✅ How to make a moped from a chainsaw

Chainsaw moped

At first glance, a moped and a saw are absolutely incompatible things that cannot interact in any way. But this is wrong, and numerous craftsmen have proven that making a moped from a chainsaw is quite possible. But there is little to be done; this unit also drives and transports its owner. The speed, of course, is not very fast, but it’s still better than walking. You can use a bicycle as the basis for the design or do everything completely yourself. The bike motor amazes with its endurance, but this is what everyone expects from time-tested saws.

The older generation is familiar with self-propelled structures in the form of a bicycle with a motor. It is difficult to classify this equipment as mopeds, but they no longer fall into the category of bicycles. A kind of “middle link”. A significant advantage of such a unit is low fuel consumption and the ability to drive without a license. You can’t ride it on public roads, but you can drive along rural streets and alleys.

The frame has undergone changes, which have been extended to accommodate bicycle or other wheels, depending on what is available. A fuel tank is also attached, a motorcycle seat is installed, and a headlight is attached for driving in the evening. A water system has been developed to cool the bicycle motor. This was done to prevent the engine from overheating quickly and losing power.

Engine

The key component of a homemade snowmobile is the engine. Unlike other parts, such as a bus or chain, this unit must function without the slightest glitch. Otherwise, the car will remain motionless or stall at the wrong moment.

Therefore, the issue of choosing and installing an engine must be treated with full responsibility. If you want to choose an engine from an imported chainsaw, it is recommended to choose the “Calm” model.

The next, no less important, unit of the system is the gearbox. It also plays a key role in the trouble-free operation of the snowmobile.

Asterisks

The right tip has a special groove for mounting chain sprockets. We are talking about a caterpillar shaft sprocket, which is secured with a nut. To implement this action, an appropriate thread is made on the tip.

The shaft tip has similar dimensions, and its fastening is carried out in exactly the same way as the shaft sprockets.

The sprocket with the largest number of teeth is installed in the first stage of the transmission. The Ural power plant has up to 38 teeth.

Steering

To produce a functional and comfortable self-propelled vehicle that can be easily controlled by an inexperienced driver, you can use any available steering wheel, including a bicycle one. In this situation, you will need to provide manual control of the speed, which requires some effort. You can avoid wasting time by using a steering wheel from a moped or scooter, which is already equipped with a power control unit. In this case, the design will become as comfortable and reliable as possible.

Which saw is suitable to use?

The most optimal gasoline saws for conversion are “Druzhba”, “Ural”, “Shtil” and similar models with a large power reserve. It is this parameter that you should pay attention to when converting a bicycle into a moped. Some German chainsaws with high power lend themselves very well to conversion. The device should be selected with a power of at least 2 hp. and engine volume no more than 50 cm3. Bicycle motors from such units are the most durable.

In order to make a motorbike, it is not necessary to have a special technical education, but it is desirable to understand diagrams and drawings, as well as have skills in repairing garden equipment. Skills in working with a welding machine will not be superfluous.

What details are needed?

In order to assemble the motorbike structure you will need the following materials:

chainsaw motor
bicycle wheels 2 pcs.
tank, headlight, seat from a motorcycle or other suitable unit
spray paint cans 4 pcs. and masking tape
metal pipe 16-20 mm.
cable
chain
cycling stars
front and rear bicycle forks
axis
hose
plastic bottle
IV
steering wheel
throttle handle

It should be noted that on the modern market there are ready-made kits that include all the necessary parts for making homemade products. But the question here is price. If you want to save money and use unnecessary parts lying around in the barn, you will have to try on your own.

Making a walk-behind tractor from a chainsaw with your own hands

According to the owners of land plots, who have already experienced all the features of handicraft motor vehicles from a gasoline saw, assembled with their own hands, “Druzhba” demonstrates excellent results after modernization. With the right choice of power plant for a homemade unit, it works no worse than its industrial prototypes.

The absolute advantages of this device are:

high power, reaching up to 4 horsepower in some samples;
lightness - a small mass will not make the unit heavier and will increase its mobility;
compact size - a small engine does not require reinforcement of the frame, which reduces the financial costs of its manufacture;
economical consumption of fuel and lubricants;
performance, which is determined by readiness for prolonged loads;
possibility of using all kinds of fuels and lubricants;
functioning in a completely autonomous mode;
applicability for various types of work.

The assembly procedure depends on the drawing used and may vary, but the main points of assembly include the following activities. The frame is assembled in accordance with the drawing.

The work process is organized as follows:

we take a metal pipe with a cross-section of at least 20 mm and bend it so that the overall appearance looks like 2 spars, the end of which is directed upward;
a motorcycle handlebar is welded in the rear area of the spar;
we strengthen the base with crossbars;
We electric weld the support platform for the battery to the rear bends of the side members.

Further work continues on the following points.

Now we mount a specialized flange, with the help of which the shaft will be fixed to the main structure of the unit from a gasoline saw.
We buy sprockets from a UAZ car at the used parts market. Through them, ground clearance (ground clearance) will be formed between the ground plane and the connecting wheel beam.
We take bearings with a 30 mm diameter. We fix them to the main bridge.
The gearbox, equipped with a gearbox, is assembled from a motorcycle engine.
The wheels and cutters of a handicraft cultivator are installed on a metal pipe of the required diameter.
Due to the fact that the walk-behind tractor has a low speed, a forced-type cooling system is required. The simplest solution is to install a fan. And so that the air flow is directed towards the cylinder, a protective coating is used. It could be an old motorcycle gas tank.

Assembly principle

The first thing that attention is paid to is the design of the frame, which is made of pipe and on which the power unit will subsequently be placed. Then the tank, headlight and wheels are installed. If you are using old parts, you must first clean them of rust. This is especially true for seams. After the initial stage is completed, the frame is covered with several layers of paint. Be sure to dry each layer thoroughly to avoid corrosion. As a recommendation, it is best to use spray paint to avoid smudges. You can paint not only the frame, but also the wheels, after sealing the rims with masking tape.

Moped made from a chainsaw. Tips and tricks

A DIY chainsaw motorcycle is a solution for those men who don’t want to spend money on a car and its subsequent maintenance and who don’t like pedaling a bicycle. In this case, an excellent way out of the situation would be a moped from a chainsaw and a bicycle, which you can assemble with your own hands in the garage, having purchased some of the necessary, missing parts and spare parts. The remodeling process itself is not particularly difficult.

Before starting assembly or if you have 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 the basis for a future moped, you can choose an old bicycle that you want to breathe new life into. You will also need a chainsaw to install the motor on the bike. Thus, you will get a motorbike that you can upgrade: repaint it, install wider wheels, change the handlebars and do other procedures that will make your homemade bike more like a motorcycle.

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 chainsaw motor to it does not require any special skills of a mechanic or engineer. If you are new to this business, then numerous drawings of a moped made from a chainsaw, as well as educational video reviews, will help you. Also, not every man has everything he needs in his garage to make a motorbike from a chainsaw with his own hands. Therefore, before assembly, 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 entire kits that 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, suitable power, fasteners, battery, transmission belt, cable, etc.

Speaking of tools, you will really need all the popular types of auto mechanic kit components: screwdrivers, pliers, wrenches, wire cutters, etc.

Assembly instructions and drawings of a homemade moped

Tips and tricks

Many users insist on paying attention to how the belt is held on the wheels. The degree of its fastening affects the transmission of force 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 removed from the chainsaw should be in full working order. Otherwise, spend a little more time assembling the moped yourself and rebuilding the engine. Try to fix failed parts or completely replace them with new ones.

Design, drawings, diagram

To create a homemade moped from a chainsaw, you usually do not need any complex diagrams or drawings. The engine is mainly mounted on the frame; some craftsmen install the engine on the rear trunk. Let's consider the first option, which most closely matches the standard moped model. From the chainsaw we use the motor and gas tank, which are placed side by side - at the connection of the seat tube and the front down tube. The best place for the battery is on top, closer to the front of the frame.

Since a chainsaw moped is driven by transferring force from the rear wheel to the front, the design must include transmission pulleys (belt drive) or gears (chain drive). The motor shaft is connected to the front pulley, and the rear pulley is mounted on the rear wheel hub. The pulleys are connected with a strong belt and the tension force is adjusted very correctly. Similarly, all actions are performed when installing a chain drive with gears.

Then the transmission is installed and the motor is connected, which is connected to the brake lever. The engine is connected to the battery, the cable is set correctly. As a finishing touch, the craftsmen paint the new product and give it a beautiful modern design.

Old chainsaws are some kind of inexhaustible source of inspiration; their parts and components are literally disassembled for spare parts when assembling homemade products. When repairing a motorcycle, they use ignition from a chainsaw, which, according to reviews from popular designers, is much more efficient and durable than the original magneto.

Craftsmen use the engine from a chainsaw in a fantastic way to create other home-made vehicles: a scooter with a motor from a chainsaw, a motorcycle with a saw engine, all kinds of versions of motorbikes, motorbikes on three wheels with a motor, scooters from a bicycle and a chainsaw, go-karts, tricycles, absolutely unique ATVs and a great variety of simply unimaginable designs.

Reviews of a homemade motorcycle made from a chainsaw

Many men, when they want to improve an ordinary bicycle, wonder how to make a bicycle with a chainsaw motor? The answer is very simple: this requires a working engine, the above parts, patience, drawings and free time. As a result, as many reviews say, you get a comfortable and maneuverable vehicle that does not require large financial investments and complex maintenance.

Oleg, 67 years old, Rostov

“I have a lot of old chainsaws and have always been interested in DIY modifications. Two years ago I decided to make sure for myself that you can assemble a scooter with a chainsaw motor with your own hands and at the same time get a working moped on the go. I took a Druzhba chainsaw, wheels from an old motor scooter, a frame from a moped and some other parts from the list. I had to work hard on the drawings, but it turned out to be a good vehicle at minimal cost. The speed, of course, is not racing, and there is a lot of noise. But overall a comfortable and interesting experience.”

Igor, 32 years old, Kherson

“I had a lot of free time and decided to assemble a motorbike with my own hands. I read a couple of articles, studied the structure and built a plan in my head on how to make a motor bike from a chainsaw. I bought the necessary spare parts and components for the scooter, found the drawings, got my eldest son involved in the work, and within a week they assembled a cool motorcycle. A homemade moped goes quite fast, you can always improve it in some way because you know its design completely.

How to Make a Tricycle From a Chainsaw Ural

ability to travel long distances

If small luggage is already a luxury for a regular motorcycle, then you can load a decent amount of stuff on a motorcycle that will be useful on the road. Since you can make a tricycle from a motorcycle using an engine from a car, it is easy to achieve more power and more body space. Unfortunately, it is rare to see trikes on the roads, and this is not because there are few enthusiasts, but because the registration of homemade cars. quite a complex and lengthy process. Converted Ural motorcycle and trike using the rear axle of a car or engine. different things for regulatory authorities. On the other hand, buying knitwear with documents, factory or processing is quite problematic, also due to the high cost. If you want to test your strength as a motorbike, make a tricycle from the Urals.

Beginning of work

The trick assembly must be prepared in advance. You will need to find a dismantled ZAZ-968 and a Ural motorcycle in decent condition. You will need an engine from ZAZ, from the Urals. most of the components. You will have to produce the frame yourself, and this is the most difficult stage of the entire project. As a result of manipulation, changing a Ural motorcycle on a tricycle can turn into a presentable, powerful vehicle, no worse than its factory counterparts.

The frame plays the role of a connecting line on which all the parts will be installed. It must be reliable and comply with the drawings. Nuggets that can be accurately measured up to 5mm to produce similar items. units, if you doubt your abilities, it is better to trust the work to professionals. Before installing the parts, take an hour and measure the frame with a tape measure, check the location of the holes and latches.

Review of a tricycle with a chainsaw Ural

crazy chair made from all the junk that was lying in the garage, here's another thing.

If you don't know how to assemble a tricycle from the Urals. strictly follow the drawings. Typically the top beam is used to secure the rear shock absorbers. Glasses welded to it will achieve a good level of comfort. Car-like shock absorbers will respond reliably to changes in road surface. Just weld a square or round pipe in the stock. this won't be enough. Ferrous metal reinforcing scarves must be used and can be welded well. A do-it-yourself trike from the Urals can be used not only to satisfy your love for a hobby, but also as a work horse on a farm. Given a target, such a trick can have a lifting capacity of several hundred kilograms . It will be necessary to install not only the engine, but also prepare a place for installing the gearbox. At the same time, running ahead, there will be more problems, since there is no ready-made structure that needs to be removed, but to do

the block itself is very complicated.

It is also important to remember that a do-it-yourself tricycle from the Urals has a shifted center of gravity back. This is due to the installation of the power supply. A common problem is that at high RPMs and suddenly releasing the clutch, the bike can end up on its hind legs. Therefore, if you can shift the scales to the front wheel, it is better to use it.

The frame-mounted engine requires little to no finishing. Main. prepare the ZAZ-968 engine so that it works flawlessly. The exhaust system will also need to be ordered. Firstly, all bikers are simply delighted with the big and bright chrome parts, and secondly, you may not like the sound of the engine. A tricycle from the Urals can have an oil cooler or water cooling.

The shift lever is usually located on the left, so the driver can control the gas with his right hand. Creation of a rotary mechanism for gear shifting. this is a creative task. In general, it would be wiser to order this mechanism from an enterprise or factory, pay a certain amount and not waste a huge amount of time. It won't work the first time anyway, but completion. business complex. Before making a tricycle from the Urals, it is worth considering all the dimensions of the future unit. For example, remove the front fork. However, it is not difficult to remake it with certain dimensions, but the length of the fork will depend on the angle, which is adjusted by the glass on the frame. Of course, it will be possible to reduce it upon request, however, increase it. No.

Moped from a chainsaw: assembly photo, test video

Homemade moped from a Ural chainsaw made in a couple of days: photos of step-by-step assembly, as well as a video of testing the moped.

The author had a chainsaw lying around at home, since there was nothing really to cut, this craftsman decided to make himself a moped out of it. In fact, he succeeded, as evidenced by photos of the homemade construction and a video where the author personally demonstrates the capabilities of his moped.

To implement the plan, the following materials were needed:

Engine from a Ural chainsaw with a volume of 109 cm³.
Carburetor from Minsk.
Pipe with a diameter of 30 mm (for the frame).
Front fork from the Stork bicycle.
Wheels with a diameter of 265 mm from a garden wheelbarrow.
Sprockets with 41 and 13 teeth from the Alpha moped.
Bicycle disc brakes.
The rear wheel hub was machined from aluminum.

Next in the photo is the actual assembly of a moped with a chainsaw engine.

First of all, the author bent water pipes and used a welding machine to weld a moped frame.

Then I installed the engine on the frame.

I machined two bushings for the rear wheel from aluminum, attached a sprocket to one side of the wheel, and disc brakes to the opposite side.

Mounted the rear wheel to the frame.

I installed the front wheel, a bicycle handlebar, a gas and brake handle, a seat, and an ordinary plastic bottle with a hose was attached as a fuel tank. I welded the footrest from a piece of angle iron.

Despite its miniature size, the homemade moped reaches speeds of up to 50 km/h, as evidenced by the video provided by the author.

DIY FRIEND

Dear visitors to the site “ Self-Made Friend ”, from the material presented you will learn how to make a moped yourself from a “Friendship” chainsaw... Today, the popular topic of creating various bikes and bicycles with engines from a chainsaw, where they mainly use domestic samples of the “Druzhba” or “Druzhba” brand Ural". But the author wanted to make something more elegant than just a homemade one, so that it would look more like a real moped or chopper. I already had experience in assembling a moped last year, but I wasn’t very happy with the appearance. The new model will have bicycle wheels and, to give a cool look, a tank, headlight and seat from the rare Minsk-103 motorcycle will be installed. The author also developed and implemented a water cooling system for the chainsaw engine, it consists of the following: a bottle of cold water is attached to the frame and 2 hoses go from it, one upward for air intake, and the second is connected to a dropper and through it drip irrigation is carried out on the cylinder head, thereby cooling it. The bottle itself is removable and fastened with rubber bands to make it easy to remove and refill with cold water. The dropper can be opened and closed, you stand still, closed it, went and opened it)

Let's figure out what exactly is needed to create a moped from the Druzhba chainsaw

Materials

chainsaw engine
bicycle wheels 2 pcs
tank. headlight, seat from the Minsk 103 motorcycle
pipe 16-20 mm
bottle, hoses, dropper (for water cooling system)
chain reducer
spray paint

Tools

welding machine
Bulgarian
sandpaper
screwdriver
set of wrenches
pliers

Step-by-step instructions for creating a moped from a Druzhba chainsaw with your own hands.

The author's first experience)

A dream and a model from which the moped was copied.

I sketched a sketch of the future moped.

I welded the frame and tried on bicycle wheels.

Painting the frame, wheels and spokes.

I installed the engine from an old moped.

But soon the engine died and a new one had to be installed; the author had it in stock from the winter)

Then the author encountered a problem after 20 minutes of operation, the engine overheated and stalled, so he changed the gear ratio on the gearbox.

The engine did not stop heating up and the author came up with the idea of water cooling the engine. Why I took a plastic bottle and connected 2 hoses to it, one up for air intake, and the second connected to a dropper for supplying water to the cylinder head of the Druzhba chainsaw
