A hub is provided for a human-powered vehicle. The hub basically includes a hub axle, a member, a cable and a sealing element. The member is provided to the hub axle. The cable extends through a passageway. The sealing element is configured to occupy a space between the passageway and the cable.

A bicycle light that is constructed and arranged to be supplied with input electrical power. The power can be supplied by multiple power sources, or not. When there are multiple power sources, the bicycle light includes a circuit that is adapted to deliver power to the light source from any of the power sources. The bicycle light can have an electrical power output, and a circuit that is adapted to deliver power to the light source and the power output.

A hub is provided for a human-powered vehicle. The hub comprises a hub axle, a hub body, a sprocket support structure, a detected part and a rotation detection sensor. The hub axle has a center axis. The hub body is rotatably disposed around the center axis. The sprocket support structure is rotatably disposed around the center axis to transmit a driving force to the hub body while rotating in a driving rotational direction around the center axis. The detected part is provided to the sprocket support structure. The rotation detection sensor is configured to detect the detected part to detect rotation of the sprocket support structure around the center axis and being disposed in the hub body.

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.

The disclosure relates to the field of cycle technologies, and particularly to a wheel and a cycle. The wheel comprises a rim, a tire covering an outer periphery face of the rim, and a friction power device sandwiched between the rim and the tire; wherein the friction power device can produce a frictional current when pressed by the rim and/or the tire.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus comprises a driven mass configured to rotate in response to a kinetic energy of the vehicle, the driven mass coupled to a shaft, where rotation of the driven mass causes the shaft to rotate. The apparatus further comprises a hardware controller. The hardware controller identifies output power parameters for the vehicle and generate a control signal based on the identified output power parameters for the vehicle. The apparatus also comprises a generator that generates an electrical output based on a mechanical input and a conditioning circuit electrically coupled to the generator. The conditioning circuit receives the electrical output from the generator and the control signal from the hardware controller, generates a charge output based on the electrical output and the control signal, and conveys the charge output to the vehicle.
