The solowwheel is the ultimate personal transportation device. Small, simple to operate, and you can carry it like a briefcase into classrooms, offices and restaurants or onto the subway, bus, train or airplane. It weighs 13KG, as little as a student's backpack or a professional's briefcase. (With the foot-platforms folded up it's actually smaller than most briefcases. ) It takes about a half hour to learn the basics of riding, about a day or two to become proficient. (how long did it take to learn to ride a bike? ) Just lean forward to go forward, lean back to stop. Lean left or right to turn. That's all there is to it. Once you get used to it, it's almost magical. Just think where you want to go, and you go there.
