The Snow Rider provides two separate platforms, each equipped with a pair of truck mounted skis, interconnected via a centerline articulated spar. Each platform undergoes an angle change before articulating with the trucks. This angle change is referred to herein as the truck angle, which determines the degree to which the skis turn relative to the long axis of the Snow Rider for a given amount of rotation of the platform about the centerline. The trucks translate leaning by the rider into a redirection of the skis, which through the use of ski riser mechanisms between the platforms and skis, are simultaneously rotated about their long axis to get the skis up on edge and in contact with the snow.

1. A snow rider system for enabling a rider to create turns by shifting their weight such that the supporting platforms cause the surfaces that are in contact with the snow to synchronously turn and rotate, comprising: first and second platforms, interconnected in a linear arrangement by an articulated spar, and having a platform center line axis extending along a length of the first platform, the articulated spar and the second platform, from a first end to a second end, for supporting a rider;first and a second pairs of skis, wherein each of the pairs of skis comprise first and second skis, each ski of each pair of skis being on opposite sides of and oriented substantially parallel to the platform center line axis;first and second trucks, connected to the first and second pairs of skis, respectively, for connecting the first and second pairs of skis to the first and second platforms; andwherein the first and second platforms are independently rotatable relative to one another about the platform center line axis, in response to the rider shifting their weight to either side of the platform center line axis as the surface rider moves either down an inclined surface or towed across a substantially flat surface, to provide a variety of combinations of relative orientations between the parallel pairs of skis, including both point in the same direction, one pointing in one direction, while the other points in the opposite direction, one pointing straight ahead, while the other points in either direction, and all combinations between. 2. The snow rider of claim 1 wherein the articulated spar comprises: first and second spars, each composed of a cylinder having first and second ends, with one cylinder at an angle to the other and sharing the same center line axis; anda center spar, connected to the second end of the first spar and the first end of the second spar to interconnect the first and second spars along the center line axis, while allowing them to rotate about the center line axis. 3. The surface rider of claim 2 wherein the center spar comprises: a flexible connection between the first and second spars, to create an increasing restorative torsion that is proportional to the relative angle between the first and second spars to bring the first and second platforms in a linear relationship along the platform center line axis. 4. The snow rider of claim 3 wherein: the first truck is rotatably connected to the first end of the first spar to enable the first truck to rotate about the center line axis as the rider shifts their weight on the first platform while providing a restorative torsion to the truck to maintain the first set of skis in contact with the snow; andthe second truck is rotatably connected to the second end of the second spar to enable the second truck to rotate about the center line axis as the rider shifts their weight on the second platform while providing a restorative torsion to the truck to maintain the second set of skis in contact with the snow. 5. The snow rider of claim 4 wherein the first and second spars are connected by the center spar which maintains the second end of the first spar at an angle with respect to the first end of the second spar such that the first spar and second spar are responsive to redirection of the first pair of skis, to redirect the second pair of skis in a direction that is opposite to the direction of the first pair of skis thereby to form a piecewise linear arc. 6. The snow rider of claim 1 wherein each of the first and second trucks have bearings that connect to the associated skis and each articulate with the associated ski to enable the ski to rotate about a line sement running the length of the bearing and constraining any other motion with respect to the truck. 7. The snow rider of claim 1 further comprising: first and second ski riser mechanisms connected to and interconnecting the first and second skis with the first and second platforms, respectively to translate leaning by the rider into a redirection of the skis. 8. The snow rider of claim 1 further comprising: ski to ski connectors that articulate with the proximal ends of each pair of skis that are essentially in line to allowing the distance between the two pairs of skis to vary while keeping them essentially in line. 9. The snow rider of claim 1 further comprising: first and second bindings, attached to the first and second platforms, respectively, for securing the first and second platforms to the feet of the rider such that the rider's feet are substantially parallel and perpendicular to the center line axis. 10. The snow rider of claim 1 further comprising: binding free platform connected to one of the platforms to provide support for one foot of the rider enabling the rider to control the torsion applied to the binding free platform when their boot is not secured to the binding free platform.
