Modern motor bicycle

The idea to put on a bike engine appeared for a long time: it was implemented in a moped. However, the moped is still a separate mode of transport, which is different from the bike greater complexity, weight and cost. At a time when cycling is popular as ever, and modern technology has reached a high level, cyclists and engineers went back to the old idea: to create an engine to a bicycle. On demand instantly responded to the proposal. And now the market is filled with a variety of bike engines: removable and fixed, petrol, gas and electricity. Briefly review each of them.

The gasoline engine for a bicycle

The market is now offering a wide variety of such engines. Typically, this single-cylinder two-stroke engines with air cooling and power from one to four horsepower. The main difference between them is the way to install on your bike. Here are some examples of the most popular units.

1. The motor bicycle, mounted on the frame, having a working volume of 50 cubic centimeters and a drive chainring. Its capacity is about one and a half horsepower, and a possible maximum speed not exceeding 30 km / h. The advantages of this solution are low price, low fuel consumption (1 liter per 100 km), the ability to use the bicycle speed switch and work the pedals. The disadvantages become great noise and low power when driving uphill.

2. Engine (bicycle) "Comet". This ready-to-install kit for placement over the wheel to which the drive will be made. Usually it is put on the rear trunk, and accordingly, the rear wheel is still leading, but the variant and install the front. Such engines are ranging from one to two horsepower and can overclock the bike up to 50 km / h. Absolute advantage "Comet" is compact and able to quickly remove. But he was twice the price of the frame and the engine not "presentable" looks.

3. Yamaha Motor. This is the best gasoline engine to a bicycle. The power units of the Japanese manufacturer can reach four horsepower, more than enough for a bicycle. Also best compared with the samples described above are the technical characteristics and exterior design engines Yamaha.

4. Engines of Chinese manufacturers. In China mass produced various aggregates that are not radically different from the above. China's only "know-how" is used as fuel gas.

Is the motor on the bike to put?

The electric motor has a number of significant advantages. He does not emit noise, has a great "pick-up", it does not require gasoline, and therefore harmless to the environment. The only, but a great disadvantage of any motor is the low battery capacity and the need to charge the clock. However, for a trip of 50 km they will suffice. For more distant biking, use a battery with a large capacity, and a dynamo driven pedal or one of the bicycle wheels. Of course, the electric motor for a bicycle - it is our future, but it will be present only when the batteries are invented with a sufficiently large capacity, or the ability to quickly charge.
