It's been more than 100 years, and people are still gawking at the 1910 Edison-Puton Monowheel. The incredibly unique vehicle will be displayed at the 2012 Cholmondoley Pageant of Power in the U.K. The wheel that you literally ride inside of was built in Paris and is run on a 150cc De Dion engine. In order to make its appearance, the monowheel will be making the trip from its normal home, the Auto & Technik Museum at Sinsheim, Germany.
