Transmission structure for bicycle
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.
