Handcrafted Wonder: 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.
