Abstract: A snow ski simulation apparatus which employs a plurality of in-line wheels mounted onto a longitudinally flexible ski chassis member having torsional rigidity which is generally greater than the longitudinal flexibility of the ski chassis. A simulated ski camber is created by providing in-line wheels positioned in spaced apart relationship along the longitudinal length of the ski chassis member. The differential diameter of the spaced-apart in-line wheels facilitates longitudinal flexion of the ski chassis member upon a user weighting or unweighting the ski apparatus in a manner which simulates snow skiing. In this manner the ability of the user to turn and modulate the arc of each turn by angulation relative to the running surface and weighting and unweighting of the ski apparatus is greatly enhanced.
