me any a friend are looking for a 20" wheel set thats really cheap. not bent in any way. and can use a 1.5 tire.
I remember a nimbus freestyle wheel at unicycle.com… I will look it up for you.
Here, the Nimbus II 20-inch, 36-Spoke Wheel ($41): http://www.unicycle.com/shopping/shopexd.asp?id=757
If you started with that, you could probably get a used tire from someone, buy a cheap tube at Longs drugs or something, and buy new or used cranks.
I think that would be a good way to go.
Also, you could check with Darren Bedford and see what he’s got.
Good luck!
Later,
Jess
