ABSTRACT:
A bicycle has a rear wheel assembly which is chain driven by the usual foot cranked sprocket. A front wheel assembly is also chain driven by a drive sprocket supported by the front suspension and steering system. The front drive sprocket is cranked by a reciprocating connecting rod. The handlebars turn the front wheel about a vertical axis to steer the bicycle, while concurrently it can also be pivotally moved forwardly and rearwardly. One end of the connecting rod is journaled to the pivotal handlebars such that pivotal motion thereof imparts reciprocal motion into the connecting rod to crank the drive sprocket which chain drives the front wheel. A biasing means is connected to engage the connecting rod at its extreme limits of travel whereupon the rod and drive sprocket are biased from its dead center position each 180.degree. of rotation of the drive sprocket and is forced over-the-center so that the apparatus can be used in conjunction with a free-running clutch such as found on a ten-speed bicycle, for example.
