More information would be nice. Is it a hybrid, road bike, mountain bike?

If this helps, I sold my 1989 Bianchi Brava for $250. It's a lugged steel 12 speed road bike with downtube shifters. It had newish tires, chain, and cables. Hubs and bottom bracket were also rebuilt. The bike was in flawless mechanical condition.

Also the Classic and Vintage forum may be able to give you more help.
