Solowheel, designed and made by the 54-year-old Shane Chen, is a self-balancing electric unicycle, the smallest, most environmentally friendly, and most convenient way to build a manned vehicle. The exterior consists of a wheel and two foldable pedals, which operate on a gyroscope sensor, a motor and a lithium-ion battery. Solowheel is simple and easy to learn, flexible and safe. It can only be moved by the change of the center of gravity of the sensor, and the weight is only 20 pounds. It is the best choice for work, school and travel entertainment.

The method is as follows:

When the rider puts his foot on the folded pedal on either side of the wheel, the body tilts forward gently forward, which means to stop, the body tilts to the left and to the right. The more the body leans forward, the faster the Solowheel is, and a series of gyroscopic devices in the car make sure it is well balanced.

A spokesman for the washington-based company said: "Solowheel is the smallest, greenest and most convenient manned vehicle we have ever invented. Our new self-balancing electric unicycle is more compact than any folding electric bike and is more fun to use. Because it has a gyroscope sensor, it has the ability to control the left and right, so you just put your feet up and you can go. It's very simple to use. A Solowheel is very light, and you don't have to lock it up because it can be carried around and not easily stolen. Solowheel provides users with a simple, convenient and practical means of walking.

"Solowheel" is similar to the Segway -- a power-driven, self-balancing electric car. But it is smaller and more convenient than the Segway, which can be thrown directly into the trunk of a car, referring to a home or office. If you suspect that a two-wheeled electric car is too bulky, try Solowheel.

Finally, make sure to read the instructions carefully before use, understand how to use them, and wear a full set of safety suits. First use the familiar stage suggest the body only do a little tilt, accelerate slowly, don't be too fast, more practice, just like learning to ride a bike, I fell it doesn't matter, important is familiar with it to harness it, soon you will become the focus of square street.
