A unicycle for thrill-seekers

Extreme sports enthusiast Hunter Howell has created a unicycle that you can not only ride, but also spin.

He used a tractor tire and a lawn mower engine as a basis, proving that innovation does not require expensive components - just ingenuity and a healthy dose of fearlessness. This hybrid of a carousel and a vehicle accelerates to 65 kilometers per hour.

Before a test ride on such a wheel, you should think about whether your vestibular system can handle it. Otherwise, the opportunity to ride like a ball in a washing machine drum will not please you at all.
