The transmission is for transmitting a reciprocating pedal movement into a rotational movement and comprises a pair of pedals suspended for reciprocating movement, two rotating cam members (29) rotating around respective cam axes (33), each rotating cam member (29) having a peripheral cam surface (31), the rotating cam members (29) being coupled to a rotating member (35) through a respective one-way clutch. Flexible tension members (63) are connecting either peda to a respective one of the rotating cam members (29), which are eccentric to provide for a gearing ratio between angular movement of the rotating cam member (29) and translational movement of the respective pedal to vary,such that the gearing ratio has a minimum value when the pedal is in an intermediate position between its extended position and its retracted position, and major values when the pedal is in its retractedor extende dposition. |
