1. A motorized snowboard comprising: a board, having a top surface, a bottom surface, a width, a front portion, a rear portion, a midpoint, edges and an open channel in the rear portion between the opposing edges, the open channel having a forward portion at the midpoint of the board and a width less than that of the board;a track housing attached to the midpoint of the board, having opposing sides, overlying the forward portion of the open channel;binding mounts attached to the board forward and aft of the track housing;a track assembly, comprising: a continuous track,a top roller assembly having a leading roller and a trailing roller, each attached between the opposing sides of the track housing,a bottom roller assembly having a floating frame with opposing sides and a leading roller and a trailing roller each attached between opposing sides of the floating frame, wherein the floating frame is pivotally attached to the track housing, anda biasing mechanism to urge the floating frame downwardly; anda motor operatively connected to the track assembly for powering the continuous track. 2. The motorized snowboard of claim 1, wherein the pivotal attachment of the floating frame to the track housing is by means of two or more link members with first and second ends, each being pivotally connected to the track housing at their first end and pivotally connected to the floating frame at their second end. 3. The motorized snowboard of claim 2, wherein the leading roller and trailing roller of the bottom roller assembly are rearwardly offset from the leading roller and trailing roller of the top roller assembly. 4. The motorized snowboard of claim 3, wherein the continuous track comprises a roller chain and track plates. 5. The motorized snowboard of claim 4, further comprising drive paddles attached to the track plates. 6. The motorized snowboard of claim 5, wherein the motor has a drive shaft and the operative connection between the motor and the track assembly comprises a drive chain operatively engaged with one or more of the rollers of the track assembly to impart rotational motion thereto for propelling the motorized snowboard. 7. The motorized snowboard of claim 6, wherein the drive chain is operatively engaged with the leading roller of the top roller assembly to impart rotational motion thereto for propelling the motorized snowboard. 8. The motorized snowboard of claim 7, wherein the leading roller of the top roller assembly comprises a roller or a sprocket. 9. The motorized snowboard of claim 8, wherein the floating frame pivots between a first and second position and all intermediary points therebetween. 10. The motorized snowboard of claim 9, wherein the lowest portion of the track assembly protrudes just below the bottom surface of the board while the floating frame is in the first position and the lowest portion of the track assembly is at the farthest point from the bottom surface of the board permitted by the link members while the floating frame is in the second position. 11. The motorized snowboard of claim 10, wherein the biasing mechanism comprises a suspension member. 12. The motorized snowboard of claim 11, wherein the suspension member controls the movement of the floating frame between the first position and the second position. 13. The motorized snowboard of claim 12, wherein the suspension member varies in length between an extended length and a compressed length and is biased to the extended length. 14. The motorized snowboard of claim 13, wherein the bias to the extended length functions to maintain operative contact between the track assembly and an underlying ground surface when the board is in use. 15. The motorized snowboard of claim 14, wherein the one or more suspension members are comprised of shock absorbers and compression coil springs pivotally mounted to the floating frame at one end and the track housing at the other end. 16. The motorized snowboard of claim 15, wherein the open channel extends rearwardly from about the midpoint of the board. 17. The motorized snowboard of claim 16, further comprising a tensioning device on the frame to selectively adjust the distance between the rollers to thereby adjust the tension on the continuous track. 18. A motorized snowboard comprising: a board, having a top surface, a bottom surface, a width, a front portion, a rear portion, a midpoint, edges and an open channel in the rear portion between the opposing edges, the open channel having a forward portion at the midpoint of the board and a width less than that of the board;a track housing attached to the midpoint of the board, having opposing sides, overlying the forward portion of the open channel;binding mounts attached to the board on either side of the track housing;a track assembly, comprising: a continuous track,a floating frame having opposing sides, pivotally attached to the track housing,two or more rollers, one of which is a leading roller and one of which is a trailing roller, in forward and aft spaced apart relationship, wherein said trailing roller is attached between opposing sides of the floating frame, anda biasing mechanism to urge the floating frame downwardly with reference to the board; anda motor operatively connected to the track assembly for powering the continuous track.
