If you want the cheapest, and you are talking about like walmart or atrget, Huffy Cranbooks are oftern sold for less than 100$
They are easy to cutomize, cheap, and good riders if you take some time to regrease and give the bike another inspection after purchase.
Member CRASH sent me a link to a website that I cannot find in my PMs for the life of me. Black spokes, measured, cut and threaded ran me pretty cheap.
I did, it looks a bit rough in the pics, looks much better and tighter in person.
I'm kind of obsessed with 24" rides right now, I have my cwc frame lying around too, I might take apart my schwinn trike and use the rear axle on it for the build off.
I don't dislike Mike Wolf, and I think it's silly to blame HIM for the increase in bikes/parts. I am just not a fan of Felt bikes, I'm not into the new/retro look, their bikes remind me of the new mustang/camaro/challenger cars out there today, just not a fan of that look.
