The present invention is a fully functioning two-wheel drive bicycle and embodiments thereof. The drive train which supplies power to the front wheel is incorporated into a modified frame and comprises a rear wheel driven by the traditional chain or shaft mechanism and the front wheel driven by a series of rigid shafts or other internalized drive systems. The front wheel drive is adaptable to all bicycle frame geometries including the double diamond mountain bike and road bicycle frame, touring, commuter and comfort bicycles, BMX, trials bicycles, and recumbent and tandem bicycles. The drive train lengthens and shortens in parallel with the shock-absorbing front fork and rear suspension. An engagement clutch, a one-way hub, and torque limiting clutch are also disclosed.

The present invention is a two-wheel drive motorcycle. The drive trait that supplies power to the front wheel is modified to include a series of rigid shafts or other internalized drive systems. The front wheel drive consists of components located on the axis of steering within the head tube and positioned symmetrically in a counterbalancing fashion within the front fork in order to counteract the torque reactions from the rotating front wheel drive while providing a full range of steering. The front wheel drive lengthens and shortens in parallel with the shock-absorbing front fork. An engagement clutch, a one-way hub, and torque limiting clutch for the front wheel drive are also disclosed.

The present invention is a “three bar” rear wheel suspension system with increased lateral stiffness and reduced tendency for pedal induced bobbing. The rear wheel suspension system of the present invention features a rigid one-piece rear frame section and a short link that are attached with the front frame section at three pivot points. Movement of rear frame section along an arc defined by the length of the short link rather than along the arc that defines by the distance between the bottom yoke pivot point and the top yoke pivot point causes the rear frame section to flex. Active flexing of the rear frame section as it moves through its suspension range absorbs additional energy from the movement of the rear wheel resulting in an “active arc” second suspension system.
