Then another guy (at a LAW rally) showed me a sort of multi-step plastic
wedge he'd cut out of plexiglass. He'd squeeze the front brake lever,
then cram the wedge into the lever's opening to hold that brake on. The
front wheel was then unable to roll and the parked bike was much more
stable. Blackburn picked up the idea and sold them for a while.

But they're easy to make.

For a while, there was a wire loop called a Flickstand for
immobilizing the front wheel. It worked very well, but was
incompatible with fenders and soon vanished.

Velo Orange sells a thing called a "wheel stabilizer" for $10 that is
supposed to keep the front wheel straight and works with a fender.

And apparently comes in different sizes to fit different down-tubes.
