Abstract A known ski scooter, for use as sport and training equipment, has a foot board, on which the user's foot is secured by a binding, and sets of wheels adjacent the ends of the boards, one set being braked by a brake element linked to a brake lever formed for engagement of a ski stick in it. The invention has the brake lever as a hinged element operable by pulling it with a ski stick fitted with an engaging device, for example a rubber end member for the ski stick or a basket or a bearing ring with diametrically opposed extensions on it.
