A bicycle gear hub (100) includes an axle (110), planetary gear modules (120, 130), one-way clutches (140, 150) and a shift mechanism (170). The planetary gear modules (120, 130) are connected in series at the axle (110). The shift mechanism (170) includes a shift actuator (172) and control pawls (174, 176) movably disposed at different positions of the axle (110). The shift actuator (172) includes recess portions (112, 114) to control opening and closing of a control protrusion (174C, 176C) of one control pawl (174, 176), and further to control a sun gear (126, 136) of the corresponding planetary gear module (120, 130) to the axle (110). When a high gear is shifted to a low gear, a rotational direction of the shift actuator (172) is identical to a rotational direction for closing the control pawl (174, 176).
