ABSTRACT:
A skateboard-type sports apparatus has a frame forming a grip for the user and provided internally with a standing surface beneath which a pair of roller elements can be provided. The roller elements are rotatable in respective holders which can be rectangular frame members pivotally mounted on the frame so that a pin and an eyelet on opposite sides of each member define a pivot line for the roller. The rollers can thus pivot in planes substantially perpendicular to a central plane of the frame.
