[0002] A bicycle, also known as a bike or a bicycle, is usually a small two-wheeled land vehicle. After riding on the bicycle, people use pedals as power. It is a green and environmentally friendly means of transportation. More and more people use bicycles as fitness equipment for cycling exercises and bicycle travel. Cycling itself is also a sports competitive sport, including road cycling races, mountain bike races, track cycling races, stunt bike races, etc.
