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.

[ I claim:] [1.] In a parallel vehicle comprising:a pair of wheel hubs;only two side-by-side wheels attached to the parallel vehicle, each rotatably mounted on a respective one of said wheel hubs such that said vehicle includes no wheels other than the two side-by-side wheels; andan assembly to which said only two side-by-side wheels are rotatably mounted, said assembly including:a chassis having two sides;means for connecting the hubs to the chassis such that said hubs are non-rotatable with respect to said chassis;a support structure positioned between the two sides of the chassis and below a center line connecting the wheels; andpropulsion means depending from said support structure for causing rotation of the wheels relative to said hubs to propel said vehicle, the improvement wherein:said means for connecting the hubs to the chassis include first and second wheel position control means for changing a relative distance between respective ones of said wheels and the chassis by changing a distance between at least one of said hubs and said chassis during said rotation of said wheels.
