the shock-absorbing suspension of the supporting frame.

In addition, you need to develop yourself or use ready-made caterpillar drawings and correctly transfer torque of sufficient power to it from the motor. Since the chainsaw does not have its own transmission, the clutch on such a snowmobile is centrifugal with a V-ribbed belt and chain.

To increase traction, a “traction” gear is placed on the caterpillar drive shaft, the diameter of which is larger than the size of the chainsaw drive sprocket.

There are usually no problems with the steering mechanism, since it is taken from an ordinary bicycle or scooter and modified in such a way that the central axis moves the rods that turn the skis. The engine power of a snowmobile must be at least 5 horsepower, so it is better to use a Ural chainsaw for this purpose.

The winter line of home-made vehicles will be supplemented by chainsaw snowmobiles, which are structurally simpler than a snowmobile. They are driven by a large diameter propeller that directly rotates the gasoline engine.

A significant limitation for the cross-country ability of such a machine is the low power of the chainsaw. Therefore, you can move on them only on a flat surface of rolled snow, ice of a frozen lake or river. To travel through the fields, you will need an engine with a capacity of at least 12 “horses”.

Those home inventors who would like to make a backpack-type helicopter out of a chainsaw should know the same thing. Such a machine will require not one, but at least two engines operating in a coordinated mode.

Moped

This vehicle is most often made for the sake of principle, and not for practical use. The main driving force of its creator is the desire to test his strength as a mechanic and prove to others the original use of this cutting tool.

The basis for the design is usually the old grandfather's Druzhba chainsaw and no less ancient bicycle, with which you can carry out any experiments on altering the frame for mounting the drive.

The power transmission here is carried out through a gear pair by means of a bicycle chain, and the start of such a homemade product is reminiscent of preparing for cutting firewood.

Less common are more advanced models, the basis for which is a mountain bike, equipped with reliable brakes and shock absorbers. Such a moped from a chainsaw is equipped with a gearbox with a gear ratio of 18: 1 and a variable speed transmission, which allows you to comfortably ride it at the speed of a conventional bicycle.

boat motor

This option for using a chainsaw is quite simple, since the task here is to transfer torque from the saw motor to the propeller. A homemade outboard motor does not need to install a transmission. For it, you will need to make a reliable adapter on the lathe from the drive gear of the saw to the propeller shaft. The screw can be used from a standard outboard motor.

The photo shows a variant in which there is a gearbox in front of the propeller that changes the angle of rotation of the shaft by 90 degrees. In simpler models, they do without it, fixing the engine on the boat so that the shaft is immersed in water at a slight angle.

Motor cultivator

It is difficult to make a full-fledged walk-behind tractor from a chainsaw due to a lack of power and traction. But a light motor cultivator based on it was able to build many home craftsmen.

The design of such a machine is very simple: the motor rotates a pair of gears and transmits increased traction to one drive wheel.

snow blower

The chainsaw motor does not care what to rotate - the cutting chain or the auger mechanism of the snow blower. Here everything depends only on the design abilities of the creator and his ingenuity.

Using a Stihl chainsaw with a power of about 3 kW, you can easily build a good device for cleaning the area from loose snow. To simplify the design, some craftsmen refuse to install wheels using conventional sled skids.

The most important part, which determines how well a homemade snow blower will do its job, is the auger assembly. It is driven by a gear pair and a chain. The blades are made of thick cord rubber, and the intake device is made of galvanized steel sheet.

frame design

Under the snow thrower, you can adapt a plastic sewer pipe by fixing it on the intake body.

Chainsaw asks for the sky

The most daring inventors have long been eyeing the possibility of using a chainsaw as an engine for an aircraft. However, the “strength” of this tool for the development of airspace is not enough. Therefore, no one has yet succeeded in making a backpack helicopter out of one chainsaw.

The calculations showed that this requires at least four chainsaws (total power from 20 hp) of a forced design, which would allow them to increase speed several times and work in a coordinated mode.

Motobur

This device is useful not only when building a fence or foundation from screw piles, but also during winter fishing, when dozens of holes have to be drilled in thick ice.

Since the ice drill operates at low speeds, in order to adapt the chainsaw motor, it is connected to the auger through a step-down worm gear.

Winch

A motor winch is a very useful device, because with its help you can not only easily pull out a stuck car, but also lift a heavy load to a height, pull a boat onto land or move a sawn tree.

The power of such a homemade product depends on the power of the used chainsaw, and its pulling force can reach 1500 kg. Such a winch must be equipped with a sling, hooks and anchors for attaching to the ground, a tree trunk or a car.

Power station

The camping power plant is assembled on the basis of Ural or Druzhba chainsaws. It consists of a frame, a motor with a gear reducer, a control panel, a generator and connecting electrical cables.

1 - chainsaw 2 - gearbox 3 - drive cord belt 4 - tension bar 5 - generator; 6 - control panel; 7 - clamps; 8 - carrier frame; 9 - toothed stop of the saw; 10 - nut for attaching the frame to the gearbox; 11 - drive pulley

A good owner will not throw anything away in vain, especially when it comes to high-quality metal. If you understand the nuances of metal heat treatment, you can make chain forged knife, which has served its resource.

Such a thing looks no worse than the creations of Arab blacksmiths who forged swords from the legendary damask steel.

Dear visitors of the site "Visiting Samodelkin", from the material presented by the author, you will learn how you can independently make a moped from the Druzhba chainsaw

Since Soviet times, many still remember such miraculous technology as a bicycle with a motor, in common people a "hole" is the middle link between a bicycle and a full-fledged moped. The technique is good, low fuel consumption, and the rights to it are not needed)).

The current generation is much advanced in terms of modernization, improvement, restoration, tuning. They remake factory equipment so that the designers do not recognize their offspring))

So the author came up with the idea to make a moped from the Druzhba chainsaw, but so that it does not look like a homemade product, but looks stately and elegant. The master already had experience in creating such equipment and had a ready-made moped available, and this masterpiece was created on its basis.

The frame is extended for bicycle wheels, a tank, a headlight and a seat from the Minsk-103 motorcycle are installed. Water cooling of the chainsaw engine was developed and applied, because after 20 minutes of operation the engine warmed up, the power dropped and, as a result, the operation stopped, and due to water cooling, the moped feels great and doesn't get hot.

And so, let's look at what exactly the author needed to create a moped?

materials

1. engine from the saw "Friendship"
2. bicycle wheels 2 pcs
3. tank, headlight, seat from the motorcycle "Minsk-103"
4. 4 cans of paint and masking tape
5. metal pipe 16-20mm
6. cable
7. chain
8. sprockets from a bicycle
9. bicycle forks, front and rear
10. axis
11. hose
12. plastic bottle
13. dropper
14. steering wheel
15. throttle stick

Tools

1. welding machine
2. grinder (UShM)
3. drill
4. set of wrenches
5. hammer
6. screwdriver
7. pliers
8. tape measure
9. sandpaper

Do-it-yourself step-by-step instructions for creating a moped from the Druzhba chainsaw.

As already mentioned above, the author already had experience in making a moped with a chainsaw engine, but the design was not so successful, and the maximum speed was about 35 km / h, the appearance also wished for the best. The author affectionately calls his brainchild "Stool"))

I wanted to create something more interesting and practical, and outwardly so that it looked like a real moped or chopper, so that it would not be a shame to ride down the street on such a technique, but, on the contrary, to catch smiles and enthusiastic glances of passers-by) This one was taken as an example and basis "bobber"

After that, a sketch was drawn up on a piece of paper with an ordinary ballpoint pen, I drew everything that needs to be radically changed and added.

The lower part welded from a professional pipe remained from the old frame, bicycle wheels and rear and front forks were added to the new design. During the first day of work, the author welded the frame, installed the tank, headlight, wheels.

All parts were naturally old and even rare, as well as welds had to be cleaned, and then the prepared surface was painted in several layers with periodic drying with spray paint, the master used Montana paint.

Also, after painting, when the frame was dry, another layer of matte varnish was applied, also from a can.

Bicycle wheels were also old, it was also decided to paint them, at first the rim was sealed with masking tape and the spokes of the wheel were painted.

The wheels were also painted and hung on a rope to dry faster.

I assembled all the painted parts into a single design and this is what happened.

But after working for several days, the engine unfortunately died, because it was also very old and probably its natural time had come to go for spare parts and remelting.

The engine was good, but I had to part with it.

In its place, I installed a new engine from the same Druzhba chainsaw, only newer than 1992, it was in store since the winter, and now its finest hour has come)

As they say, "Oh, trouble, trouble, chagrin" What to do? First of all, the author changed the gear ratio on the chain gearbox, consisting of bicycle sprockets and a chain.

It didn't help much, so that's not the reason. And then the idea came to make a water-cooled chainsaw engine. But how to implement it? In general, the author does the following, namely, he takes a plastic bottle and connects 2 hoses to it, one at the top for air intake, and the second at the bottom for supplying water through a dropper to the cylinder head of the Druzhba chainsaw engine. This kind of drip irrigation)) But according to the author, the engine stopped warming up at high speeds and feels great.

Well, the author turned out such a wonderful moped with a chainsaw engine and water cooling.

The master also made and shared beautiful photographs of his brainchild, let's see) motorcycles, then in no case do not throw them away, because they can be given a second life and they will serve you for a long time and surprise others, but today it’s not so good to get attention and just)

You have an example and step-by-step instructions, so take it and do it. Hold on friends!

Advantage: low fuel consumption, water cooling, speed 60 km/h.

Flaws: Wings need to be installed.

Ideas and suggestions for improving the design: (write in the comments)

This concludes the article. Thank you all for your attention!
Come visit more often and do not miss the news in the world of homemade products!

At all times, there were craftsmen who could make, it would seem, something truly amazing from ordinary things. It is thanks to such people that the development of science and technology does not stand still, but strides forward by leaps and bounds. In the event that there are no innovative ideas in your head, and the desire to do something with your own hands is haunting, then you can start with existing and proven practices. A homemade chainsaw for such a situation is the best fit.

Today you can find many ways to use a chainsaw for other purposes. There are a lot of things that can be done with this tool, as well as from it. Looking at some devices, I want to exclaim: “How did I not think of this before ?!”

The engine is the main technological link on the basis of which homemade products can be made. We have already learned how to design the following useful devices from a chainsaw:

• sawmill;
• means of transportation (land, water, air);
• cutting tool;
• portable compact power plants;
• water pump.

These are just the most common and popular options. More detailed information about some transformations will be presented below.

The simplest upgrade

A sawmill is a homemade chainsaw that does not require much effort, but it can greatly facilitate the process of sawing logs into boards. We can say that in this case the saw in a somewhat modernized state is used for its intended purpose.

It is almost impossible to dissolve a long log on weight. The problem can be solved elementarily. This will require, firstly, a metal frame on which the saw will be rigidly attached. Secondly, the rail track along which the workpiece will be fed.

Moped

This transformation is somewhat different from that described earlier, since the very purpose of the device changes here. The motor of the tool is proposed to be used not for cutting anything, but for moving in space. Of course, homemade products from the Ural chainsaw will by no means be able to compete in power and speed with the motorcycle of the same name, but the moped will turn out to be quite efficient.

The owners are very proud of this vehicle. It's not about the running characteristics of their offspring, but in principle. A moped assembled “on the knee” shows the skill and thriftiness of a person, demonstrates to everyone his

The base of such a vehicle is on the frame of which the motor is mounted from the same ancient chainsaw. Best for energy transfer

Some enthusiasts go a little further in their research and take a mountain bike as the basis for a homemade vehicle. In this case, it will be possible to control the speed of movement. To do this, you just need to equip the moped with a gearbox.

Motor cultivator

You can list for a long time in which areas of activity homemade products from people with land are used in our country, which has led to the fact that such "masterpieces" are quite often used in summer cottages as motor cultivators.

As far as this device is useful in everyday life, it is so easy to assemble it. To do this, you only need a transmission system consisting of a pair of gears. With the help of it, the energy of the engine will be transferred to the drive wheel, which sets the working mechanism in motion. The disadvantage of this design is the small power, which will not be enough to plow virgin soil, but it will be enough for a small well-groomed area.

Power station

A portable power plant capable of providing power to those in the most remote places from civilization is one of the marvels of engineering.

Such a homemade chainsaw can be designed by a person who is at least a little versed in mechanics and electrical engineering. The parts list should look like this:

• chainsaw;
• gear reducer;
• drive belt;
• metal bar;
• generator;
• Remote Control.

snow blower

Since winters in the middle lane are very severe, and there is no shortage of snow, everyone dreams of enlisting such an assistant as a manual snow blower. This is a completely doable task. It's all about the principle of the engine, which is based on the fact that its rotational energy can be used for any purpose.

A chainsaw with a power of 3 kW or more can be converted into a snow blower. The whole trick will only be how to mount the screw assembly. Its blades must be made of a durable, but at the same time sufficiently light and elastic material, such as rubber. Further actions do not differ at all from what was described in other paragraphs. With the help of a chain, the motor is connected through a gear pair to the screw assembly. From a practical point of view, it would be correct to use sledge skids instead of wheels, and take a curved large-diameter water pipe as a snow thrower.

In the hands of craftsmen, an ordinary chainsaw, originally designed for sawing wood, becomes a truly multifunctional device. At the same time, the breadth of its application is simply amazing in its diversity. On sale there are various types of special nozzles that greatly expand the capabilities of chainsaws. These include the following attachments: a petrol cutter, a scorcher, a pump for pumping water, a motor, a brush cutter, a snow blower, and others. But, despite this, many craftsmen remake chainsaws on their own, using improvised materials. Do-it-yourself homemade chainsaws can be made by almost anyone who is more or less versed in technology.

The principle of rework

At the heart of almost any homemade chainsaw is its use as a universal drive that can be used for a huge number of different devices. The scope of their use is very wide: cutting stone and metal, pumping out water, cleaning snow, drilling wells and holes, driving, moving various objects, swimming and even flying.

Realize the potential of a chainsaw with a variety of attachments and attachments. At the heart of any alteration is the simple principle of engine power take-off: the device necessary for the master is connected to the output shaft. The presence of a powerful motor, compact dimensions and relatively light weight of this tool, autonomy and the ability to work in almost extreme conditions make its possibilities truly limitless. Equally important is the practical design of the clutch, which protects the components and systems of the saw from damage and overload. A tool made from a chainsaw is distinguished by its tightness, so it can be used in almost any position.

What can be made from a chainsaw

All homemade products can be divided into 2 groups:

• the simplest devices (grinder, ice drill, pump, winch, walk-behind tractor, outboard motor, bicycle, moped);
• more complex mechanisms and objects (sawmill, snow blower, snowmobile, snowmobile, power plant, helicopter, solid forged knife).

For the manufacture of all of the above devices, you can use various brands of chainsaws. When choosing them, one should take into account the necessary power for the normal operation of the alteration. Most often, for the manufacture of various devices, the following brands of chainsaws are used: Friendship, Calm, Ural.

The simplest homemade chainsaw

Below are the various options for devices made from chainsaws. Anyone can use these ideas in their household. From a chainsaw with a small amount of additional materials, you can make:

Bulgarian. The main system of such a device is a bearing assembly with a shaft. At one end, a driven pulley is installed, which rotates with the help of a V-belt. On the other, a mandrel for cutting wheels is fixed. Depending on their brand, such a grinder can cut stone, metal, brick and other building materials.

ice drill. For good operation of the device, the screw speed should not be high, so it is necessary to use a gearbox made in the form of a worm or V-belt drive. Such a device can be used in the construction of a foundation of screw piles and for other earthworks.

Water transfer pump can be used for watering the garden, emergency water supply, drainage of reservoirs or flooded basements. This nozzle is a simple centrifugal pump, equipped with a bracket to attach to the saw and a pulley that drives the pump turbines.

Winch, which uses a chainsaw drive. The traction force of such a device directly depends on the power of the saw motor. When using an additional block, it can be significantly increased. This device is equipped with such additional parts as a tap-off block, hooks, belts, anchors.

Outboard motor from a chainsaw- a great alternative to buying an expensive engine. To ensure movement of 20 km / h, it is enough to install a home-made outboard motor with a gearbox (gear ratio 2: 1) and a 3-blade propeller with a diameter of 210 mm on the boat. At the same time, fuel consumption will be only 1 liter per hour of engine operation.

Motor cultivator almost anyone can assemble from a chainsaw. This requires a transmission system (2 gears). With its help, the energy of the motor is transferred to the drive wheel, thanks to which the working mechanism is set in motion. Of course, such a cultivator is of little use for cultivating a huge field, but its power is quite enough for a personal plot.

Chainsaw moped. For such a vehicle, you will need a base, for example, an old bicycle. A chainsaw motor is attached to its frame. As a rule, a gear is used on such a vehicle. If a mountain bike is used for conversion, then a gearbox will be needed to control the speed of movement.

For the manufacture of the following devices, the master needs some technical knowledge and experience with various mechanisms and materials. From a chainsaw using various components, you can create the following homemade products:

Chainsaw sawmill, which can be done with a metal frame. A chainsaw is rigidly attached to this frame. Workpieces can be guided along the rail track. There are other options for sawmills. So for a device designed for longitudinal sawing, you will need an adapter attached to the tire located at its base and a guide that sets the direction of movement of the adapter. The guide is installed on a board attached to the sawn log. With the help of such a sawmill, logs can be divided into 2-4 parts.

Chainsaw portable power plant is able to provide energy in any places remote from the power grid. To create it, the following components are needed: a gear reducer, a generator, a metal bar, a drive belt, a control panel. Powerful saws Druzhba and Ural are most suitable for such a device.

Homemade snow blower can be made from a saw whose power exceeds 3 kW. For it, it is necessary to mount a screw assembly with blades made of durable but elastic material. The chain connects the motor to the screw assembly through a pair of gears. You can attach both wheels and skids to the snow blower. Any large diameter pipe can be used to throw snow.

Homemade snowmobile from a chainsaw its design is a little more complicated than a sawmill. The snowmobile consists of a frame, engine, track and steering. He also needs skids for movement. To create it on the steering wheel, you need to take out the gas and clutch. You should also consider a shock-absorbing suspension system of the carrier frame. Since the chainsaw does not have a transmission, the clutch on a homemade snowmobile is centrifugal. A poly V-belt and a chain are also used. For the steering mechanism, you can use the parts of an old bicycle. It is being redesigned so that the central axis moves the turning skis of the thrust. To enhance traction, a traction gear is installed on the caterpillar drive shaft. Engine power must be at least 5 hp.

Snowmobile from a chainsaw much easier to make than a snowmobile. A large propeller driven directly by the chainsaw's engine provides the driving force. A serious limitation on the use of such snowmobiles due to their insufficient cross-country ability is the low power of the chainsaw engine. For trips on snowy fields, an engine with a power of at least 12 hp is required.

Helicopter knapsack type from a chainsaw. Such an aircraft can take to the air only when at least four engines with a total power of 20 hp or more operating in a coordinated mode are used in its design. It will not work to make it from one chainsaw. Using such a homemade device can be life threatening.

Can be done by people familiar with blacksmithing. To do this, first of all, the old chains are divided into pieces, which are then welded into blanks. They are heated in a furnace to 850°C. The blanks are pressed until they get rid of the voids between the links. Next, the metal is subjected to forging until the workpiece is given the required shape and strength.

What did you do with a chainsaw?

A moped, along with a bicycle, is a very convenient vehicle. Moreover, it drives faster than its older brother, thanks to the built-in drive. The ability to move quickly without much effort - isn't this the dream of every cyclist? It is quite realistic to bring it to life - to supply your bike with a gasoline engine or an electric motor.

An assembled moped from a bicycle is a fairly common occurrence in rural areas or regional towns. It is there that they like to put innovative ideas into practice, in particular, to make smart and economical transport out of an ordinary old bike. Have you noticed a similar interest? Then it's time to get down to business!

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;
• transmission belt or chain;
• drive cable;
• fastening clamps.

Recommended power - 2 liters. with., and the engine capacity 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 from a chainsaw or lawn mower.

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

• on the top tube - the battery;
• the junction of the lower front and seat tubes - the engine;
• next to the engine is a gas tank.

At the next stage, you need to make pulleys - special transmission units through which the engine power will be transmitted to the rear wheel. The starting material for pulleys can be small wheels with external barriers, the size of a CD. Mandatory conditions are the strength of the material and reliable fastening.

Do-it-yourself pulley installation on a bicycle:

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

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

So, the transmission is ready, now let's move on to connecting the engine:

1. The working body of the motor is connected to the battery.
2. Assemble the “ignition” mechanism: an ordinary brake handle is fixed on the steering wheel, then it is connected to the engine body through a cable.
3. Set the tension so that the motor starts freely through the handle.

Option 2: we assemble a moped with a gas 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;
• tools.

Since here we are going to get a real moped, the frame must have increased strength and weight. Also, mopeds have a slightly different frame design, which may require a little redoing.

Wheels from a moped are put on the frame. You will need to change the design of the fork, as the width of the wheels will be wider than the distance between the dropouts. If possible, install shock absorbers on the fork.

The power unit of the moped should be carefully sorted out and replaced with all defective parts. The propulsion system will require a separate place, for this a welded metal platform at the bottom of the frame would be a good option. The engine and fuel tank are fixed on the site with metal fasteners. 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 during movement.

1. Remove the pedals and chainring from the bike frame.
2. Install sprockets on the rear wheel from the moped and the engine shaft. A star on a wheel of a larger diameter.
3. Put the rear wheel on the frame.
4. Use the chain to connect the stars.

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

Brakes. If only one brake (for example, the front one) can be enough for a bicycle, then 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 bicycle-based moped will look like this:

Converted bike

Since an engine-equipped vehicle moves faster than a conventional bicycle (this is what the alteration is thinking of), for safety reasons it is necessary to put lighting devices on it. Personal protective equipment - helmet, knee pads and special shoes.

How to make an electric bike

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

Installation options - 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 changes to the classic transmission. And if you want, you can even put two motor-wheels. Installing is easy enough, provided the bike itself allows it. However, a bike with such wheels can be attributed to a moped with a big stretch.

Motor wheel kit

An electric moped is a completely different matter, that is, an analogue of the one discussed above. Of course, an exhaust pipe will not be needed here - this is a plus both in terms of reliability and overall weight.

It will be problematic to assemble an engine from scratch at home, so let's look at how to install a finished motor shaft.

Progress:

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

Speed ​​bike with electric motor

The location of the battery is on the lower front tube of the frame or on the trunk. The scheme of the electric motor:

1. When the electric motor is turned on, the rotating roller engages with the rear wheel tire, pushing it.
2. Through the pulleys and the front sprocket, torque is transmitted to the transmission.
3. Gear shifting causes a change in output torque. In this case, the speed of rotation of the roller is kept constant.

DIY electric bike:

Optionally, you can connect a second shaft to the front wheel by linking it to the driven pulley of the main gear.

The engine allows you to reach the optimum speed faster and hold it longer. A bicycle-based moped is a budget option to become the owner of a faster and more powerful vehicle. The transformation of a bicycle into a moped in most cases does not make irreversible changes to the design, so it is possible to return everything to its place.
