Abstract: The present invention encompasses several improvements to handcycles. This invention introduces a blend between lean steer and pivot steer. The front wheel may be turned with only minimal twisting of the operator's legs. This invention uses two bearings and quick release axle to connect the front and rear frame together and provide the steering axis. This invention incorporates a means for adjusting the bike from fully reclined to a body forward position. The invention also incorporates a means of crank adjustment. In the embodiment of our new design the cable and housing are attached to the brake and shift levers by means of an intermediate device for the purpose of directing the shift and brake cable away from the rider's field of view.

Abstract: A stabilizer includes a base and a shaft rotatively mounted to the base. An arm attached to the shaft is able to swing about the axis of rotation defined by the shaft in response to centrifugal force. In one possible application, the stabilizer can be incorporated into a vehicle. The vehicle includes a first frame and a second frame pivotally connected to the first frame, wherein the frames pivot with respect to one another about an axis of rotation. The second frame includes an outwardly extending support arm having a seat mounted thereon. The arm swings in response to centrifugal force so as to laterally displace the seat relative to the first frame. In one aspect, the seat is located below the axis of rotation.

Abstract: A cycle with a mechanical advantage drive and leaning steering system comprises a frame with at least one wheel rotationally attached to the frame. A drive rim is attached to the wheel adjacent to the outer circumference of the wheel. A pulley is rotationally attached to the frame. A belt is trained around and engages both the pulley and the drive rim. Because the belt is positioned at the outer circumference of the wheel a mechanical advantage is created that significantly reduces the amount of force required on the belt to propel the cycle. The cycle may be steered via the rotation of the rider's body on a seat. This rotation translates to rotation of a front portion of the frame with respect to the a rear portion of the frame about a pivoting interface portion, thereby causing the cycle to turn.
