An eBay seller (whose first language is clearly not English) has hand-built a replica steampunk powered monocycle from the Victorian era. This is a hell of a piece of engineering.
After many dedication compiling information about books and documentation of epoch of the 19th century, 1got a base of knowledge to make this faithful reply of this unique monocycle for it´s funcionality and elegance.
It was invented in 1873 in France.
