I was given a motobecane frame of unknown year [I'm thinking late 70s to mid 80s] and it had an English thread bottom bracket. I also have a Peugeot that was given to me. There's not much to be said about these bikes. They're sturdy and cheap. The Grand Touring I believe is another "bike boom" bike made of mild steel. So, it's a tank, but if it works, use it.
