After not riding for several years my wife and I decided to try a tandem. After much research on this forum and other places we bought on a Cannondale Street Tandem for three reasons. 1: It fit both of us. 2: it rides comfortably and 3: although it was more than we had intended to spend it was doable. We plan to most of our riding in the near future in the neighborhood or on local bike paths. I have installed a Serfas tail light. what other items should we carry or install to get through normal emergencies?
