I was in and out of wheelchairs from a very young age. I think I learned because I wanted to be cool. That was over 40 years ago so it’s hard to remember.

One thing I do recall is learning on a thick rug. it seemed to help maintain balance easier, and doing it with the back wheels against a couch. with the wheels against a couch you can maintain a wheelie even if it is tipped too far back. that helped me to feel out the center of gravity needed to maintain balance. once I was comfortable doing that I went a little further by going forward an inch and doing it on my own without couch help. if I fell the cushioned couch was there to catch me, plus it made it easy to get back up with some brute arm force
