Wrong size, wheelchairs often call them 25" and they're the 540iso, I've tried to find nicer rims in that size since my kids' raleigh cx24 came in that size and its such a random one. Managed to find nice road tires but not rims that weren't drilled for a hand rail. Also had to convert a bike from 547 to 540 so I've spent far too much time dealing with the goofy size.
