Hey lazy web, my son has POTS which means his legs just go limp at random. Our house is not wheelchair accessible, he uses a cane. He likes to walk places but sometimes gets stranded by a flare-up. Obviously a bike or e-scooter is out of the question. Have you got any image references for a folding tricycle scooter?

ETA: to be clear the intended application is for going to the local shops, visiting friends, and bus trips to cinemas, malls etc.
