I'm selling this used Tandem Trek Design 2 person bicycle.  I've had this for less than ten years, and don't use it very often.  I'm not 100% sure about the year, I guessed on 1997 based on some information from a couple websites.
It has had a number of upgrades.  New shifters, sprockets, handlebar wraps, front and rear brake clamps, and an electronic odometer.  Also comes with two blue helmets, tire pump, and a custom built bike rack.  Everything included for $600.
Please message me if you have any questions.
