Apparently there's a law pending against selling bikes with 20" wheels in NJ. It is intended against child bikes for some reason, but to make the language work they changed it to 20" wheels, not thinking adults ride folders and recumbents with 20" or smaller wheels. If you are in NJ, check it out and respond to your legislators:
