I am 6', 230, and ride both. I have an iron horse sgs, and a trek bruiser 2. My bruiser has nearly nothing stock on it anymore though. I have broken 2 handlebars, 3 forks, 2 sets of cranks, and one frame. The wheelset, brakes, seatpost, and rotors are the only things left from the original build. I ride mainly street, park and djs on it. Once you get past the drops to flat phase of urban riding the bike will hold up much better. I have gone pretty big on the bruiser, and even made some downhill runs on it. My current setup, Built for maximum strength, at the lowest cost. Redline bmx cranks, wellgo b-28s, gack usa 3" chromo bars, evil/e13 crown chainwheel/bashring, dj3, cheapo steel bmx stem, pig dh headset, ruffians, 6" avids, azonic big drop seat, and k-rads. I painted my warranty return frame black. Not too bad. It is holding up relatively well. I highly recommend the k-rads. They rule the world for urban park and street.
