Odd-Wheel Wonders: 11 Novel Vehicles with 1 or 3 Wheels

3R-C Zero-Emission Motorcycle

If you’ve ever had the misfortune of being called a “third wheel,” chances are the circumstances weren’t exactly positive. In the case of Honda’s conceptual 3R-C, however, the third wheel is actually a benefit. The extra wheel on the all-weather bike gives it an impressive amount of stability, while the retractable roof lets riders decide whether they want bugs to splat against their helmet or against their windshield.

The Streetflyer

Combining a bike with running with hang gliding, the bizarre Streetflyer is certainly unlike anything the world has ever seen before. The three-wheeled, non-motorized contraption requires the rider to run in order to get it started. After that, momentum will carry it along for a while before some more running is required. It may look odd, but it seems like a pretty good way to get around – provided there are no hills to run up.

The Solowheel


The Solowheel might be the ultimate in minimalist transportation. It is, as the name implies, a single wheel. The user balances on the footrests on either side of the wheel and leans forward, Segway-style, to make it go. The battery can go for about two hours on a single charge, and when you’re not riding around the streets feeling cooler than everyone on two or four wheels, it packs up into a neat handled, easily-carryable package.
