In a multiple speed hub with coaster brake for a bicycle, unintentional jamming of the brake is prevented by the provision of novel pawl clutches interposed between a planetary transmission and the hub shell. The recesses of pawl carriers pivotally receiving the clutch pawls are circumferentially oversized to permit limited circumferential movement of each pawl between a driving position and an idling position.
