A rear-wheel drive for a bicycle or a trailer bike comprises an output sprocket of a chain drive, a rear-wheel shaft, and a driving mechanism being supported outside to the bicycle frame. The rear-wheel shaft is supported only on one side of the driving in a supporting manner relative to the bicycle frame. The driving mechanism on the side facing the bicycle frame is not, as commonly known, supported relative to the rear wheel shaft but relative to the bicycle frame. That creates the required space for arranging a freewheel clutch, that fulfills the strength requirements for transmitting the occurring torques even when using sprockets with only a few teeth. Thus, short distances between the rear wheel and the bottom bracket and single-arm suspensions in the bicycle frame can be implemented together with the implementation of suitable developments of the chain drive for small running wheels.
