What is a moped?

A moped comprises a frame, a front wheel, a rear wheel, a five-way valve installed at the bottom end of the frame and an engine, wherein the frame of the moped consists of hollow pipes which are communicated with each other, and fuel is filled in the hollow pipes.

The top of the front and rear ends of the frame are respectively provided with an oil filling hole and an exhaust hole, and an oil pipe is communicated between the lower part of the frame and the engine. The moped of the utility model is simple in structure, small in volume, light in weight, safe and reliable, and very beautiful.

Classification:

There are two main types of fuel mopeds, one is a two-stroke scooter similar in appearance to an electric motorcycle, and the other is a single-cylinder four-stroke fuel moped. The former is simple in principle and small in size, but it is noisy and consumes a lot of oil. When driving, it will emit a blue smoke due to insufficient combustion.

The second type adopts four strokes, which doubles the lever stroke of the engine every time it works (that is, four strokes), enhances the sufficiency of gasoline fuel combustion and greatly reduces pollution and noise. It must be pointed out that the mopeds that are driving now basically belong to the single-cylinder four-stroke type, in fact, the fuel economy is still good.
