BikeFriday lists the NWT weight limit @ 230 lbs, rider + gear.
Brompton lists the weight limit @ 242 lbs, rider + gear.
It's 2024. There are any number of modern true folding bikes with 300 lb. weight limits. Quick fold, Amtrak-compliant, 1/3 cost of a BikeFriday.
True, but most don't have wide enough gearing, if just derailleur gearing. The Origami Bull frame comes with a front derailleur braze-on, and I've suggested to someone on here who appears to be a seller, to offer them turn-key with wide double crank and existing cassette, THEN it would be the equal of a Bike Friday. They said a month or two back, they would consider that.
