US Patent 7226063 All-terrain board

An all-terrain board comprises an elongate deck structure 10 having an upper surface on which front and rear axle assemblies 13,14 are mounted, such that the deck structure 10 extends under the axis of wheel rotation. The rear end 12 of the deck structure 10 is upturned and extends rearwardly beyond the rear wheel 15, thereby providing a rear position for one of the rider's feet, which can be used as a kicktail to raise the front end 11 of the board to perform turns and other freestyle maneuvers. The kicktail also enables the front of the board to be raised to clear or mount obstacles.
