The hoverboard is built to handle smooth surfaces in which riding on the board on gravel roads will damage the hoverboard sensors. The all-new 6.5″ wheels hoverboard is a two-wheel electric device that is purely operated by your feet. The hoverboard has an internal gyrostabilizer to ensure an easy-to-learn riding experience. Use subtle body shifts, to move forward, backward, make turns and even rotate 360 degrees around your axis! With a sleek modern design the hoverboard is great for indoor and outdoor fun.
