Look for a good mountain bike with a solid wheelset. I am a big rider, 6'4" 285 and I ride an aluminium frame mountain bike and it works really well. Get some tires that are semi-slick and it will make your riding on the road and hard pack trails much more fun. Good luck.
That is a heavy duty frame. The largest size has a S.O. height of 31". The Karate Monkey largest size has a S.O. of 34". I am sure he would have to extend the seatpost on either one. I was just pointing our the different measurements.
