PURPOSE: A bicycle comprising a traction-type combined power generator and electric motor is provided to improve durability and maximize service life by effectively reducing vertical impacts acting on the electric motor. CONSTITUTION: A bicycle comprises combined power generator and electric motors(30,30'), a small gear, an auxiliary wheel(40), a large gear, a control box, a rechargeable battery, and a changeover switch. The combined power generator and electric motors, comprising a rotating plate(10) and fixed plates(20,20'), are arranged at an interval. The rotating plate gas a magnet and the fixed plates have a coil and a fastening hole(22). The small gear is coupled to one side of each combined power generator and electric motor and connected to a rotary shaft. The auxiliary wheel is installed on the underside of the combined power generator and electric motors. The large gear is installed via a shaft where a rear wheel is mounted and engaged with the small gear. The control box and the rechargeable battery are connected to the combined power generator and electric motors. The changeover switch is installed on a handle of the bicycle. |
