A bicycle drive mechanism which allows desynchronized pedaling. Pedals connected to shuttles are mounted in rail guides for generally linear movement. The pedals are elastically connected to each other which allows each pedal to move independently of each other for at least two inches of desynchronized motion. A drive element is mounted around two approximately equally size sprockets. Pushing each pedal either pushes or pulls the drive element around the sprocket. The rotation of the sprockets drives a standard bicycle gear sprocket and chain mechanism to power the rear wheel of a bicycle.
