You don’t always need a car to get around in your city. Take this Self Balancing Electric Unicycle. It is an elegant self-balancing unicycle that only requires you to stand on its two folding feet pads. It has gyroscopic sensors that detect your movements and help you keep your balance. Leaning forward accelerates your ride whereas leaning backward slows your unicycle down. The unicycle’s 500-watt electric motor moves a 160-lb. rider up to two hours at 13 mph with a three-hour charge of its built-in lithium-ion rechargeable battery. Not cheap though.
