Abstract
Approximately vertical side walls are equally curved inwardly to form a waistlike narrow portion in the elongated body. A substantially flat bottom contact surface curves convexly downward to form a fulcrum at the low point. The fulcrum aligns with the centerlines of both side curves. A major portion of each side curve intersects a major portion of the bottom fulcrum curve to form a curved turning edge, which contacts the snow for its entire length when the snow board is tilted back over the fulcrum and to one side for steering. Protruding above a top flat ride-on surface are a rear foot stop and a double front foot stop for wedging the foot therebetween. Pivotally secured to an axle through the front foot stop a U-shaped handle pivots up for a stand-up balance and steering hand lever and down below the ride-on surface for storage, for a sit-down hand grip or for no-handle stand-up riding. Additional side grips, handle hold-down and safety release binding are optional.
