The present invention relates to a bicycle driving apparatus with a novel structure which allows a bicycle to move forward by alternately pushing each of both pedals in one direction. Since a user repeatedly presses down a left pedal (113) and a right pedal (114) to move a bicycle forward, the bicycle driving apparatus according to the present invention has an advantage of more convenience of use than a conventional bicycle driving apparatus in which the left pedal (113) and the right pedal (114) should rotate.

A gear mechanism is provided, having a gear arrangement, and a spindle arrangement to support the gear arrangement, the spindle arrangement having first, second, third and fourth spindles. The gear arrangement, of concentric gears only, that includes a first gear set mounted on the first and fourth spindles and arranged to be driven via a first pedal, a second gear set mounted on the second and fourth spindles and arranged to be driven via a second pedal, and a third gear set mounted on the third and fourth spindles, wherein, for each of the first and second gear sets, the gear set is configured to be alternately driven, via the corresponding pedal being rotated through less than 180, in a power stroke to drive the third gear set, and, advanced, via the corresponding pedal being rotated through more than 180, in a return stroke to commence a subsequent power stroke.

A transmission structure for a bicycle includes two opposite transmission units. Each of the transmission units includes a linear reciprocating pedaling mechanism, a transmission module which is in transmission connection with the linear reciprocating pedaling mechanism, and a resetting module connected with the transmission module. The transmission modules of the two transmission units are connected with a power output mechanism through a unidirectional transmission mechanism. The transmission module includes a first driven wheel and a first transmission gear configured to be coaxial with the first driven wheel. The resetting module includes a connecting piece and an elastic piece. The connecting piece is connected with the first transmission gear. The elastic piece is connected with the connecting piece.

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.
