Solowheel: self-balancing Single wheel EV Specs
Weighing 25 pounds (11 kg), sporting folding leg platforms on each side and a carry handle on top, the 17 x 19 x 5-inch (43 x 48 x 13 cm) Solowheel from Inventist is sure to turn some heads as you trundle along at up to 12mph. The durable external housing hides a Li-ion battery that's said to be good for two hours of use between charges and a 1000-Watt electric motor, and a self-balancing gyro system. Its battery is reported to take 45 minutes to charge but a regenerative system returns energy to the battery when the rider slows down or the unit goes downhill, which could help extend the range.
The electric unicycle's creators say that it's easy to use and quick to learn, the feet are quite close to the ground and the legs rest against each side of the housing which help with balance and steering. With both feet on the vehicle, you just lean forward to start going. When you want to slow down or stop, you lean back. You use the legs to steer, much as you would on the Magic Wheel.
Jinalyn Liljedahl from Inventist told Gizmag that he expects the Solowheel to be available from April at a cost of US$1495. Each unit will be shipped with an instructional DVD and charger.
I can see the Solowheel being a useful, fun and quite affordable way to trundle from the railway station into work and back again. Have a look at the following demonstration video and see what you think:
