Abstract

A remote control electric powered skateboard has a brushless motor or a brushless hub motor installed on the lower surface of the skateboard for connecting to a battery device through a controller, so that the motors could be electrified. A driving device disposed between either afore motors and at least one wheel is controlled by the remote control, thereby permitting an automatic comparison. When the electrification of the remote control executes, the remote control spontaneously generates an initial code for a receiver in the controller to robotically distinguish and lock the code. Turning off the remote control provides an automatic decoding. A receiver receives control signals from the remote control for the controller to interpret, and accordingly the controller generates and sends distinct commands to either motor, which allows the skateboard to implement various actions correspondingly. An auxiliary remote device disposed on the joint between a front support and a plywood is foldable or could stand on the skateboard; the height of the auxiliary remote device is adjustable for meeting divergent demands from dissimilar riders. A remote handle further provides the same operating means as that of the remote control for offering a supplementary supporting function.
