Connie and I decided to try tandeming. We thought we might encourage each other to exercise on the bike and that it would be fun. Tandems are expensive. We decided to buy an entry level bike to make sure we liked riding a tandem before buying a really expensive, nice tandem. The KHS bikes fit the bill. We purchased this one from Any and All Bikes in Denver.
