9 Absurd Transportation Modes that Never Got into Gear

by Kenn McCracken

1. The Monowheel

In 1869, French craftsman Rousseau of Marseilles built the first in history's line of unsuccessful monocycles. Sitting inside the monowheel, a rider steered the contraption by shifting his or her weight in the desired direction. As if that wasn't difficult enough, the massive outer wheel remained directly in the rider's line of sight at all times. Braking was also potentially hazardous, as stopping too abruptly would cause the rider to be propelled forward along with the outer wheel. But perhaps the biggest strike against the monowheel was the immediate comparison of any rider to a gerbil—something even the French wouldn't tolerate.

In 1988, Czech-born architect Jan Kaplicky attempted a feat that flew in the face of all odds: bringing change to Britain. The Superbus was a sleek, aluminum-bodied craft that charged itself at bus terminals and had the ability to lower its frame at stops to make it easier for passengers to enter and exit. The design was rejected in favor of the traditional red, double-decker Routemaster buses long associated with London's public transportation system. Was the Superbus truly hideous, or was it just one step closer to the 20th century and a decent dental plan? We may never know.
