Abstract:
A hub transmission for a bicycle comprises a hub axle; a driver rotatably supported to the hub axle; a hub shell rotatably supported to the hub axle; a power transmitting mechanism disposed between the driver and the hub shell for communicating rotational power from the driver to the hub shell through a plurality of power transmission paths; a shift mechanism for selecting the plurality of power transmission paths; a shift assist mechanism for communicating rotational power from the driver to the shift mechanism; and a power control mechanism disposed between the driver and the shift assist mechanism and coupling rotational power from the driver to the shift assist mechanism for communicating non-constant rotational power from the driver to the shift assist mechanism.
