I'm 6'1" and now 212. I was 220 lbs when I started. I have a Dahon w 20" wheels and have not had any issues at all. The bike handles anything I encounter. I agree give it a test ride. For me, the bike was a tad nerve-wracking at fast speeds when I first started riding, but now it feels very natural and comfortable even at faster speeds. I climb hills and have a small section of trail on my commute. It's an old packed trail, short but the bike does fine. The streets I ride are heavily patched and bumpy. I haven't had any problems.
