This is my first tandem after bike riding 50 years. It arrived undamaged, and was OK to assemble except for the seats. There are two different stem post sizes with no explanation. Neither fit without bending tubes. Overall, I was impressed by the finish and parts for the price. Except the brakes... they are an old fashioned sidepull pads and weak for this size and weight over 400 pounds with 2 riders. To compound the problem the brake levers are on the ramshead bar front only and hard to reach. To shift you must move the brake levers, also awkward. It is a good buy, but needs a lot of getting used to and riding away from any traffic hazards due to the brakes.
