I'm at the same height than you. Most my bikes are 18" or 19". I would never go beyond that, though. If you intend to do some real mountain biking never buy a too big frame, though. My Kona from that same era is 19". When in doubt, ask if you can try the bike first. Bikes and shoes are not something you can buy just by looking pictures. Good hunting!
