ABSTRACT:
An internal gear shifting hub includes a motor that assists in gear shifting operations. The internal gear shifting hub is mounted at on rear portion of a bicycle frame and includes a hub shaft, a drive cylinder, a hub shell, a power transmitting mechanism, a shift mechanism and a generator mechanism. The drive cylinder and hub shell are both rotatably mounted to the hub shaft. The power transmitting mechanism is mounted between the drive cylinder and the hub shell and transmits rotational force from the drive cylinder to the hub shell via one of a plurality of force transmission paths. The shift mechanism shifts between the plurality of transmission paths. The generator mechanism is mounted alongside the power transmitting mechanism inside the hub shell and generates electric power via the rotation of the hub shell to power the motor.
