I have a purple bianchi folder, it weighs a ton, the wheels on it are off a BMX, and need to be replaced, as do the other components. I fixed it up with a 52t engagement ring, bolted it to the one piece cranks and have a halfway decent little folder. I want to build those wheels, maybe over winter, and get the right seat post, and handle bars, of course this is money I don't have at the moment, but I have the bike.
