A parallel vehicle includes three main control systems. The first controls the position and angle of the two parallel wheels relative to a fixed chassis, enabling the wheels to be moved outwardly and inwardly and the camber varied for greater stability, aerodynamic effect, or turning. This first system may be mechanically or hydraulically actuated, but preferably is controlled by a pair of control members whose position relative to the chassis corresponds to the desired position of the wheels relative to the chassis in order to provide an intuitive control mechanism. The second system is the propulsion system which may, for example, take the form of a derailleur drive of the type used in bicycles, but with power from the propulsion system being transmitted to the wheels via a rotating cable and individual gearboxes for each wheel which permit the direction of the wheels to be reversed. Finally, a braking system includes a braking mechanism which can be individually controlled to separately brake the wheels for steering purposes or to brake both of the wheels at the same time.
