Co-Motion Tandems


Co-Motion Cycles has been hand building top quality tandem and single bicycles in Eugene, Oregon for more than 25 years. They are unsurpassed in quality, durability, and reliability. Their bikes are carefully and professionally designed to provide the most reliable and comfortable ride possible. Bikes can be purchased coupled, with all the necessary accessories for trouble-free travel. Co-Motion has also perfected the union of Gates carbon belts with internally geared hubs from Rohloff and Shimano, to produce bikes that enable worry-free traveling and touring. We are very proud to represent Co-Motion Cycles; we have several Co-Motion bicycles in our own personal fleet and ride them regularly for recreation, rallies, tours, and travel.

To check out the full line of Co-Motion bicycles and accessories, visit the Co-Motion website.

Atoc and Draftmaster Racks


We believe that Atoc and Draftmaster racks are unsurpassed by anything else on the market in terms of design, ease of use, and durability. Atoc racks are car-top racks while Draftmaster racks are hitch-mounted. We can work with you to determine your specific needs and then to design the rack set up that will best meet those needs, giving you the capability and flexibility you want for carrying your bikes, including tandems, singles, triplets, recumbents, and trikes. We can put your order in to Atoc/Draftmaster. We can assist in arranging shipping, or if you are reasonably local, we can pick up the new rack system from Atoc/Draftmaster for you and help you to set it up.

To see all they have to offer, check out the
Atoc/Draftmaster website.

Service


The Rohloff enclosed hub, coupled with Gates carbon fiber-reinforced drive belts, has proven in our experience to be an excellent drive train choice for tandems and single bikes, not only for travel, but for everyday use as well. These systems require very little in the way of regular maintenance - periodic hub oil change and cleaning/conditioning of the belts is just about all that is needed. Our service menu is mostly directed at the Rohloff drive train. Click to check out the service offerings at Tandem Diversity.
