We put together a bike out of my friend's spare parts today:
He didn't have a seatpost that would fit, so no seat for now.. haha
Also used a crappy old chain that's bent and not too safe.. should have taken out another link but he's buying a new chain tomorrow anyway.
Frame is an old specialized fatboy I think, wheels are just whatever came on the bike, bars are from a crappy walmart bike. The frame is fairly heavy, complete bike's probably like 35lb (needs better bars, and a seat...)
It works!
..until the chain falls off and you bust your balls. POS thing. But it was free.
