I have had a BB-hinged folding bike frame in the works for years, though I don't travel often enough to have been motivated to build mine yet.

I find it very unlikely that there isn't a pile of prior art for this patent.

While a folding bicycle that requires the removal of the front wheel
might be okay for transporting a bike in the car trunk, they are not
practical for use on public transit. Montague has such a bicycle though
it folds around the seat tube. I have never seen a folding bicycle that
folds around the bottom bracket.

Now that 2-piece cranks with cylindrical spindles are a kind of norm, it makes sense to regard the spindle as a possible hinge pin. I've been using BMX cranks with straight spindles for a couple of decades longer than Hollowtech II has been around, so it also makes sense that I thought to do it earlier.
