Hey Jesse ,
Nice Score !!!
I think the seat may have taken a hard fall forward................Maybe , because I think It would be hard to ride that way
When I was young ( 10 or 11 ) I started riding Unicycles . Had a Two wheeler as well . Was constantly on one or the other. Actually my first weld job was on a home made Unicycle. I took a regular girls frame , and chopped it up for a vertical set up. I had always wanted a "Tall" Unicycle ..............but could not afford one. Soooooooooooooo Why not make one . My Neighbor had the saws and welder..............and I went to work. This ended up looking like the ones you see with a Chain .............As a young boy.........I forgot to do something . The Coaster set up was retained , instead of converting to direct drive.............Well , I rode it , and long distances too....................Coasting sometimes...............and using the brake to keep upright ! What a learning experience !
