A skateboard has a plurality of in-line wheels rotatably mounted on the front end of the board and rear wheels disposed on either side of the rear end of the board. The left and right rear wheels are mounted incurvate with respect to the board and the in-line wheels to provide incurvated rear wheel steering for the board. The board may have a resiliently flexible portion between the in-line and rear wheels. The in-line wheels may be supported between a pair of parallel lateral flanges or they may be supported on a single flange that splits each in-line wheel. The rear wheels may be mounted on a coil and leaf spring suspension, on a transverse shaft or in housings at the rear end of the board. The rear wheels may be tapered.

[ What is claimed is:] [1.] A skateboard comprising:a board having a front end, a rear end, a top side, a bottom side, a left side, a right side and a median longitudinal axis running from the front end to the rear end dividing the left and right sides;a plurality of in-line wheels rotatably mounted on fixed axes on the bottom side towards the front end of the board, the in-line wheels being longitudinally disposed along the median longitudinal axis of the board;a first incurvating rear wheel rotatably mounted behind the in-line wheels on the left side towards the rear end of the board;a second incurvating rear wheel rotatably mounted behind the in-line wheels on the right side towards the rear end of the board; andwherein the first and second incurvating rear wheels are operably coupled to the board to incurvate with respect to the board and the in-line wheels to co-operate with the in-line wheels to steer the board to the left or to the right respectively when the skateboard rolls over a surface, the skateboard being steerable to the left by tilting the left side of the board downwards to steeringly engage the first incurvating rear wheel with the surface, and steerable to the right by tilting the right side of the board downwards to steeringly engage the second incurvating rear wheel with the surface.
