An electric motor bicycle system with an electric motor driven gear adapted to drive a wheel gear coupled to a bicycle hub. The motor driven gear is coupled to the wheel gear with a chain. The chain may be tensioned with one or more tensioners, which allow for a tighter system geometry. The motor may be supported with a bracket adapted to mount to industry standard disc brake mounting interfaces. In some aspects, the motor driven gear is coupled to the disc mounting interface of a wheel hub. In some aspects, the electric motor bicycle system may also have a disc brake system integrated therein.

A bicycle battery system includes a battery assembly and a battery lock. The battery assembly includes a battery and a handle assembly mounted to the battery. The handle assembly includes a handle mount, a handle plunger, and a handle. The battery lock is mounted within a cavity of a frame of a bicycle and configured to secure the battery assembly within the cavity. The battery lock includes a lock plunger, a movable latch, and a stationary latch. The lock plunger is configured to press a portion of the handle mount against the movable latch when the battery lock is in a locked position such that the battery assembly is securely mounted within the cavity. Responsive to the battery lock being in an unlocked position, the handle plunger is configured to cause the handle mount and the handle to pivot away from a face of the battery such that at least the portion of the handle mount engages the stationary latch of the battery lock.

A power module of an electric assisted bicycle is disclosed and includes a pedal shaft, a gear-plate-output shaft, a reducer-output shaft and a motor-output shaft. The pedal shaft is arranged along an axial direction. The gear-plate-output shaft includes a first section and a second section arranged in the axial direction. The first section is concentrically sleeved on the pedal shaft through a first one-way bearing along a radial direction. When the pedal shaft is forced to rotate, the gear-plate-output shaft is driven through the first one-way bearing. The reducer-output shaft is concentrically sleeved on an outer surface of the second section through a second one-way bearing along the radial direction. The motor-output shaft is concentrically sleeved on the reducer-output shaft along the radial direction. When the motor-output shaft drives the reducer-output shaft to rotate, the gear-plate-output shaft is driven by the reducer-output shaft through the second one-way bearing.

A pedaling sensing device of an electric bicycle is configured to connect to a motor and includes a crank axle, a first gearwheel, a second gearwheel, an assisting unit and a sensing unit. The crank axle extends along an axial direction and has a plurality of first helical teeth connected to each other and arranged continuously. The first gearwheel is disposed around the crank axle and comprises a first inner annulus surface and a first outer annulus surface. The first inner annulus surface is formed with a plurality of second helical teeth matching the first helical teeth. The second helical teeth are connected to each other and arranged continuously. The second gearwheel is disposed around the first gearwheel and has a second inner annulus surface. The second inner annulus surface is formed with a second transmission structure matching the first transmission structure.

A hub assembly is provided for a human-powered vehicle. The hub assembly includes a hub axle, a hub body, a cable and a cable protector. The hub axle has a first axial end and a second axial end. The hub body is rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly. The cable has a first portion disposed inside of the hub assembly and a second portion disposed outside of the hub assembly. The cable protector is movably arranged between a first position and a second position. The second portion of the cable extends along the rotational center axis where the cable protector is in the first position. The second portion of the cable being at least partly restrained in an angled position with respect to the rotational center axis where the cable protector is in the second position.
