Thanks for all the advice guys!
yeah I guess I can just get new tires rather than change the whole set up.
I'm just really fond of that bike set up. it reminds me of a bmx.
Does anyone know what those bikes are called? maybe i can find one around craigslist of ebay.
I need to replace my back rim as well, so if anyone knows any nice quality single gear back tires that won't run me too much please help!
