Abstract:
A multi-wheel bicycle with a dual universal joint disposed on a bicycle frame, wherein a first end of the universal joint is mounted to the bicycle frame and a second end of the universal joint is mounted on a moveable end of a bicycle steering fork. A front drive chain is couple from the universal joint to a front tire disposed on a free-wheeling front hub, and a second drive chain is coupled from the first end to a drive sprocket. The drive sprocket is further coupled to a free-wheeling hub attached to a front tire. The coupling provides for transfer of rotational power from the drive sprocket to the front and rear tires through the dual universal joint even as the universal is flexed through its range of motion while steering the bicycle.
