ABSTRACT:
A bicycle coaster brake hub having a gear-transmission therein is provided with a change-over mechanism between a driving member or clutch always rotatable together therewith and a gear frame including planetary gears and carrying actuators, such as rollers or a clutch, for operating brake shoes of a braking mechanism. The change-over mechanism causes a reverse rotation of the driving member induced by back-pedalling to be transmitted to a ring gear instead of the gear frame, whereby the gear frame is always reversely rotated through the ring gear at any driving speed stage from low to high thus braking the bicycle wheels with a uniform braking effect regardless of what speed stage the gear-transmission is in at the time of braking.
