Abstract

See full text

A bicycle gear hub includes an axle, planetary gear modules, one-way clutches and a shift mechanism. The planetary gear modules are connected in series at the axle. The shift mechanism includes a shift actuator and control pawls movably disposed at different positions of the axle. The shift actuator includes recess portions to control opening and closing of a control protrusion of one control pawl, and further to control a sun gear of the corresponding planetary gear module to the axle. When a high gear is shifted to a low gear, a rotational direction of the shift actuator is identical to a rotational direction for closing the control pawl.
