It is a complex machine composed of many simple machines. During the Qing Dynasty, Kangxi made great efforts to develop bicycles. "The great history of the Qing Dynasty" records: "Huang Lei Zhuang made two wheeled cars, a long three feet, can sit on one person, do not need to push pull, can be self." When the line is on the side of the arm, it will follow the curve around the arm. It will follow the same line as follows. "Follow your feet and walk for eighty Li." It can be seen that the bicycle he made has a wheel around the front and back, and the rider can turn around the axis of the hand, and the car can move forward. This is the earliest bikes recorded in the history. About 100 years after Huang Zhuang Zhuang, French Siv Lark made wooden bikes in 1790.
