Wheeled vehicle i.e. bicycle, has motor coupling transferring torque of electric motor on rear wheel, where electric motor includes rotor with rotor cup formed in outer housing of electric motor

摘要

The vehicle i.e. bicycle has a pedal crank (10) for converting muscle power into torque, and a pedal crank coupling for transferring the torque to a rear wheel (B). A motor coupling transfers a torque of an electric motor (20) on the rear wheel. The motor includes a rotor with a rotor cup having a bottom and a peripheral wall, where operation of the motor causes a stator to electromagnetically interact with the rotor cup. The rotor cup is formed in an outer housing of the electric motor.
