That's a neat idea, but I'd hate to have to find a place to carry it on my bike.

I have several of aluminum bikes with kickstands.

One is even that clamp-on old standard. The others have bosses on the left side chainstay that accept a standard mount. No reason to re-invent, unless you bought a bike that cannot accommodate either.

Guessing you've never tried/learned the pedal stand technique. Once you learn how to do it, you'll be surprised how many six-ish-inch-high curbs, etc., are conveniently placed for temporarily parking your bike.

Somehow, in over 50 years of riding I have never once wished I had a kickstand on my bike. There always seems to be some other (and usually more stable) way of parking my bike. Leaning it against a wall, tree, fence or post never seems to fail me. I can’t recall stopping anywhere without at least one of those options available. In which case I would just lay it down, as I often do when stopping on a grass field.
