  • Patent number: 6036210
    Abstract: A handcycle supports a rider in a forward leaning ("modified prone") position, with the feet of the rider in straps above the rear axle, and the arms hanging generally downwardly toward a pedal assembly. The pedal assembly is generally at about the chest portion of the rider, which increases the leverage that can be applied to rotate the hand pedals, thereby increasing the speed of the bicycle. The central bar of the cycle frame extends upwardly and forwardly to support a rider at an angle of between about 15 and 45 degrees, and more preferably at an angle of about 30 degrees from the rear axle. Appropriate padding and supports can be provided along the mid-portion of the bar to support the chest of the rider at the proper angle. A damper assembly connected between the front fork and the frame of the cycle provides variation in dampening for front wheel stability in changing road conditions. The gear shift and brakes are also easily accessible.
