kimo: I 'm a big fella too...310 lbs and 6' 4". I just bought a Sun EZ Sport CX with the Cro-Mo frame. I emailed one of the Sun customer service reps and he said the model I bought had a weight limit of 275 lbs., but they were actually designed to handle quite a bit more weight than that...product liability and all, you know. Considering I was riding an old Huffy cruiser bike and it held me up quite well, I figured the EZ Sport CX would handle my heft much easier. Of course, if you break a frame and you're over the published weight limit, then you're on your own as far as the warranty goes. I figured the risk of remaining obese was much higher than a broken bike, even a possible crash.
The bike weighs in the neighborhood of 40 lbs. with the fenders and rack, but seems to me to pedal much easier than the published weight would indicate. Some get really obsessed with bike weight, and to a point I can agree since climbing hills is about nothing but weight. Still, I figure that me losing 100 lbs. will have much more effect on my climbing ability and comfort that a pound or two on the bike. Don't get me wrong, when I finally wear out a component, I'll upgrade to something better, but not at the expense of reliability and durability. The only change I may make is to some Aerospoke wheels with disc brakes when I'm in good enough shape to tour.
As far as my climbing experience goes with the CX, I've got some small hills in my neighborhood and one pretty good one. The climbing isn't difficult, you just have to have a different approach than on the DF since you can't stand over the pedals. You just have to get into that low gear and work your way up the hill in a good spin. I find that on the hills I ride, I can spin up the hill pretty well at 90 to 100 RPM. Not so fast that it's hard to ride clipless and not so slow that the quads start to burn from pushing too much. I REALLY like the bike I bought. I haven't had this much fun in years. Good luck with whatever you get. BBJ
