A dual driven cycle and a kit for converting conventional, single driven cycles into dual driven cycles are disclosed. The invention is suitable for accommodating bicycles, motorcyles, dirt bikes, and other conventional cycles. These cycles have the known elements of a pedal-gear-chain driven first wheel and a non-driven second wheel. The kit comprises four general elements. First, a sprocket is connectable in fixed relation to the non-driven second wheel for conjoint movement with that wheel. Second, to receive power from the conventional drive train, a drive gear is mounted on either the pedal gear or chain of the cycle. Third, a cable gear is provided for mounting with respect to the cycle's frame and meshing with the sprocket. This cable gear drives the sprocket and, of necessity, the cycle's previously non-driven second wheel. The final general element of the kit is a rotatable cable which connects the cable gear to the drive gear and transfers the rotational motion of the drive gear to the second wheel.
