From the specs page at the link:It's probably this:
...
Max rider weight : Over 800 lbs (363 kgs)
My guess now having seen it, is that unlike high capacity wheelchairs and the like, it is only incidental to the construction and not specifically designed for people that heavy. They built it and then tested it to the breaking point, with 800 lbs being minus a safety margin rounded down.
Either that or designed to carry passengers.
