Ski attachment

A ski attachment attachable to a wheel, the wheel defining a nadir section, the ski attachment comprising:

• an elongated ski defining a longitudinal axis, the ski having a deck and a base, the ski defining longitudinally opposed nose and tail ends;
• a wheel mount for mounting the wheel to the ski at a location intermediate the nose and tail ends, the wheel mount defining a nadir receiving portion for receiving the nadir section, wherein the nadir receiving portion is closer to the tail end than to the nose end;
• and
• a wheel lock for locking the wheel to the wheel mount;
• wherein the base is configured so that a larger friction is exerted on the ski attachment rearward of the nadir receiving portion than frontward of the nadir receiving portion when the ski attachment is pushed on snow at an angle relative to the longitudinal axis;
• wherein the wheel mount includes a tail wheel holder and a nose wheel holder each movable longitudinally along the deck;
• wherein the ski attachment defines a tail rail and a nose rail each extending longitudinally along the deck, the tail and nose wheel holders being mounted respectively to the tail and nose rails so as to be longitudinally movable therealong;
• and
• wherein the ski attachment defines a longitudinally extending toothed surface longitudinally serrated, and wherein at least one of the tail and nose wheel holders defines a wing defining wing teeth, the wing being resiliently deformable between an undeflected configuration and a deflected configuration, wherein the wing teeth are configured and sized to engage the toothed surface to longitudinally lock the at least one of the tail and nose wheel holders relative to the deck.
