Abstract:
In a first form, a drive sprocket is driven constantly in a forward direction. It is mounted on a central main shaft. A pair of mutually opposed one-way clutches each have a driving part on the shaft and a driven part on the sprocket, and in pedaling in either of opposite directions, the corresponding clutch becomes active and drives the sprocket in corresponding direction which is the same forward direction. In a second form, there is a direct drive unit, and a reverse drive unit, respectively driving the sprocket in its same forward direction.
