Hitch attaches to the frame.
Based on using wheelchair wheels. (I have already secured a wheelchair that will be cut apart for my use.)

The wheels are my question. They wheels are the typical plastic/resin/whatever material with a chromed metal 'hand rail' attached. Does the hand rail thing add any structural benefit? I am liking the idea of removing it, but really it would be removing them for purely cosmetic reasons. I don't want to weaken the wheels just because I think it will look better without the handrail.

I keep going back and forth on my opinion:
1) Yes, since it is metal and bolted on at every 'spoke', the wheel is design with the added structural stability of the hand rail factored in.
2) No, the wheel will be plenty strong without the hand rail. The hand rail is purely functional and not structural.

Anyone want to weigh in?
I got hold of several wheelchairs for this purpose, and all of them had wheels that are strong without the "hand rail". I found the wheels a bit big so I built new wheels around the hubs. I built a flatbed much like the Y-frame from Carry Freedom. On a recent tripp we needed something smaller so mowed the atachment point further back on the flatbed and used the wheelchair axels to fit smaller (12,5") wheels.
