The present invention disclose a continuously variable reciprocating prime mover. The feature of this continuously variable reciprocating prime mover is that the reciprocating rotatory motion of the legs is modified into the reciprocating linear flexion and extension of the legs, by which one leg is flexed while the other leg is stretching, the combined force of the legs can be multiplied by the force. After each linear motion stroke is completed, the reverse linear motion stroke is repeated, and the driving direction remains unchanged. At any moment of the full stroke of the reciprocating linear flexion and extension of the legs, both can generate 2 times of the instantaneous power equivalent to the maximum moment point of the circular rotation.

A lever driven bicycle with synchronous drive ratio control is disclosed. The lever driven bicycle may include a pair of drive levers pivotable around an axis. The lever driven bicycle may also include a force applicator connected to each drive lever, each force applicator configured to receive an application of a force to rotate a drive wheel. The lever driven bicycle may further include a control mechanism connected to the pair of drive levers, the control mechanism configured to synchronously adjust a drive ratio of each drive lever.
