In one embodiment there is a toy skateboard having two configurations. In the first configuration, a pair of non-motorized truck assemblies are attached to the deck, and the upper surface 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, 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. |

1. A toy skateboard assembly comprising:
a deck having a front region, rear region, an upper surface, and a lower surface; a front non-motorized truck assembly and a rear non-motorized truck assembly configured for attachment to the lower surface of the deck, the front and rear non-motorized truck assemblies having a pair of freely rotatable front wheels and rear wheels, respectively, and wherein the pairs of front and rear wheels extend transversely to a longitudinal axis of the deck when attached; a motorized rear truck assembly configured for attachment to the lower surface of the deck, the motorized rear truck assembly configured to house at least (i) a battery, (ii) a processor, (iii) a receiver in communication with the processor, and (iv) a pair of motors, each motor separately controlling a rear wheel, of a pair of rear wheels, and wherein the pair of rear wheels are positioned transversely to the longitudinal axis of the deck and behind the pair of front wheels, and said receiver configured to receive signals to control the movement of the pair of rear wheels; a first configuration, defined by having the front non-motorized truck assembly attached to the lower surface towards the front region and having the rear non-motorized truck assembly removably attached to the lower surface towards the rear region, and wherein the upper surface defines a finger engaging region for a user's fingers to engage and move the toy skateboard; and a second configuration, defined by removing the rear non-motorized truck assembly and removably attaching the motorized rear truck assembly to the lower surface towards the rear region, wherein the movement of the toy skateboard is controllable by the processor in response to said signals. |
