I have inherited a 2007 Revive Giant bicycle blue and white. It has never been riden and kept in a Garage. I have all paperwork, manuals, and receipts from the purchase. I have no clue how much I should sell for. It is a loaded bike with a shift internal shift hub and cycling computer. Any help would be great. I don't ride bikes and neither did my dad. I think he bought just because it was cool t the time.
