Patent attributes
A bicycle arm-drive apparatus includes a stationary mounting structure, an arm drive input mechanism, a drive motion transmission mechanism, and a plurality of connectors. One end of the mounting structure attaches to the front-center portion of the bicycle. The arm drive input mechanism includes a pair of control arms that pivotally attach to the other end of the mounting structure and generally extend rearward and outward from there. The operator grips each control arm, inputting arm power by driving them fore-and-aft. The drive motion transmission mechanism includes a pair of connecting rod assemblies running down opposite sides of the bicycle frame between the control arms and bicycle pedals. A plurality of connectors link the connecting rod assemblies to the pedals and control arms in order to transmit control arm fore-and-aft movement via the connecting rod assemblies to the pedals to enable the arm power to assist with bicycle pedaling.
