SpnKiX designed by Peter Treadway of LA and creative agency Jpworks of Beijing, are battery powered skates that strap onto ordinary shoes.
They are hand controlled by a wireless remote. All hardware and electronics are integrated into a frame made of fiber reinforced nylon, with one motor and battery pack per foot.
A wireless remote controls both feet at once. The remote straps to your hand and you can vary the throttle with the continuously variable speed control. They come with removable training wheels so anyone can master them easily.
