Does anyone know who built the Auto Mini folding bike? Headbadge says Executive. Made in Austria. I have a couple of Raleigh Twentys and they are quite a bit heavier than the Auto Minis. The plate that the rear brake and fender bolt to has ESGEE and Pletcher stamped into it. It has a different 2 piece pedal system. Where the one pedal arm unbolts(w/cotter). Just wondering because I have 5 of them and if they're worth fixing up. I have a few other folders as well. No Stridas or anything like that. All older.
