Hi There, I'm new to the forum and wanted to get some information as to what's the best way to selling a New Diamondback Sortie Black 29er. The bike is still in the box and is a small (15.5") I won this bike at a charity event and simply have no use for it since I'm in Florida. What's a reasonable price that this bike will sell for and how much does it usually cost to ship. Kind of new to the whole mountain biking world.
