The Solowheel is pretty straightforward. It's basically just a 20 pound wheel that is powered by a 1,000-watt Lithium-ion battery — good for up to two hours on a single charge. Using its hidden gyroscopes, riders can accelerate by leaning forward and slow down by leaning backwards.
Newbies to transports with gyroscope technology will be able to learn how to ride the Solowheel in about 15 minutes says Shane Chen, President of Inventist.
Worried about safety? Chen says that the Solowheel is very safe. How safe? "There are no crashes because the rider will just hop right off," says Chen. Oh and it's street-legal, so you can ride the Solowheel pretty much anywhere.
Just like a Segway, the Solowheel isn't cheap. A single-wheeled transport costs about $1,500. You'll have to decide whether this electric unicycle is worth the money or just stick with your manual leg-powered bike.
