The 1910 Edison-Puton Monowheel

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 1910 Edison-Puton Monowheel on show at Cholmondeley has the frame, rider and a 150cc De Dion engine enclosed by the wheel.

A look back through history shows that at least 40 major monowheel projects have been undertaken between 1867 and now, and though many have displayed sheer engineering genius in order to bring them into vague usefulness, very few have seen service as genuine transport enablers.

The Edison-Puton Monowheel normally resides at the Auto & Technik Museum at Sinsheim, Germany.
