| Abstract: |
A manually powered front wheel drive cycle particularly adaptable for use by paraplegic individuals. A drive train has a first drive linkage operably connected to front wheel means for rotation of the front wheel upon actuation of the drive train. The first drive linkage extends upward to a power transmission assembly. A second drive linkage extends rearward from the power transmission assembly to a hand crank mechanism. A tiller bar is connected between the power transmission assembly and the hand crank mechanism. Operation of the hand crank mechanism by the rider effects movement of the cycle. Lateral movement of the hand crank mechanism rotates the tiller bar and front wheel means for steerage of the cycle.
