My husband and I both enjoy riding. He can manage a lot more speed than I can, but we'll both do 40 miles on a nice day and 60-100 mile days for charity rides. We've joked for many years that we value our marriage too much to try a tandem.
Yesterday, while visiting a local bike shop, we saw a tandem that was pretty enough it took our breath away. Already had couplers installed. He and I looked at each other, and after we controlled our drooling we got out of there before we did anything irrevocable.
Fortunately, we live in a tourist town, where we can rent a tandem for $50/day. Of course, the rentals are kitted out as cruisers-for-two; I'm more into tourers, and he prefers a racing geometry.
If we take a test ride, what sort of things should we be on the lookout for?
