Local Bicycle Trader
Looking to buy or sell a used bike? Check out Local Bicycle Trader, an online classified site for bikes. They offer free listings (with up to five photos) and the site collects info on bikes for sale from other classified sources, as well. A quick search for bikes in my neck of the woods turned up a wide variety of bikes, including a three seat tandem. Prices ranged from $95 to well over $1000.
