A bicycle hub unit configured to be stably coupled to a frame of a bicycle includes a hub axle and a rotation restriction member. The hub axle is configured to be coupled to the frame of the bicycle. The rotation restriction member is configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted. At least one of the hub axle and the rotation restriction member has a cable guide structure configured to guide a cable, which electrically connects an electric component and an electronic component, in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle.

A bicycle hub assembly comprises a sprocket support body. The sprocket support body includes at least ten external spline teeth, a base support, and a larger-diameter part. The at least ten external spline teeth are configured to engage with a bicycle rear sprocket assembly. The at least ten external spline teeth radially outwardly extend from the base support. The larger-diameter part extends radially outwardly from the base support. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

Example bicycle sprocket assemblies are described herein. An example sprocket assembly includes a cassette formed by a plurality of sprockets arranged in increasing diameter order from a first end to a second end of the cassette opposite the first end. The cassette has a passageway extending between a first opening in the first end and a second opening in the second end to receive a driver hub. An outboard portion of the passageway is formed between a midpoint of the cassette and the first end of the cassette. The cassette further includes a torque transmitting profile located within the outboard portion of the passageway to interface with the driver hub. The sprocket assembly also includes a bushing to be disposed within the second opening to form a non-torque transmitting interface between the second end of the cassette and the driver hub.

A wheel hub assembly for a bicycle is disclosed. The wheel hub assembly may comprise a hub shell for a wheel and coupled to a hub body with an axle by a ratchet mechanism and configured to provide an engaged state where the hub body/axle and the hub shell/wheel rotate together and a disengaged state where the hub body/axle may rotate independently relative to hub shell/wheel; the ratchet mechanism may comprise a set of ratchet rings configured with a set of teeth and sets/groups of pawls configured to engage/disengage the teeth of a ratchet ring; ratchet rings may be configured/installed in the hub body in an aligned condition or an offset condition; when ratchet rings are configured in an offset condition the ratchet mechanism may be configured to facilitate a generally more responsive transition between the disengaged state and the engaged state for the hub body/axle and hub shell/wheel. The wheel hub assembly may comprise a hub shell/wheel and a free hub body/axle coupled by a ratchet mechanism comprising at least one ratchet ring with gear teeth configured to engage a corresponding set/group of pawls so that the wheel and hub body/axle may engage in a power-transmission state such as for forward driven movement; the ratchet mechanism with ratchet rings/pawls may disengage in a free-wheel state. The ratchet mechanism may comprise a ratchet ring arrangement with multiple sets of ratchet rings; with each ratchet ring in offset the number of effective gear teeth per cycle of rotation of the ratchet ring arrangement is greater than the number of gear teeth on each separate ratchet ring; the number of effective gear teeth able to be engaged (e.g. by pawls having a shape/profile to engage from one direction and disengage from one direction with gear teeth during rotation) provides variation of performance characteristics for the wheel hub assembly. A configuration with fewer effective gear teeth may allow for larger gears and greater durability/strength; a configuration with multiple pawls/pawl sets may allow for wider load distribution within the ratchet mechanism; a configuration with multiple offset ratchet rings may allow for improved responsiveness (e.g. within fewer degrees of rotation); a configuration with multiple aligned ratchet rings may allow for greater durability/strength and wider load distribution within the ratchet mechanism. The ratchet mechanism of the wheel hub assembly may be configured for a wide variety of applications, including road biking, mountain biking, electronic bikes. The wheel hub assembly is provided in a compact form/design to allow configuration in a variety of arrangements which can accommodated a variety of different ratc

A bicycle hub structure includes: a hub body including a first clutch ring, a sprocket support body connecting to the hub body and including a second clutch ring, first magnets and a magnetic ring. The magnetic ring is disposed on an axial side of the second clutch ring far away from the hub body, and the first magnets are disposed on a side of the second clutch ring adjacent to the magnetic ring. The sprocket support body includes a first state and a second state. In the first state, the first magnets and the magnetic ring attract the first clutch ring, so that the first clutch ring is in contact with the second clutch ring, and in the second state, a magnetic attracting force of the first magnets and the magnetic ring on the first clutch ring is less than that in the first state.
