Patent ID: 8056916

Claim:
A drive system for use with a cycle having at least one wheel, the drive system configured to combine arm power of forward and aft movement of a handlebar with leg power of a sprocket and chain system to drive the at least one wheel of the cycle while providing for regular foot pedaling and steering of the cycle, the drive system comprising: an arm power headset configured to allow the handlebar to turn in a desired direction of travel while being moved forward and aft and while at a same time twist on a vertical axis to steer the cycle without adversely affecting either steering or powering of the cycle, the arm power head set comprising: a universal joint assembly configured to provide forward and aft movement of and twisting movement inside the headset at the same time, thereby allowing for steering with the handlebar in a conventional manner; and a mounting bracket coupled to the universal joint assembly and a frame of the cycle; a push/pull rod configured to convert forward and aft arm movement into rotary movement, the push/pull rod coupling the arm power headset assembly to a first drive assembly; the first drive assembly comprising a first drive sprocket coupled to a first crank shaft; a second drive assembly on the same side of the cycle as the first drive assembly, the second drive assembly coaxially coupled and in driving relationship with a drive sprocket of the cycle; and a linking device linking the second drive assembly with the first drive assembly.
