A combination driving hub and transmission for a cycle—such as a bicycle. The inventive hub is preferably installed on the rear of a bicycle. A pair of reciprocating cranks provide input torque to corresponding input shafts. These input shaft transmit the torque through a series of step-up shafts. The step-up shafts increase the speed of the initial input—finally delivering the torque to an output shaft. The output shaft is preferably the hub of the bicycle's rear wheel.
