ABSTRACT:
A skateboard having independently pivotally mounted trucks affixed to the skateboard axle on the underside of the footboard. Each of the trucks has a pair of wheels that are rounded or tapered in the direction toward the surface on which the skateboard is used to approach a point contact with the surface. Due to the independent suspension of each truck, in the event one of the wheels of one truck encounters an obstacle, that wheel can raise upwardly to ride over the obstruction while all of the other wheels can remain in contact with the surface. As such there is a stable ride even when riding over obstacles and the contour or profile of the wheels tends to also promote a stable ride since the wheel profile tends to push small obstacles away rather than riding over the obstacle.
