Where are you located? It might be a bike Giant sold in markets other than the U.S. and none of us would have seen it. I was a Giant rep for a while and could not tell you all the bikes they made.

Give us some pix! You have enough posts to do so.

*edit*

Ah, Google!


Looks like a pretty basic bike. I'm gonna guess 1990 and 38 pounds with that rack and basket.
