Abstract
A bicycle hub includes a hub shaft, a hub shell, a bearing arrangement, an electricity generating mechanism and at least one lamp. The hub shaft is configured and arranged to be mounted in a non-rotatable manner to a bicycle frame. The hub shell has a hollow interior with the hub shaft being disposed in the hollow interior of the hub shell. The bearing arrangement is arranged between the hub shell and the hub shaft in such a manner that the hub shell can rotate freely with respect to the hub shaft. The electricity generating mechanism is arranged inside the hub shell and is configured to generate electricity in response to relative rotation of the hub shell with respect to the hub shaft. The lamp is arranged on at least one end of the hub shell and illuminated using electricity generated by the electricity generating mechanism.
