A close look at the S+S Machine Bicycle Torque Coupling reveals the expert engineering that allows the system to work so perfectly. Interlocking tapered teeth are drawn together by a threaded lockring, providing an extremely rigid joint with minimal tightening force. The extremely durable, attractive and reliable S+S Couplings used by Co-Motion Cycles are of hardened stainless steel, and are silver brazed onto the bicycle tubes. In fact, a well-made BTC-equipped bicycle frame is measurably stronger than an identical frame without Couplings. As the leading manufacturer of S+S Coupling equipped bicycles Co-Motion Cycles has the expertise to make sure that your travel bike is without equal.
Because we know you expect the best, Co-Motion Cycles uses only the original stainless steel S+S Couplings. Many other builders are now using plated or non-plated couplings made from non-stainless material, which are designed to reduce cost and speed up bicycle production. Stainless S+S Couplings assure a lifetime of flawless and corrosion-free operation. We know that once you own a Co-Pilot, you’ll want to keep it forever.
All Co-Motion coupler-equipped framesets include quick-release cable splitters to
facilitate fast assembly and disassembly. Splitters install on both derailleur cables
and the rear brake cable.
Naturally, the best reason to own a Co-Pilot is that you never have to leave your passion for cycling behind when you travel. Your Co-Pilot checks on as regular luggage, saving you money and hassles each time you travel. Best of all, you'll maintain your fitness and your chosen recreation while the world becomes your cycling playground. When you choose the Co-Pilot option, we’ll include coupler-integration in our specifically designed Co-Pilot Project Tubing. Couplers are located for ease of frame packing.
Packing your Co-Motion travel bike is simple, and you don't have to be a mechanical ace to do it right. In fact, the only unusual part on our travel bikes is the S+S BTC. Cordura nylon padded sleeves with a Velcro backing protect your frame inside its case.
Co-Motion blazed a new trail for travel tandems with a brilliant Six-Coupling system. Since the Co-Pilot Option tandem frames separate into 3 equally sized sections, the ultimate in packability is maintained while tandem assembly and disassembly is intelligently simplified. For example, there are no separate tubes to lose or accidentally assemble out of sequence. Another significant advantage is that there is no need to remove the fork. Plus, we strategically locate our couplings for unimpeded wrench access without knuckle-bashing interference from the chainrings. Our competitors simply overlook these details that make your packing job easier.
No tandem maker is more thorough than Co-Motion when it comes to engineering the location of the couplings for optimum frame strength. Each coupling is fully supported where it is integrated into the butted section of our exclusive zonally-butted tandem tubing. Our large diameter bottom tube is oval at both ends and round where it joins just one large S+S Coupling. This design provides the known structural benefit of a single oversized tube as well as lighter weight and the logical simplicity and ease of handling fewer parts. And yes, the round S+S Coupling is superior to the “oval coupler” offered by another manufacturer.
Whether you’re thinking of the Co-Pilot option for your new Primera, Mocha, Speedster or Supremo, be prepared for a pleasant surprise. The performance of the couplers is so impressive; you may end up sidelining the tandem you’re riding now.

Please Note: Most airlines stipulate a limit of 62 linear inches for "checkable" luggage. Linear inches are the sum of the luggage's length, width, and height. The luggage we offer for our Co-Pilot bicyles is 62 linear inches or less. The Hybrid Case, the Backpack case and both Hard Case models all measure 26"x26"x10", equaling 62 linear inches.
Many other brands of travel bicycles and cases that are now being marketed as airline checkable actually exceeed this 62 linear inch lugggage limitation. Larger luggage is subject to airline surcharges.

Hybrid case weight is 17 pounds
The Co-Pilot Hybrid Case combines the best attributes of the Hard Case and Backpack Case.
With a tough nylon outer shell, it's got rigid perimeter panels and pockets for protective materials. We fitted it with smooth-rolling wheels and a stowable Pullman-handle to make toting your bike around an airport much easier.
Compression straps and heavy duty zippers make travel safe and easy. (26"x26"x10"=62 linear inches)

Backpack case weight is 7 pounds
For tandems or singles, the Backpack Case offers the greatest versatility. Constructed of heavy-
duty Cordura nylon, this case is internally supported with an ABS plastic perimeter that Velcros in place, which
gives the case structure to protect its contents. You can carry your bike on your back using the
backpack straps, or use it carry other items once the bike is removed. When not holding a bike,
the backpack case collapses into an easy-to-store package. (26"x26"x10"=62 linear inches when full, approx. 28"x10"x3" when collapsed for storage)
Hard case weight is 17 pounds
The original Hard Case is made from tough PVC plastic to provide ideal protection for your bicycle.
The lid's interlocking perimeter and continuous hinge ensure that the contents stay inside.
Key-lock latches and a padlock hasp [Note TSA does not allow locked luggage, but twist-ties, etc. can be used on the hasp] add to security while the Pullman wheels and a pop-up
handle make navigation to the luggage counter effortless. (26"x26"x10"=62 linear inches)
