Used to see the wheelbarrow of the relevant information, no intention to pull out some of the Monowheel / Unicycle information, the original guy in 1869 was Richard C. Hemming applied for a patent, was "manual" design.

After some people have improved the new wheelbarrow - Monowheel, but has not been widely used, more just appear in a variety of performances.

As for the main reason is not widely used, in fact, because the control too slag. The drive and direction are responsible for the only one wheel, causing the turn to become unusually inefficient. People have tried to tilt the car, leaning on the weight; slow down and a pedal to the opposite direction; even the brake roll drift turn and so on but failed to solve this problem. In addition to this section of the wheelbarrow there are stability problems, the driver is difficult to keep the car at rest when the stability does not fall.

In addition to the next driver, Monowheel is harder to have enough space to load the goods or passengers; the brakes, the rush when the rider is easy to roll like a small hamster in the cage, Embarrassing); because this section of the wheelbarrow appearance is composed of a hollow tires and composition, although in recent years there is no shortage of upgraded version of the emergence of engraved goods, but after all, can not board the table. Moreover, regardless of the hub to change more than fine, it will always block the driver's sight.

Therefore, this section of the wheelbarrow is eliminated by history, the wheelbarrow must advance with the times can be long-term development, and in Unicycle China, you can choose to advancing with the times wheelbarrow!
