Abstract
The bicycle of the invention provides a frame having forward and rear frame portions that are selectively attach and detach from each other in upright and recumbent positions. In the upright position, cranks are connected to a gear box that is adapted to drive a typical chain sprocket. In the recumbent position, the cranks are removed from the rear gear box and are attached to a forward gear box. A drive shaft is positioned between the gear boxes so that the bicycle rider may power the bicycle from the forward gear box. The bicycle may also be configured to be used as a tandem with a second set of cranks attached to the rear gear box.
