The invention is a conversion kit for converting a conventional two-wheeled vehicle, such as a bicycle or motorcycle, into a tracked vehicle for use on snow, mud and sand. The kit converts the vehicle without major modifications to the vehicle, and the vehicle may be converted back to two-wheeled use easily. The tracked version is powered by the original vehicle drive system, and uses the vehicles braking and suspension system.

I claim: 1. A snow vehicle conversion kit for converting a two-wheeled vehicle to a tracked snow vehicle, comprising: a ski and strut assembly which replaces the front wheel of the vehicle by attaching to the front fork assembly of the vehicle; a drive gear which replaces a rear wheel of the vehicle, said drive gear having track drive teeth around its circumference, an attached drive sprocket which interfaces with a drive chain of the vehicle, and a braking surface congruent with a brake system of the vehicle; and a track assembly mounted to the frame of the vehicle, comprising a track assembly frame rotatably mounted to the vehicle frame at a rear axle of the vehicle, a plurality of idler wheels, an endless loop track defining windows in said track, which is configured for interfitting with said track drive teeth of said drive gear for propulsion, a generally linear slider extending from adjacent a leading idler wheel of said track to adjacent a trailing idler wheel for holding said track to a curved shape and at least one control rod, with a first and a second end, connected to the vehicle frame at the first end and to the track assembly frame at the second end, for pulling the rear of the track assembly down, but limiting the distance the rear of the track assembly can move in a downward and an upward direction. 2. The snow vehicle conversion kit of claim 1 in which said track has metal clips on the interior of the track, with part of the metal clips extending into the track windows for reinforcing said track windows and forming ridges on the track interior normal to the track. 3. The snow vehicle conversion kit of claim 1 in which said frame members of said vehicle are rear wheel stays of a bicycle. 4. The snow vehicle conversion kit of claim 3 in which said brake surface is congruent with caliper brakes of said bicycle. 5. The snow vehicle conversion kit of claim 1 in which said frame members of said vehicle are swing arms of a motorcycle. 6. The snow vehicle conversion kit of claim 5 in which a plurality of idler wheel pairs are mounted to the track frame, and contact the interior of the track adjacent to the ridges. 7. The snow vehicle conversion kit of claim 1, which includes a slider attached to the track frame, and mounted to impart a curve to said track at a leading side of said track. 8. The snow vehicle conversion kit of claim 1, which includes a brake disk that interfaces with a disk brake of said vehicle. 9. A method of converting a two-wheeled vehicle into a track driven snow vehicle, said method comprising the steps of: attaching a ski and strut assembly to a conventional two-wheeled vehicle, in place of the front wheel of the vehicle, by attaching the ski and strut assembly to the front fork assembly of the vehicle; removing the rear wheel of said conventional two-wheeled vehicle, and installing in its place a drive gear, said drive gear having track drive teeth around its circumference, an attached drive sprocket which interfaces with a drive chain of the vehicle, and a braking surface congruent with the brake system of the vehicle; and installing a track assembly by attaching said track assembly to the frame of the vehicle, said track assembly comprising a track assembly frame rotatably mounted to the vehicle frame at the rear axle of the vehicle, a plurality of idler wheels, an endless loop track defining windows in said track, which is configured for interfitting with said track drive teeth of said drive gear for propulsion, and a slider adjacent part of said track installing at least one control rod, with a first and a second end, connected to the vehicle frame at the first end and to the track assembly frame at the second end, for pulling the rear of the track assembly down, but limiting the distance the rear of the track assembly can move in a downward and an upward direction. 10. The method of convening said two-wheeled vehicle into a track driven snow vehicle of claim 9, which includes the step of installing a continuous track in which said track has metal clips on the interior of the track, with part of the metal clips extending into the track windows for reinforcing said track windows and forming ridges on the track interior normal to the track. 11. The method of convening said two-wheeled vehicle into a track driven snow vehicle of claim 9, which further includes the step of installing said continuous loop track between the rear wheel stays of a bicycle. 12. The method of convening said two-wheeled vehicle into a track driven snow vehicle of claim 11, which further includes the step of installing a drive gear with a braking surface that is congruent with caliper brakes of said bicycle. 13. The method of converting said two-wheeled vehicle into a track driven snow vehicle of claim 9, which further includes the step of installing said continuous loop track between the rear swing arms of a motorcycle. 14. The method of converting said two-wheeled vehicle into a track driven snow vehicle of claim 9, which further includes the step of installing a plurality of idler wheel pairs mounted to the track frame, which contact the interior of the track adjacent to the ridges. 15. The method of converting said two-wheeled vehicle into a track driven snow vehicle of claim 9, which further includes the step of installing said slider so that said slider is attached to the track frame, and mounted to impart a curve to said track at a leading side of said track. 16. The method of converting said two-wheeled vehicle into a track driven snow vehicle of claim 9, which further includes the step of installing a brake disk with said drive gear, which interfaces with a disk brake of said vehicle.
