I mentioned above that I use something similar to the clickstand. I cut a tent pole down in size, put a rubber tip on each end so that the upper end would not scratch the frame. The upper rubber tip, I cut that down a bit to a triangular shape to fit in between the tubes better. As I noted above I also have to use an elastic or piece of velcro to lock the front brake so it does not roll.

When I made it , I used enough tent pole segments so that it folds up short enough to fit vertically in my handlebar bag. After I took the photo, I glued a short piece of two sided velcro on it so that I do not need to use rubber bands anymore to keep it in the folded up mode.

It functions well, but I find that I am rarely using it because I am either not bothering to get off the bike or I am searching for something to lean the bike against.

Stability, it might be better because the pole is set further out from the wheel. But it is easier to trip over that way.
