could somebody take some time, and have a look through here and just see which bike would be best for me, i should have around £500 to spend, i want at least a back brake, because me without a brake is just death. I could probably stretch a bit more money but thats probably all i'm getting. Preferbly somebody, that knows a fair amount about bmx's, i know that bongo, poopipe, and OBM know there stuff. Thank you, please.
