8. The wheeled sport apparatus of claim 7 wherein each of the first and second side edges of said platform defines a concave curve having a radius of about a turning radius.
9. The wheeled sport apparatus of claim 7 wherein the axes of rotation of the carrier wheels are above the bottom surface of said platform and below the top riding surface of said platform.
10. The wheeled sport apparatus of claim 7 wherein the axes of rotation of the carrier wheels are above the top riding surface of said platform.
11. The wheeled sport apparatus of claim 7 further comprising:
a mounting arrangement for receiving a foot restraining device on the top riding surface of said platform.
12. Wheeled sport apparatus comprising:
a platform having first and second ends and first and second side edges, having a top riding surface and a bottom surface, and having a longitudinal axis along its length substantially centrally between the first and second side edges;
a first set of wheels for rolling in a direction generally parallel to the longitudinal axis and located proximate the first end of said platform in spaced apart relationship generally along a line that is substantially perpendicular to the longitudinal axis of said platform, wherein at least two of said first set of wheels are disposed in openings in said platform;
a second set of wheels for rolling in a direction generally parallel to the longitudinal axis and located proximate the second end of said platform in spaced apart relationship generally along a line that is substantially perpendicular to the longitudinal axis of said platform, wherein at least two of said second set of wheels are disposed in openings in said platform; and
first and second carrier wheels disposed in respective openings in said platform between said first and second sets of wheels, the first carrier wheel being closer to the first set of wheels than to the second set of wheels, the second carrier wheel being closer to the second set of wheels than to the first set of wheels, and a diameter of the first and second carrier wheels being substantially the same as a diameter of each wheel of the first and second sets of wheels.
13. The wheeled sport apparatus of claim 12 wherein a turning radius: is about eight meters.
14. The wheeled sport apparatus of claim 12 wherein the axis of rotation of at least one wheel of the first set of wheels is between the top riding surface and the bottom surface of said platform.
15. The wheeled sport apparatus of claim 12 wherein the axis of rotation of at least one wheel of the first set of wheels is above the top riding surface of said platform.
16. The wheeled sport apparatus of claim 12 further comprising:
a mounting arrangement for receiving a foot restraining device on the top riding surface of said platform.
17. The wheeled sport apparatus of claim 13 wherein each of the first and second side edges of said platform defines a concave curve having a radius of about the turning radius.
18. Wheeled sport apparatus comprising:
a platform having first and second ends and first and second side edges, having a top riding surface and a bottom surface, and having a longitudinal axis along its length substantially centrally between the first and second side edges;
