A dual drive bicycle having a hand crank mechanism for applying driving power to the front wheel of the bicycle includes a stabilizer bar attached to a hand crank mechanism frame, the stabilizer bar including a chest saddle against which the rider positions the chest area of his upper body during operation of the front wheel hand crank mechanism. The force applied by the rider's upper body against the chest saddle acts to maintain forward alignment of the front wheel of the bicycle to thereby greatly improve the stability of the bicycle. In addition, the stabilizer bar and chest saddle combination provides a resistance against which the rider works while operating the front wheel hand crank mechanism.
