ABSTRACT:
Apparatus that simulates the exercise obtained in either of two modes of bicycling, e.g. sit-down, normal pedalling; and stand-up, hill climbing pedalling. Two different systems are disclosed, both yielding the desired bimodal choice of exercise. One system includes the use of clutches and gearing that allows switching between the normal 180.degree. fixed pedal relationship and a relationship that assists each pedal through bottom and top dead center, with the unweighted pedal being returned by the force generated by the other pedal as this other pedal is moved through the most powerful portion of the pedalling cycle. The second system includes the use of locking ratchets, adjustable spring returns, and adjustable stops to allow switching between the normal 180.degree. fixed pedal relationship and a relationship that avoids passage of the pedals through top and bottom dead center and confines all pedal movement to the power portion of the pedalling cycle. In both systems the "down" pedal is effectively braked or stopped to provide a step-up platform to provide for body lifting in the "stand-up" mode.
