A friend of mine is thinking about getting into unicycling, but doesnt want to buy (We high school kids have fixed incomes, really fixed!). So he suggested he build one from an old 20 inch bike… Has this ever been done?! Like the frame would be easy, just use the front fork, and i have an old viscount seat i can give him, but what about the hub, would you have to buy one? Could you weld the spokes to the hub? Its an interesting idea, would be pretty fun too. Any tips would be great.
PS: Yes I know this would not be a very strong unicycle, but in my opinion, people underestimate the strength of hubs and frames. I have a Norco uni that i got for 150CDN, and i have done a lot of 2-3 foot drops, and A LOT of hopping, and its still in good shape.
