It may not be the same board that Marty McFly promised us we’d have by 2015, but it’s close enough for those of us who tried it at CES to be content. The OneWheel Self-Balancing Electric Skateboard uses a central go-kart wheel wrapped around a brushless electric hub to propel you forward (and backward) up to 20mph by simply leaning in the direction you want to go. Accelerometers, gyroscopes and advanced algorithms keep you upright, and the sensation of riding the board has been described as one “flying over the pavement”. Even though it has a somewhat limited range of 4-6 miles, the fast charger will fill the battery back up in as little as 20 minutes. Currently well funded on Kickstarter, a $1,299 pledge will get you a board with a standard charger (2 hour charge time), while an extra $100 covers the fast charger.
