We custom-built this extra small Co-Motion Primera tandem in 2005 so that my 5'1" wife could ride with the kids. Unfortunately, our rotten kids never became tandem enthusiasts, so the tandem has low mileage and is in mint condition. Now my wife has health issues that prevent her from riding and we are selling the bike for $2,500 (which is below market value according to the online price estimator). This tandem has a 27-speed Ultegra drive train, the performance package upgrade, and many extras. It is perfect for two small riders. Contact me for photos and a complete specification sheet.
