Watch This Crazy One-Wheeler Move, Spinning Wildly toward 70+ MPH

From Car and Driver

• Engineering students from Duke University have developed the EV360, a monowheel project that's very challenging to operate.

• The student team aims to get the EV360 to at least 73 mph, as that would give them the new land-speed record from Guinness.

• One experienced monowheel builder and driver calls them "crazy machines," which is a warning to some and an invitation to others.

The name EV360 can be seen as descriptive. In this case, since we're basically talking about an electric-powered circle, it's like an electric vehicle that wraps itself around you in 360 degrees. So far, so good since the EV360 is the name of a monowheel project conducted by a group of students at Duke University.

But if you picture a monowheel by thinking of the more straightforward description of a huge wheel a person can ride inside of, then it's a good idea to listen to Hunter Howell, who has built and driven a monowheel out of a giant truck tire. As cool as it looks, Howell's experiment is not exactly easy to pilot. "The monowheel is one crazy machine," he told Business Insider. "You give it too much gas, it's going to ride up on you. You give it too much brake, it's going to want to dive. You lock the brake up completely, and you'll start spinning inside of it. You'll go upside down." That warning gives the EV360 name a new and more worrisome meaning.
