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 first end, a second end, an upper surface, and a lower surface; a pair of non-motorized truck assemblies configured for attachment to the lower surface of the deck, each of the non-motorized truck assemblies having a pair of freely rotatable wheels, and wherein the pairs of wheels separately connect to at least one axle extending transversely to a longitudinal axis of the deck when attached; a motorized truck assembly configured for attachment to the lower surface of the deck, the motorized 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 motor-controlled wheel, of a pair of motor-controlled wheels, and wherein said receiver is configured to receive signals to control the movement of the pair of motor-controlled wheels; a first configuration, defined by having the pair of non-motorized truck assemblies separately attached to the lower surface proximate to the first and second ends, 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 one of the non-motorized truck assemblies and attaching the motorized truck assembly to the lower surface in replacement thereof, such that the motor-controlled wheels are proximate to one of the first or second ends while one of the pair of the non-motorized wheels remain attached proximate to the other end, and wherein movement of the toy skateboard is controllable by the processor in response to said signals, and wherein the pair of motors, includes a first motor coupled to a first motor-controlled wheel, of the pair of motor-controlled wheels, and the processor is configured to detect a back electromotive force (“EMF”) voltage generated by the rotation of the first motor caused by a manual manipulation of the first motor-controlled wheel both in a direction equal to a rotational direction of the motor-controlled wheel and in a direction opposite to the rotational direction of the motor-controlled wheel, and the processor is further configured to include at least a sleep state and a wake state and is configured to transition between said sleep state and said wake state when the detected back EMF voltage reaches a pre-determined value. |
