Gotcha. Well thanks for sharing. I really like how you did it. I’ve run into a similar problem just using upright superstands to park my bikes in the apartment. The stays on the fender go too wide to fit thru, so I have to just lean my bike with fenders.
One thing you might be able to do is back the bike into the spot and then tilt it backward as far as you can before the fender contacts the ground, and hook the top of the front wheel from there. It won’t be as upright as the others, but make take up a little less space than just backing it in and leaving it flat on the ground. Just my two cents.
