Looking like an accident waiting to happen, but actually being an ingenious piece of design, the Onewheel Self-Balancing Electric Skateboard ($TBA) perhaps makes the skateboard accessible to just about everyone. Basically, if you can stand you can skate on this device, thanks to its use of physics that let you just use your own balance to stay on board.
Hilariously, the guys at Future Motion said they were trying to replicate Marty McFly´s hoverboard from Back to the Future and this was the ultimate result. Either way, if you want to go forward you lean forward and if you want to go back… well, you get the picture.
Oh, and by the way, this thing is closer to that hoverboard than you might expect as it is motor driven (20 minutes on one charge) so you really will feel like you´re hovering.
