    Abstract: A ski riding apparatus comprises a horizontal platform mounted on three skis with one positioned rearwardly and two, in side by side positions forward. A steering column extends upwardly from the platform terminating with a steering brace. The rider stands on the platform leaning forward against the brace and in this position is able to lean from side to side to steer the apparatus. The forward end of the platform is rotationally engaged with a laterally extending ski support positioned forward of the platform. The ski support provides laterally spaced apart engagement elements with the dual front skis. By tilting the platform a sprocket is rotated within the ski support housing and by belt or chain drive, this sprocket rotates lateral ski sprockets for tilting the forward skis in coordination with the tilting platform.
