1. Field of the Invention
The present invention generally relates to tracked snow vehicles, and more particularly to two-wheeled tracked snow vehicles and conversion kits for creating them.
2. Background Information
The presence of snow in the wintertime severely restricts operators of two-wheeled vehicles from using their vehicles in the winter. Although other options are available, such as snowmobiles, there are no satisfactory two-wheeled vehicles for use in the winter. There are several versions of two-wheeled vehicles that attempt to provide a device that is similar in operation to a bicycle or a motorcycle, but configured for winter use. These can be gravity-powered devices on which a user straddles a frame and slides down a ski slope, and uses a steering wheel with an attached ski to navigate the hill. There are other devices that are similar to a motorcycle in configuration.
What is lacking in the prior art is a conversion kit for converting a two-wheeled vehicle, either a motorcycle or bicycle, into a tracked vehicle that can operate in the snow. Such a kit would also have the capability of being easily converted back into a two-wheeled vehicle. Such a conversion kit should include components that do not require serious modifications of the two-wheeled vehicle, such as by welding or cutting. Such conversion kits should be able to be bolted on with minimal complication.
Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
