The front end of the frame is provided with a front fork with a handlebar, the middle of the frame is provided with a vertical bar with a saddle, and the rear end of the frame is provided with a bracket for installing a power drive mechanism; the front wheel is installed on the lower end of the front fork through the front axle; The wheels are installed on the rear end of the frame through the rear axle; the brake blocks are installed on the front and rear wheels; The left and right pedals at both ends of the central axis, the chain and the manual passive sprocket with overrunning clutch installed on the rear axle; the power drive mechanism is composed of an engine, a reducer and a chain drive installed on the rear end bracket of the frame. The engine The output shaft is connected with the input shaft of the reducer through a coupling, and the chain drive is composed of a power driving sprocket installed on the output shaft of the reducer, a chain, and a power passive sprocket with an overrunning clutch installed on the rear axle. When wanting to exercise the muscles and bones of the body and choose the human-powered driving mode to ride, step on the left and right pedals with both feet to make the central axis and the driving sprocket on it rotate accordingly, and pass through the chain and the human-powered passive sprocket with overrunning clutch. Drive the rear axle and the rear wheel on it to rotate, and the bicycle runs forward. At this time, the power passive sprocket with overrunning clutch is separated from the rear axle; The torque is transmitted to the rear axle through the coupling, reducer, power driving sprocket, chain and power passive sprocket with overrunning clutch, which drives the rear axle and the rear wheel on it to rotate, and the bicycle runs forward. The manpower passive sprocket wheel of clutch disengages from rear axle; Thereby reach the purpose of the utility model.
