One that works lol,mate this is all new to me so style? looking something to have a bit of fun with,i sold my nitro,but my 2 boys still have there wee nitro ones so its just something to mess about with them.something thats decent basic to start with then can upgrade parts,just ive another hobby collecting and building old school 80s bmx's have approx 14 built and another 20-30 to build and more coming from the U.S,so its a really expensive hobby.
