Abstract
A bicycle motor unit includes an electric motor and a transmitting structure. The electric motor is configured to generate a driving force. The transmitting structure is coupled to the electric motor to transmit the driving force from the electric motor to an actuated device of a bicycle. The transmitting structure includes a first rotatable member, a second rotatable member, and a resisting structure. The first rotatable member is rotatable about a rotational axis. The second rotatable member is rotatable relative to the first rotatable member about the rotational axis. The resisting structure is at least partially provided between the first rotatable member and the second rotatable member so as to resist relative rotation between the first rotatable member and the second rotatable member.
