Hi Costello,
I would think that you would be OK on most folders designed to carry luggage. Not sure what the Dahons are rated to carry with respect to luggage. My bike is rated for a 240 pound rider and 80 pounds on the racks, or 320 pounds. Sure would be nice to see more tailored machines out there. Japan has a lot of bikes for little folks, but that's about it.
Best,
P
