I’ve made plans to travel and am in a wheelchair. I’ve thought about how to carry luggage with me if I’m ever by myself and I’ve come up with a flimsy way of attatching a rolling suit case to the back of my chair with bungee cord and ties. My chair is similar to this: http://www.quickie-wheelchairs.com/produ…
It has curved bars underneath at the back where I was applying the bungee cords. My question is are there better ways of attaching a rolling suitcase to the back of a chair, so it can be attached and unattached quickly, and so that the chair can still be folded when the suitcase is unattached (so nothing permanent like a metal bar mounted on the back), and also something sturdy so the suitcase doesn’t hang to low and drag on the ground.
In addition, if you’ve carried luggage and are in a wheelchair, what other methods did you use or advice can you offer?

Put a Back Pack rack on the back rest of your chair and carry all your stuff there. Remember not to go where your chair is in danger of tipping. Good luck, I envy your courage and drive.
When I do go out for a trip the bag I use is a Large A.L.I.C.E. bag on a frame. It carries 70 – 100 pounds of gear or supplies. It ha some 3800 cubic inches of storage. . Made of 420 denier nylon. I simply attached it with the shoulder straps over the handbars on the back of the chair. I used bungees to lift it up. As far as suitcases on wheels I know of no case that they hold up that long, and they have a habit of tipping over.
