Electric bicycle

摘要

An electric bicycle (1) is provided which is capable of detecting precisely torque generated by man power and driving a motor (8) exactly depending on the torque to support driving force by man power. The electric bicycle (1) includes a man power driving part (10) rotating a wheel (3) by rotation of pedals (11), an electric driving part (9) rotating a wheel (3) by drive of a motor (8), a torque detection part (41) detecting torque generated by the man power driving part (10), a control part (26) controlling drive of the motor (8) and a disk casing (5) comprising the motor (8) and the torque detection part (41).
