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 configured to resemble a reduced-scale skateboard having a first end, a second end, an unobstructed upper surface, and a lower surface; a pair of non-motorized truck assemblies configured to resemble reduced-scale skateboard truck assemblies, and further 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, wherein the pair of non-motorized truck assemblies are separately attached to the lower surface proximate to the first and second ends of the deck to define a first configuration such that the unobstructed upper surface defines a finger engaging region for a user's fingers to engage and move the freely rotatable wheels along a riding surface; and a self-contained motorized truck assembly having a pair of motor-controlled wheels and further having a housing configured to contain at least (i) a battery, (ii) a processor, (iii) a receiver in communication with the processor, (iv) a pair of motor-controlled axle gears separately extending from sides of the housing and secured to a motor-controlled wheel, of the pair of motor-controlled wheels, and (v) a pair of motors, each motor separately controlling a motor-controlled wheel, of the 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 and wherein the processor is configured to control the movement of the pair of motor-controlled wheels in response to said signals to include at least the turning of the toy skateboard, such that turning the toy skateboard does not require a leaning object or leaning figure positioned on the upper surface to turn the toy skateboard, and wherein the self-contained motorized truck assembly is further configured to completely replace one of the non-motorized truck assemblies such that when said non-motorized truck assembly and its pair of freely rotatable wheels are removed from the lower surface of the deck and the self-contained motorized truck assembly and its motor-controlled wheels are secured to the lower surface of the deck in place of said non-motorized truck assembly such replacement defines a second configuration, and wherein the second configuration is further defined to place the motor-controlled wheels on said riding surface such that movement of the toy skateboard through the motor-controlled wheels is further controlled by the processor. |
