hahaha this one is pretty amazing

"I when it gets loose I just tighten the bolts an for some reason it makes the chain almost too tight and bends the frame together slightly. I don't get it either it's a miracle basically I've taken this bike to three different bike shops and they told me its impossible to make it a fixed gear and it would cost over $600 to make it a 10 speed but I proved all those fools wrong and I went back an rubbed it in their faces like haha the back wheel was $150 and the chain was $20 so take that you snobby bike snobs"
