Innovation! Patent news
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. |

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.
