Well Theres 2 choices... u can get a real bmx tool kit at
www.danscomp.com for 20$-80$ depending on how much u will use it and wat tools u will need or u can go out to any hard wear store and get a socket set an allen wrench set and a set a VICE grips. But to get the (freewheel) back sprocket assembly off u will have to go to a online mail order site or a bike shop. TIP: ASK FOR A FREE WHEEL REMOVER. -E
