What is the name of the small engine on the bicycle in the 1990s

Flywheel: The flywheel is screwed at the right end of the rear axle, maintaining the same plane as the sprocket, and through the chain and The sprockets are connected to form the driving system of the bicycle. Structurally, it can be divided into two categories: single-stage flywheel and multi-stage flywheel.

It seems that the gasoline engine installed on bicycles was not invented in the United States. There have been similar gasoline engines installed on bicycles in China for a long time. But most of them drive the chain and then drive the rear wheel.

The engine is installed in the bicycle and becomes a motor. I have it at home, but it's the kind of old bicycle modified in the 1980s. I haven't ridden it for many years, and it's aging there. It seems that those who are not allowed to ride horses out now will be detained. It's better to buy an electric car. It's convenient to install a white license plate without fuel money, which is environmentally friendly and economical.

I have a mountain bike that I want to modify. I don't know if it should be changed to an electric one? It's better to install an engine...

Just one word: cool. I don't know how many times faster the speed, and then it's still the feeling of riding a bicycle, which is really fast.

Yes, just install an electric motor assembly and a battery (this type of bicycle is also sold on the market). But in fact, no one should dress like this, because it's not worth it. In addition to the time and money, the main purpose of riding a mountain bike is to exercise.

It can be, but it's unrealistic.If a mountain bike needs to be converted into an electric car with a battery, first of all, how to install the battery is a big problem. Mountain bikes don't have shelves, and it's not very convenient to install shelves, and they don't look good. Installing it on the frame will affect the work of the front chain.

Can the kind of bicycle with shock absorption be equipped with an engine? A high finger tap..

On an ordinary bicycle, two engine tubes are installed in the rear bicycle tire position, and then the engine tube is equipped with an engine, and liquefied gas is connected as an energy supply to drive the jet engine. Such a bicycle equipped with a jet engine can reach a record of 70 kilometers per hour under the bold test of this foreign man.

The oil seal of the shock absorber is not good for the oil, and the oil will also corrode the oil seal. Adding oil will definitely leak oil. It's just a matter of time. Generally, shock absorber oil is sold in hardware stores or agricultural machinery stores, and you can just say that you need hydraulic oil. Generally, the riding distance of the 5 yuan 500ml mountain bike race is 40-50. Kilometer.

——There is motivation, but don't be a master. 4——There must be a lot. It's about 100 pieces old, 50CC, because it's very simple.

At present, there are two main types of engines for mopeds on the market, one is gy6 and two is lh100. They are very similar. In most cases, the hl100 engine cannot be equipped with double shock absorber or change the disc brake. Explosive modification is a very troublesome and unsafe thing.
