Life in Tandem. Simmonsohn channels Danish and Scandinavian influences across all aspects of design. We value the importance of practicality and functionality. Our designs promote group activities with the belief that we are stronger together.

Modern technology has continuously improved component and frame designs, because of this tandems are no longer considered a novelty item. Their resurgence in popularity is due to the very nature that they can be as well-built as modern high-end bikes, with all the same technical specifications. They have the ability to perform to the same level as traditional, two wheeled bikes if the riders require. Whether shared mountain biking or casual leisure cycling is on the menu, the rustic Simmonsohn range has a model to suit everyone's aesthetic tastes and practical requirements.

With a distinctive retro feel the Trondheim is a perfect touring companion for the couple who want to venture a little further for a little longer. Up front is a responsive, lightweight Cromoly fork. The upgraded 24 speed transmission system comprises of Shimano EZ fire push button gear shifters with super precise Shimano derailleurs.
