In one embodiment there is a toy skateboard (100) having two configurations. In the first configuration, a pair of non-motorized truck assemblies (110,120) are attached to the deck (102), and the upper surface (103) of the deck has a finger engaging region for a user's fingers to engage and move the skateboard. In the second configuration, the rear non-motorized truck assembly is replaced with a motorized rear truck assembly (200), wherein the movement of the skateboard is controlled by the processor in response to remote signals. In addition, the processor may detect a back EMF voltage generated by the rotation of a motor caused by a manual manipulation of a wheel controlled by the motor. The processor would have sleep and wake states and would transition between the two when the detected back EMF voltage reaches a pre-determined value. |
