Abstract
A two-wheeled combination roller skate-ski includes a base with safety straps and front brake, two wheels, a transverse frame and a longitudinal frame. A player may select to use either the transverse frame or longitudinal frame to mount the wheels outwardly of two opposing sides of the base in a position such that intersections of a plane in which the base lies and circles defined by the wheels are chords of the circles. Hubs of the wheels are located above the base of the skate-ski, imparting additional stability to the skate-ski and helping the player to maintain his balance.
