Not quite a Back To The Future hoverboard, but certainly the Gnarboard Electric Skateboards are the next best thing. They're available in three different models - The Commuter, The Road Warrior and the oh-so-cool Trail Rider which does 0-28mph in an incredible 1.9 seconds. The other two Gnarboard Electric Skateboards aren't particularly slow either, though a helmet is highly recommended. They are all powered by rechargeable LiPo batteries.
