Anybody ever sell a bike at the consignment area of the bike swap? I've got a few decent vintage bikes that I'm considering selling and was thinking the swap might be a good place to unload easily (I think they would likely go for $400-700 on ebay). Do bikes go for close to market value? I'm not looking to make a fortune, or break even, but if they are way underpriced then I'd rather just hang on to them. Any tips?
