Abstract
A freewheeling overrunning clutch for a bicycle, moped, and the like vehicle comprises a plurality of clutch pawls present between an outer wheel and an inner wheel which are supportable elastically on one side on the inner wheel circumference and on the other side on a plurality of inner teeth of the outer wheel. In order to provide a simple, almost noise free structure which is easy to mount, the clutch pawls pivotally supported in a flexible supporting ring positioned between the inner and outer wheels. Ends of the clutch pawls which face the inner wheel are brought into engagement with the plurality of teeth protruding outward from the inner wheel. The flexible supporting ring advantageously may simultaneously be a spacing ring for a plurality of balls of a ball bearing or bearings positioned adjacent the clutch pawls between the outer and inner wheels.
