Install a chainsaw engine on the bike

DIY bike with a chainsaw engine

If you want to equip an ordinary bicycle with a motor, you can use a chainsaw.

When self-fastening, you must adhere to the following rules:

  • There should be no cracks in the gas tank to avoid fuel leakage;
  • It is necessary to observe the indicators of the optimal load;
  • All cables, chains and pulleys must be installed firmly and securely to avoid slipping or breaking;
  • The motor must be attached exclusively to certain areas (frame or engine directly);
  • When choosing a gas tank, there are maximum permissible indicators: weight up to 6 kilograms; volume up to 50 cubic centimeters.

Benefits of using a chainsaw to build a bike

Required materials and tools

Basic materials and tools for work:

  • Metal objects (chains, nuts, bolts, washers);
  • Handy tools for bracket installation;
  • Belts;
  • Bicycle rope;
  • Fuel tank equipment container.

Step-by-step instruction

  • It is necessary to establish a connection between the wheel and the motor. For such purposes, additional parts (pulleys) are installed on the wheel and connected directly to the chainsaw. A belt or chains are used to transmit power (it is necessary to look at the situation). The main rule here is to provide that such a structure does not fly off;
  • At this stage, you need to take care of the centrifugal force. A chainsaw or bicycle ratchet can be used for this purpose. Thanks to the second option, it will be possible not to press hard on the pedals, but at the same time maintain the speed of movement for a certain period of time;
  • With the help of a hose, it is necessary to create a connection with the gas tank, and also firmly fasten it near the engine or frame;
  • To install the ignition, you need a wire and a special switch. With its correct location, it will be possible to turn off the engine at any time;
  • You will also need a throttle stick to switch the engine. A bicycle cable can be attached to a special carburetor flap.

Acceleration and noise

With a self-made fastening of the engine from a chainsaw to a bicycle, it is possible to get a speed of up to 50-60 kilometers per hour. Acceleration is simple and easy, and during the ride there will be no characteristic smell of gasoline.

The speed will directly depend on the performance of the motor. Its activation can be accompanied by strong and unpleasant sounds.

There are 2 options for solving the problem:

  • Move with loud sounds (hum, creak);
  • Install a special muffler, with which the motor will become almost silent.

It turns out a powerful and quick means to get to a summer cottage or fishing place. What is a bike with a chainsaw engine?

Chainsaw karting. assembly features

To assemble this homemade product, you will need to remove the handle, fuel tank, cutting elements, a gear rack and a built-in cable connecting the throttle handle and the engine from the chainsaw used in the household.

In the future, the operator will have to:

  • Remake the standard chainsaw sprocket. To do this, it is necessary to carefully grind off all its teeth to arbitrary sizes, since the outer diameter of the part does not play a big role. To the resulting workpiece, you will need to weld a pre-ground Minsk asterisk;
  • Arrange a place for attaching the power unit to the subframe. To do this, drill 2 small holes in the cooling jacket, each of which should be about 8 mm in diameter. They need to be drilled in standard holes, each with an initial diameter of 6 mm;
  • Assemble a subframe that is strong and as vibration-resistant as possible. For its construction, sheet 3-mm steel is suitable, to which 2 corners with dimensions of 35 × 35 mm need to be welded. In the corners, you need to pre-drill holes with an exact diameter of 8.5 mm. they will be required for the fixed fixation of the power unit from the chainsaw. In the opposite part of the steel plate, it is necessary to vertically weld a metal corner with dimensions of 35 × 35 mm. it will be necessary to install the gearbox used. In addition, a 10 × 1.5 mm type M nut will need to be installed on the plate to be able to tension the chain;
  • To install the gearbox, you need to turn it over the other side;
  • Weld the rails to the back of the steel plate. They can be made in advance from halves of metal pipes with dimensions of 30 × 2 mm;
  • Install the steel plate with the parts welded to it on the chassis taken from the old AKU 89 go-kart;
  • Equip a homemade chainsaw with a seat, steering wheel and braking system. If, during the assembly process, it turns out that the muffler from the internal combustion engine is directed at the driver, then it will need to be shifted to the side, or lengthened with a piece of metal pipe.

A ready-made homemade product will be able to accelerate to 60-80 km / h, carrying one adult passenger on board.

How to put a chainsaw engine on a bicycle?

After assembling the frame and organizing the transmission of torque, the moped will need to be equipped with an engine. For its installation, it is best to prepare a separate metal platform that will be welded to the support frame above the rear wheel. Several holes will need to be drilled in the platform to secure the power unit. This will allow the operator to unscrew the screws and remove the internal combustion engine from the moped for its further installation on the chainsaw.

After installing the power unit, it will need to be connected to the transmission bodies of the generated torque. To do this, you will need to connect a metal throttle valve and a standard fully serviceable clutch for the made moped to the lever of the built-in ignition system. In this case, the tensile force of the cables used must be calculated so that when starting the engine instantly turns on and begins to spin the drive wheel.

How to make a moped out of a bicycle and a chainsaw?

To assemble homemade mopeds from a chainsaw, manufacturers will need:

  • wheels, fully assembled braking system, shock absorbers and exhaust pipe. these must be removed from the old moped;
  • a welded frame from an old unused bike;
  • drill, angle grinder, welding machine and other equipment.

The algorithm for further work on assembling the moped should be as follows:

  • If the designer could not find a ready-made frame from an old bicycle, then you need to make it yourself. To do this, it is necessary to weld metal pipes together so that a triangle is formed. To the finished moped frame, you will need to additionally weld 2 more pipes, which will give the structure rigidity and stability. Next, you need to fix a soft seat and steering wheel to the frame;
  • At the next stage, the designer must organize the transfer of the force created by the engine from the chainsaw to the moped’s movement organs. To do this, it is necessary to remove the front sprocket and pedals from the finished bicycle frame in advance. After that, sprockets will need to be installed on the shaft of the engine used and on the side of the rear wheel of the moped;
  • Then the rear wheel must be installed on the support frame and the two stars must be connected with a chain.

For a stable transmission of continuous power from the motor to the installed drive wheel to the moped from a chainsaw, it is necessary to mount a gearbox pre-filled with new transmission oil.

Chainsaw vehicles. what are the pros and cons?

When self-assembling 2- or 4-wheeled vehicles on the basis of an economic chainsaw, the manufacturer receives several rather important advantages:

  • the manufacture of the unit makes it possible to save money. Of course, during assembly, you will have to spend money on individual parts or whole work units. Nevertheless, these expenses are incomparable with the purchase of branded equipment;
  • assembling vehicles with your own hands will allow you to get a reliable and fairly passable unit that does not require frequent special maintenance or complex repairs;
  • in the manufacture of vehicles, the designer can create any of the selected modifications: go-kart, ATV, moped or scooter from a chainsaw.

Chain saw bike

The only drawback of its kind is the need for skills in operating an angle grinder, drill, welding machine and other types of garage equipment. Otherwise, it will not work to assemble a moped or other type of equipment.

DIY bike with a chainsaw motor. assembling a moped, go-kart, scooter and ATV

Many gardeners use a chainsaw for its intended purpose, not suspecting that it can serve as material for making some useful homemade products with their own hands. It can be used as a basis for assembling a 2-wheel moped or 4-wheel go-kart. The advantages of self-manufacturing of these vehicles are obvious. high savings and the ability to get high-quality equipment for active use in everyday life.

What motors are suitable for assembly?

To answer this question, you need to select in advance the type of equipment that the manufacturer wants to assemble.

There may be several options:

  • scooter. small homemade product. The hardest part is the niche for the user’s feet. The rest of the elements can be made of light steel or aluminum. Power units with a capacity of about 3. 4.5 liters are best suited for assembling a scooter based on a chainsaw. from.;
  • karting is a small device designed for high-speed movement on a flat asphalt or concrete surface. The estimated engine power for the assembly of karting should be approximately 4. 5 liters. from.;
  • a moped is a medium-sized vehicle with a sturdy, stable frame at its core. For the manufacture of a moped, motors from chainsaws with a capacity of 5. 6 liters are suitable. from.;
  • an ATV is a relatively large vehicle that is assembled from sufficiently strong and heavy parts. A chainsaw with a rated power of at least 6 liters is suitable for assembling an ATV. from.

Regardless of the technology the manufacturer wants to get, the DIY engine must be in perfect working order. It is best to pre-clean or completely replace all filters in its design, as well as adjust the carburetor and ignition.

How to make a scooter from a chainsaw?

For self-production of a scooter based on a utility saw, the designer will need to prepare 3 mm steel plates, as well as metal pipes and corners. The engine from the gasoline tool must be completely serviceable and serviced. Assembly order:

  • First, you need to make a support frame. For its assembly, profile pipes are well suited and a steel plate is pre-treated against rust. Scooter wheels from a pre-disassembled chainsaw can be taken from an old garden cart;
  • To transmit the torque generated by the power unit, a chain and a star are required. To install the second part of the chain, you need to grind a small metal tensioner;
  • The scooter driver will fill the fuel mixture into a remote tank, which must be installed a few centimeters above the engine;
  • The homemade brake system will be disc type. Parts from an old moped are suitable for its assembly.

As a result of the work done, the designer will receive a unit capable of speeds of about 30. 40 km / h.

Benefits of using a chainsaw to create a moped

Self-assembly of a bicycle with a motor from a household chainsaw gives the manufacturer a number of important advantages.

A gasoline scooter from a chainsaw is quite easy to repair. Provided the correct sequence during assembly, the manufacturer of the unit has free access to frequently replaced parts of the moped, which saves time by repairing it.

DIY bike with a chainsaw motor

Due to the high power and endurance of their engines, most modern chainsaws are successfully used for conversion into various household appliances. One of them is a chainsaw moped. This vehicle will allow you to successfully cover distances up to 15 km long, while showing, at the same time, a fairly modest fuel consumption.

DIY bike with a chainsaw motor

Immediately before making a moped from a bicycle and a chainsaw, its manufacturer will need to carefully prepare for work.

For the alteration you will need:

  • gasoline engine. the speed of movement on a moped depends on its power. Most modern chainsaws are equipped with motors, the power of which ranges from 2 to 3 liters. from. Such an internal combustion engine will be sufficient for driving at speeds from 35 to 45 km / h on a flat road;
  • fuel tank. it is best to choose a tank made of stainless steel. If a moped or carting from a chainsaw will be operated on a flat road, then a plastic tank is also suitable for assembling it;
  • switch and wiring for connection to the ICE ignition system;
  • the throttle handle and the connecting bicycle cable, which will allow the driver to timely adjust the position of the engine throttle valve;
  • parts for assembling the bracket, as well as nuts and bolts, with which the motor can be securely installed on the bike frame;
  • chains, pulleys and belts. necessary to connect the drive wheel to the engine from the chainsaw.

Much when assembling a moped depends on the correct sequence of actions by the manufacturer.

The work algorithm should be as follows:

  • First of all, the manufacturer must determine how the power is transmitted from the motor to the drive wheel. To do this, you will need to calculate the gear ratio of the unit in advance. If the gear ratio is too low, the engine from the chainsaw will not be able to provide the traction required for movement. As a result, a moped or ATV with your own hands from a chainsaw will not be able to start moving. If the gear ratio is too high, then the motor will start to operate at the maximum allowable speed, which will increase its wear. In this case, the bike itself will go very slowly. When calculating the gear ratio, the average example must be taken into account. So, if an engine is used to assemble a motorbike with a capacity of approximately 1.78 liters. sec., and rotation speed at maximum speed of 12500 rpm, then the gear ratio should be 1:26. The easiest way to transfer power from the pulley to the drive wheel is directly. A more costly method is to use a pulley or sprocket, which is additionally installed on the rear drive wheel. In this case, the wheel itself is connected to the motor using a chain or drive belt. When choosing between a belt and a chain, it is better to give preference to the first option, since using a belt when operating a homemade moped will be safer for the driver and his passenger;
  • In a second step, the manufacturer must assemble the clutch. At the same time, those who want to make a motorbike have 2 options. The first is the use of a ready-made centrifugal clutch, which was originally provided for in the branded device of the chainsaw and turns on automatically when the engine sets a certain speed of rotation. The second method is to use a bicycle ratchet. A moped equipped with such a clutch from a chainsaw picks up a certain speed of movement and rolls by inertia. At this time, the ratchet itself is not connected to the drive wheel. Thus, after several clicks on the throttle lever, the motorbike can move at idle speed for a rather long time. This allows the driver to save fuel, especially when driving on straight sections of the road;
  • The third step in making a moped from a chainsaw is installing the fuel tank and connecting the unit controls. The gas tank itself can be fixed next to the place where the used internal combustion engine will be mounted. The second option is to install the tank on the frame, but in this case, to connect it to the motor, you will need to run a fuel hose. To install the ignition, the operator will need to pull a wire from the motor and connect it to a switch located in advance on the handle. This will allow you to quickly shut off the engine if necessary. You will need to install the throttle trigger next to the ignition switch. You must first remove the retainer from it. This will allow the trigger to slide smoothly on the grip. Further, the cable from the gas trigger will need to be connected to the throttle valve of the standard carburetor.

Having assembled a moped from an engine from a garden tool, its owner can start testing a homemade product. To do this, fill the fuel tank with fresh fuel, prepared in the same proportion as for refueling the chainsaw, and start the engine with the starter. The first tank of fuel must be spent on running the moped, moving, at the same time, at low and medium speeds. After that, you can refuel the homemade product and start its more intensive operation.

How to put a chainsaw engine on a bicycle?

When assembling a motorbike with his own hands, the manufacturer will certainly be faced with the choice of how to mount the engine from a chainsaw. There are 2 methods for installing the motor. The first one is removable. This means that the owner of the homemade product will be able to remove the engine at any time and install it back on the chainsaw. The second way is to install the motor by welding it to the standard bike support frame.

Each of the methods of attaching the engine from a saw to a moped has its own advantages and disadvantages. The removable method is more practical, since it allows you to use the engine from a chainsaw for two purposes at once. Its only drawback is insufficient reliability, especially if a powerful motor is installed on the motorcycle, the strong vibration of which will gradually weaken the fixation of bolted connections.

Installing the motor on a moped by welding is more reliable. This method will allow the moped driver to move around uneven areas. However, the welded-on motor cannot be removed and reinstalled on the garden tool, which will significantly limit its applications.

It is best to mount the engine itself from the saw next to the rear wheel of the moped, since it is this wheel that plays the role of the leading one. This will allow the use of a short belt to connect the ICE with the wheel, which will not get tangled in the wheel spokes when the moped is driving off-road. To install the engine, it is best to first prepare a metal platform, which will play the role of a support-holder. Before installing the motor, you need to weld the holder itself in advance and check the reliability of its fixation on the frame.

After attaching the support to the moped frame, the motor itself can be installed on it. To prevent exhaust gases from getting on the driver and passenger while driving the moped, the engine must be turned so that the muffler is directed backwards. Further, if the operator does not remove the engine from the motorcycle, then the lower part of the internal combustion engine will need to be welded to the support. If the motor is removable, then you need to attach it to the holder using pre-prepared bolted connections.

To check the reliability of the motor fixation, the driver will need to drive the moped off-road. During the trip, you need to pay attention to the extraneous sounds that the internal combustion engine can make. If the driver noticed a knocking noise, then it will be necessary to check the engine mount and, if necessary, tighten the bolts.

Are there ready-made solutions?

Yes, everything can be much easier if you purchase a ready-made set of parts to make a bicycle with a chainsaw engine. In ready-made kits, in addition to the engine itself, there are all the necessary fasteners, as well as a throttle cable, a handle for power control, a forced engine shutdown button and other useful parts.

Bicycle with a motor: we connect the engine from a chainsaw with our own hands

If you have a thirst for experimentation and do not give up the opportunity to turn your bike into a homemade moped that can accelerate to 50 km per hour or more, this guide is for you.

Using simple parts, you can design a bike with a chainsaw motor with your own hands. Let’s get started!

  • Inspect and check your bike thoroughly. The proposed modernization will significantly increase the load on all its parts. Therefore, every detail must be inspected and well lubricated. Also check all fasteners and re-tighten the bolts. In addition to the constructive necessity, all these actions are the key to your safety.
  • You can make a bike with a chainsaw engine or a trimmer (also called a petrol cutter). If you are thinking about how to adapt a motor from a petrol cutter to a bicycle, then there is nothing difficult here. A petrol cutter is suitable for this design in the same way as a chainsaw. If you choose a chainsaw, make sure that its power is at least 2 kW. And if you have a trimmer, then 1 kW of power will be enough, since the engine of the petrol cutters is lower in speed. The point is that you have to get enough traction to get off the ground. But a more powerful engine means more weight. You need the weight of the motor not to exceed 6 kg, otherwise the bike will noticeably chatter on the road.
  • Check the engine for proper operation. A bike powered by a chainsaw will, of course, roar loudly. we suppose you are ready for it. Most likely, your neighbors and bystanders will not be ready. Therefore, we recommend that you conduct your tests away from human habitation. in a forest, in a park, on a country road.

Pay special attention to checking the condition of the gas tank. Gasoline must not spill out, as this creates a fire hazard. The engine will be behind you, so you should especially check this moment.

  • Now let’s figure out how to put a chainsaw engine on a bicycle. It is necessary to make room behind the cyclist, above the rear wheel. To do this, you have to remove the wing. The easiest way is to apply this scheme: put a drive shaft, and use a tire instead of a driven shaft. This type of drive is the simplest and most effective, the design does not require the use of a large number of parts. The friction shaft will transmit rotation from the engine, for this the shaft diameter should be approximately 25 mm.

Engine over the rear wheel of the bike

  • To mount the engine on your bike, weld a metal stand to the frame under the seat. Install the motor as low as possible, then your vehicle in motion will be more stable. You can fix the motor on the stand in any way. with bolts, clamps or by welding.
  • The gas cable and wires that will allow the engine to be forcibly shut off must be carefully secured to the frame. It is a matter of comfortable riding and cyclist safety.
  • Done! You can try your new bike with a chainsaw motor. Keep track of the tire pressure, it must be at least 3 atm.

Mobez using a chainsaw

Such a small moped can be made from a chainsaw. Actually, why not?

On chainsaws, of course, they do not install engines of the same power as on mopeds, but a simple apparatus will not hurt to assemble it.

So, in order to assemble a moped from a chainsaw, we need:

the actual engine from the chainsaw, frame,

As for the frame, any design you like will do. This can be a small moped frame, a bicycle frame, etc.

Choose the place to install the motor yourself. This may be a common place, like on a moped, but for this you will definitely have to strengthen the frame with additional labor. For this you need a welding machine. But, I think the best place would be to install the engine on the trunk. In this case, you only have to slightly strengthen the rear fork.

Chainsaw moped Then you need to install the clutch. You can use it ready-made (suitable from any moped) or make it yourself. To do this, you can take a car starter and cut the pads out of it. In general, the thicker and heavier the pads are, the better. Then we install the carburetor. It can also be taken from any moped. I think there will be an abundance of these parts at any dump. All parts should be thoroughly cleaned, washed with gasoline and installed in places convenient for you.

When everything is set, it’s time to get busy with the fuel tank.

It can be any plastic container with a volume of about 2 liters. Well, of course, a fuel tank similar to the one installed on a small-sized moped BMV-518 will look more aesthetically pleasing. Well I’ll probably have to go to the junkyard again.

Chainsaw moped. How to put a chainsaw motor on a bicycle

From a chainsaw motor and small wheels, you can build a workable moped that fits in the trunk (at that time. BMV518).

CHAINSAW MOPED Always interested in homemade chainsaw products. A couple of years ago I wanted to check whether it is true that a working moped that fits in the trunk (at that time. BMV518) can be built from a chainsaw motor and small wheels. I found an excellent motor with a gearbox from a friendship saw, wheels from a Vyatka scooter, a piece of 20×20 pipe and part of a moped frame. It worked out in a couple of evenings. In order for the engine to start and work, I replaced the carburetor with a moped one from d6. The result exceeded all expectations. a simple and reliable toy that entertained my friends all summer. Last spring, I realized that just repairing a moped was no longer interesting and, wishing to lighten the design, I made some changes. It turned out to be even more fun. And now I have exchanged this already fed up moped for the finished Malaguti grizzly 12. I want to shove the motor more powerful, let’s see I’ll try the motor from the partner chainsaw. Or, in extreme cases, from the STIHL 180 chainsaw.

The Pegasus moped attracts attention, first of all, for its fairly low price, and in truth, the quality of this model practically corresponds to its price. However, Pegasus managed to find its fans, mainly due to its ease of use.

Pegasus is produced at the “Leningrad Severny Zavod”. This factory specializes in the production of scooters. The model is equipped with a two-stroke 49 cm3 AnkurCM-50 engine from Indian manufacturers with a capacity of 2.4 horsepower. Power is certainly not ah. they are barely enough to reach speeds of up to 45 km / h. And under the guise, it becomes completely impossible. The moped engine runs on a mixture of A-92 gasoline with SAE-30O oil. Fuel consumption is about 1.5 liters per 100 km. A feature of the model is the absence of pedals, thanks to the kickstarter, the moped starts up without much effort.

The suspension is decent enough for such a small machine. The hydraulics are of decent quality, also of Indian origin, and even on difficult roads does not create much discomfort for the driver.

The levers and switches are also Indian, quite neat in appearance, but their location is rather unusual.

The Pegasus seat may not be very aesthetically pleasing, but it is quite comfortable and soft. The moped has drum brakes, spoked wheels.

The disadvantages of a moped include the presence of only one rear-view mirror, which turns out to be a difficult task to adjust, as well as the absence of a central stand.

In general, the Pegasus moped, a device that fully justifies its low price.

Prepare for the fact that you will have to spend a lot of effort and engineering savvy to achieve the intended goal. First, check the reliability of the bike, while keeping in mind that when installing a motor on it, you will need an additional load on all its parts. All moving parts must be lubricated. After selecting the motor, before dismantling, it is necessary to check the engine for noise level and its performance. In addition, it is necessary to select the engine by power, for example, a bicycle with a 1hp motor will not be able to move on its own, for this you will have to pedal or go down the mountain. It will be better to use more powerful engines, but they will be heavier.

the topic is interesting, mobility and compactness of movement.

I bought it 3 years ago for 18 thousand rubles. in Samara, the question was very relevant because of the endless traffic jams in a city with a multimillion population. The scooter weighed 19 kg, folded and fit in the trunk of a car. in general it is very convenient, took it out, started it and drove off.

As a result, it turned out: the steel of the structure is terrible, the assembly also sucks, from the vibration of the engine, the welding fell off in turn in all the nodes. rusty from moisture, paint fell off. I just broke off terribly, periodically bring the lifeless body of a scooter in my hands for repairs, to the garage, fortunately there was a minimum set of tools, a grinder, keys, etc. For welding, I had to go to look for auto workshops. The sellers knocked their heels on the chest, claiming that they themselves produce and collect, for reference, a sticker on a scooter and documents of NPO SATURN Samara. The only thing to which there are no questions is the engine, gearbox and disc brakes (native china prom). after the mother-in-law bought a bezo-trimmer, and I found on it an engine identical to the one on the scooter.

I found an excellent motor with a gearbox from a friendship saw, wheels from a Vyatka scooter, a piece of 20×20 pipe and part of a moped frame. It worked out in a couple of evenings. In order for the engine to start and work, I replaced the carburetor with a moped one from d6. The result exceeded all expectations. a simple and reliable toy entertained my friends all summer.

Last spring, I realized that just repairing a moped was no longer interesting and, wishing to lighten the design, I made some changes. It turned out to be even more fun. And now I have exchanged this already fed up moped for the finished Malaguti grizzly 12. I want to shove the motor more powerful, let’s see I’ll try the motor from the partner chainsaw. Or, in extreme cases, from the STIHL 180 chainsaw.

Pegasus moped and its features

The Pegasus moped attracts attention, first of all, for its fairly low price, and in truth, the quality of this model practically corresponds to its price. However, Pegasus managed to find its fans, mainly due to its ease of use.

Pegasus is produced at the Leningrad Northern Plant. This factory specializes in the production of scooters. The model is equipped with a two-stroke 49 cm3 AnkurCM-50 engine from Indian manufacturers with a capacity of 2.4 horsepower. Power is certainly not ah. they are barely enough to reach speeds of up to 45 km / h. And under the guise, it becomes completely impossible. The moped engine runs on a mixture of A-92 gasoline with SAE-30O oil. Fuel consumption is about 1.5 liters per 100 km. A feature of the model is the absence of pedals, thanks to the kickstarter, the moped starts up without much effort.

The suspension is decent enough for such a small machine. The hydraulics are of decent quality, also of Indian origin, and even on difficult roads does not create much discomfort for the driver.

The levers and switches are also Indian, quite neat in appearance, but their location is rather unusual.

The Pegasus seat may not be very aesthetically pleasing, but it is quite comfortable and soft. The moped has drum brakes, spoked wheels.

The disadvantages of a moped include the presence of only one rear-view mirror, which turns out to be a difficult task to adjust, as well as the absence of a central stand.

In general, the Pegasus moped, a device that fully justifies its low price.
