Abstract
A control mechanism for decoupling a drive ratchet on a bicycle hub makes it possible to push the bicycle backwards while the foot pedals of the pedal crank drive remain still. These functions can be applied to folding bicycles, in which pedal movements are harmful when in their folded up state. The control mechanism includes a controlling sleeve coupled to the drive ratchet, which is indirectly connected by means of a frictional device to the unmoving hub axle.
