I was wondering if any of you folding bike owners are Big/tall people, I'm talking 6'0"+ and say 250lbs+ size.
I'm really interested in getting a folding bike, but I don't know if the bike can handle my weight for one,
and two be comfortable to ride. My dimensions are 6'3" around 280lbs.

If the weight is too much, can I just replace the wheels and tires to support my larger size? I don't see why not?

I've ridden several normal off the shelf mountain bikes at my current size, if not heavier and had very few problems.

I've been looking at several different brands of folding bikes: Dahon, Downtube, Citizen Bike, Tikit, and Birdy.
They all look like great folding bikes, but all list very low max weights on their spec sheets.
Have they just not been tested on heavier weights or are these folding bicycles simply not
for bigger people?

Any information would be most helpful.

Thank You.
