Help on sizing
 

Hey everyone, i used to do alot of biking, but havent in a few years. when i did bike, it was with the walmart type bikes, i would always end up breaking the gears and the bike would fall apart in a month( not riding often) i would like to get a full suspention bike, but i can do just the fork suspention. also im 5'11 i read a frame 18 would be good for me, but im also 215 lbs, with an athletic build. i was wondering if you guys had a good bike that was in a good price range, 500. that would keep up, maybe just anything not from walmart would work..... i dont know, i want the suspention to keep up (biggest worry) thanks for the help.

I was looking at an airborne, or like a deore both between 4-600
