I picked up this bike for a very small sum of money at a tag sale, but I can't figure out what kind it is. The only really distinguishing features are that it is a six-speed (one large chainring in front) and the shifter is mounted on the down tube. I've attached the logo sticker that's on the frame (sorry for the low quality, the room where the bike is has awful lighting).

I don't even know if this belongs in the vintage section, but the bike seems to be rather old and still in good working order. So is this just a really cheap brand or something better?

Thanks,
Andrew
