Alas, I thought I'd find it THIS time, but to no avail. I'd attach pictures of the bike and maybe you can weigh in a little bit despite the fact that I can't find a serial number. Clearly, however, this bike was manufactured in Canada as is stated on a silver sticker on it. Additionally, there is rust on the bike but it's surface rust. Thanks for trying to help. Maybe you can suggest where the serial number might be hidden.
