Abstract
Abstract A ski vehicle with improved front support means is provided which includes a two-wheeled powered vehicle body frame, seat, motor, powered rear support wheel and steering means, including handle and front wheel frame. The front support means for the vehicle is in the form of a bracket secured to the wheel frame, a ski support assembly pivotably connected to the bracket to permit transverse rotation of the former relative to the latter, a pair of skis pivotably connected to the spaced depending legs of the assembly and means interconnecting the bracket and each ski, whereby rotation of the bracket and frame in a transverse plane effects like rotation of the skis. The skis can also rotate upwardly and downwardly, the extent being controlled by limit means. Means may also be provided to limit the extent of transverse rotation of the skis and to releasably lock the bracket and ski support assembly together for ease of transportation.
