Personal winter vehicle

A personal winter vehicle comprising:

• a frame, having a front portion and a rear portion;
• a motivator for generating torque motivated on said frame;
• a 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 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;
• and
• a 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;
• and
• a shock absorber connected between said front portion and said rear portion of said frame, said shock absorber being flexible and allowing relative movement between said front portion and said rear portion of said frame, wherein when stress is placed on said vehicle, said shock absorber flexes causing said guide wheel of said drive assembly to move downward closer to the ground, thereby placing more of said track in contact with the ground at a given time.

A snow cycle, comprising:

• a frame, having a front portion and a rear portion;
• an operator-controlled motivator for generating torque mounted on said frame;
• and
• a 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 circumferential rim;
• a single track guide attached to said rear portion of said frame and disposed in front of said drive wheel, said ouide wheel being disposed higher than said drive wheel;
• a track disposed around at least part of said circumferential rim, 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.
