ABSTRACT:
A bicycle bottom bracket structure is provided that has a dynamo for generating electricity when the rider is pedaling the bicycle. The dynamo has a stationary part fixed to a portion of a bicycle frame and a rotational part coupled to rotate relative to the portion of the bicycle frame. Preferably, the rotational part of the dynamo is coupled to an axle of the bicycle bottom bracket structure via a planetary gear unit. Thus, the planetary gear unit is coupled between the axle and the rotational part of the dynamo such that the rotational part of the dynamo rotates faster than the axle.
