Abstract
A drive mechanism is disclosed that is selectably engageable to provide a bicycle that has normally driven and nondriven wheels with either single or dual wheel drive. The drive mechanism includes a power take off means that has: a first power transmission mechanism mounted on said frame; a second power transmission mechanism mounted on the bicycle frame in positive drive power transmitting engagement with a normally non-driven wheel of the bicycle; and a power transfer apparatus connected to receive power from the first power transmission mechanism and transmit it to the second power transmission mechanism. A coupling mechanism is operatively connected with the power take off and is selectively actuatable to place the first power transmission mechanism either in a drive position receiving power from the normally driven wheel or a disengaged non-power transmitting position. An actuator mechanism is mounted on the bicycle to selectively move the coupling mechanism either to the disengaged position or to the drive position to energize the power transfer apparatus and drive the normally non-driven wheel.
