In regards to the Montague, I've been in email contact with Ryan at the company since I first started looking. He said any of their frames would hold up, he had concerns over the wheels. He suggested using using wheels with a 36 instead of 32 spoke count and a slightly wider than 1.5" width on one of the 20" mountain bike models would work best for me. So started this thread looking for a second opinion on a Paratrooper with beefier wheels.

Other manufacturers I emailed basically said "can't help you", except for Island Hopper from Florida that has a 350 lbs. rating on their folding bikes. Island Hopper doesn't seem to have a following and so other issues like customer support are a big unknown.

When I went to Bike Friday's site, I read the same info in the heavy build still only going to a max of 260 lbs. I didn't really bother investigating more at that point. I'm thinking that getting a Bike Friday build to fit would price it well beyond the Montague.
