A personal winter vehicle has a frame which includes a front portion and a rear portion. Preferably, the front and rear portions of the frame can flex with respect to each other. An operator-controlled motivator for generating torque, such as a pedal crank, is mounted on the frame. A drive assembly is attached to the rear portion of the frame and is mechanically coupled to and receives torque from the motivator. The drive assembly preferably includes a drive wheel rotatably attached to the rear portion of the frame and coupled to the motivator via mechanical coupling, and a track disposed around part of the circumference of the drive wheel. The drive assembly also may include a guide wheel rotatably attached to the frame and disposed in front of the drive wheel. The track is also disposed around the guide wheel. The front of the vehicle may include a ski which is turnable by operation of handlebars. Alternatively, there may be provided a front wheel also having a track. Brakes are provided, preferably caliper brakes which retard the rotation of the drive wheel and, if provided, the front wheel.

[ What is claimed is:] [1.]1. A personal winter vehicle, comprising:a frame, having a front portion and a rear portion;an operator-controlled motivator for generating torque mounted on said frame; anda drive assembly, attached to said rear portion of said frame, said drive assembly mechanically coupled to and receiving torque from said motivator, said drive assembly comprising:a drive wheel rotatably attached to said rear portion of said frame and coupled to said motivator via mechanical coupling, said drive wheel having a first circumferential rim;a single guide wheel rotatably attached to said frame and having a second circumferential rim, said guide wheel being disposed higher than said drive wheel so that a lowermost point on said guide wheel is above a lowermost point on said drive wheel; anda track disposed around at least part of said first and second circumferential rims, said track engaging said drive wheel, said guide wheel, and the ground, substantially all of said track being angled upwards owing to relative positions of said guide wheel and said drive wheel,wherein application of torque by said motivator is transmitted to said drive wheel via said mechanical coupling which rotates said drive wheel and moves said track and thereby propels said vehicle.
