ABSTRACT:
A tandem bicycle drive train system includes a continuously variable transmission installed around each crank spindle driving an input crank spindle journalled in a continuously variable transmission unit whose output is connected to a drive sprocket which is journalled between the input crank spindle and the transmission unit. A manual ratio control assembly is suitably mounted to the frame member and positioned around the input crank spindle and suitably coupled with the transmission unit in a manner that provides a smooth, continuously variable change in the input to output rotational speed ratio. Each rider's ratio control is preferably coupled to a manual twist-grip on each rider's handle bar and can be adjusted independent of the other rider's control. The front unit output drives a single sprocket which drives one of two sprockets mounted on the rear unit. A second sprocket on the rear unit drives the rear wheel. Thus, the drive line is at all times a single drive line with two or more variable speed torque inputs from the transmissions around each input crank spindle. Each unit is suitably mounted within an oversize input pedal spindle housing in such manner as to permit sealing from outside contamination.
