Tandem mountain bike set up for parent/kid rides. Front is large and best suited to 5'10" or taller. Rear is good for adults or younger kids with step through frame. Rear cranks professionally tapped by Fairfield Cycles to allow smaller legs to have a proper pedal diameter. Marzocchi Bomber M2 forks up front. Tandem wheels with road tires. For such a big bike it is very light and easy for one person to lift.
