摘要

The drive has a first winding device (3) fixed on a first driven axis (2), and a second winding device (9) on a second axis (8) spaced away from the first. The second winding device in a rotational direction is rigidly coupled to the second axis for a force transmission and which in the opposite rotational direction has a freewheel. A first connecting element (7) is provided between the first and second winding devices can be alternately wound on and wound off up to a stop, whereby the winding off from the second winding device takes place against the force of a return spring. An independent claim is included for a bicycle equipped with the aforesaid drive.
