A multi-terrain riding board includes an elongate deck mounted on a chassis, a front axle assembly pivotally coupled with the chassis and including a pair of horizontal spindles rotatable about respective vertical axes, a pair of wheels mounted for rotation about the spindles, a pair of tie rods connected between the chassis and the spindles to transfer tilting movement of the chassis into rotation of the spindles about the vertical axes, a rear axle coupled with the chassis, and a rear wheel rotatably mounted on the rear axle. In one embodiment, the rear axle is fixedly connected to the chassis so that the rear wheel cambers in response to angulation of the deck; however, the rear axle can be pivotally coupled with the chassis and provide with a pair of spindles and tie rods to steer like the front axle assembly if desired. Preferably, horizontal tension springs are connected between the spindles and a bottom portion of the chassis to help stabilize the deck of the riding board. An engine or motor can be mounted within the chassis between the front and rear axle assemblies, in which case the deck is preferably hingedly connected with the chassis to permit pivotal movement of the deck from a lowered position resting on the chassis to an elevated position allowing access to the engine.
