the brawler is a low end bmx bike. not what i would recommend for serious riding. mongoose make some good bmx bikes, the brawler (or the sniper for that matter) isn't one of them. sure they are good for the money, but as far as quality goes, there are many better bikes around, but they will also cost you a bit more. there are a few things that let the brawler down as far as quality goes. they are:
single wall rims
loose ball bearing hubs (looseball hubs aren't that good. i'm regularly fixing them)
doesn't have a full cromo frame (makes it weaker and heavier than a full cromo frame)
plus a few other little things. but most of these are common things with bikes of that price range, and the only way to get the better stuff is to spend more money.
