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.

A bicycle drive unit comprises a frame main unit, first and second cover members, a rear hub, a rear gear shift apparatus, an electric driving mechanism and a power supply unit. The frame main unit diverges from a front end portion toward first and second rear end portions with the front end portion movably coupled to a frame of a bicycle, and the first and second rear end portions coupled to the rear hub. The first and second cover members are coupled to transverse outer surfaces of the frame main unit such that a first space is formed between the first cover member and the frame main unit and a second space is formed between the second cover member and the frame main unit. The electric driving mechanism is disposed in the first space and linked to the rear gear shift apparatus.

An apparatus for mounting a brake control element to a bicycle hub brake comprises a rotating member structured to be rotatably mounted relative to a fastening bracket so that rotation of the rotating member actuates a brake mechanism, wherein the rotating member includes a brake control element mount. The rotating member also has a cable winding surface to wind a brake actuating cable thereon. A brake control element attachment unit is structured to be attached to the brake control element mount, wherein the brake control element mount includes a locking structure such that rotation of the brake control element mount relative to the brake control element attachment unit locks the brake control element attachment unit to the brake control element mount.

An apparatus is provided for actuating a bicycle hub brake of the type having a fastening bracket adapted to be nonrotatably mounted relative to a bicycle frame, a brake drum, and a brake mechanism adapted to apply a braking force to the brake drum, wherein the brake drum rotates integrally with a bicycle hub around a hub axle. The apparatus comprises an actuating member and a rotating member. The actuating member is structured to be movably mounted relative to the fastening bracket for actuating the brake mechanism, and the rotating member is structured to be rotatably mounted relative to the fastening bracket independently of the actuating member. The rotating member includes an actuating member moving unit for moving the actuating member. The rotating member also includes a cable winding surface to wind a brake actuating cable thereon.
