Illustration for article titled 1873 Monocycle Replica Is a Mechanical and Engineering Marvel

This monocycle replica from 1873 is an stunning engineering and mechanical feat. Created by a spaniard using 19th Century documentation and old-style handcrafting techniques, it uses a 6.16-foot wheel, with a 238-teeth inner segment. As you can see in the gallery, the quality of his work is simply amazing.

This man from Burgos, Spain, created the whole thing by himself, casting the main bronze wheel from a carved oak model. He also used different steel alloys for different parts of the mechanism, depending on the stress they are going to suffer. The saddle's suspension bar was treated in a forge to obtain the necessary elasticity to make it work right.

The bidding starts at $13,000 and given the quality of the work, I would pay that and more (if I had the money, that is.) [eBay via Boing Boing]

that spiky gear looks awful close to his family jewels, i hope he doesn't hit a curd or anything that would cause him to lurch forward into that. Other than that I would love to make one, that would be awesome.
