First introduced in 1993, the S&S Machine Bicycle Torque Coupling (BTC) has revolutionized the bicycle industry and forever changed the image of travel bikes. Substandard folding tandems with non-standard parts have become obsolete. Only other Co-Motion tandems equal the ride of the BTC-equipped Co-Pilot tandem.
Co-Motion blazed a new trail for travel tandems with a brilliant 6-BTC system. Since the Co-Pilot tandem frame separates into three equally sized sections, the ultimate in packability is maintained while tandem assembly and disassembly is intelligently simplified. For example, the Co-Pilot has 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, the Co-Pilot's BTCs are strategically located for unimpeded wrench access without time-consuming crankset removal. These details are critical time savers that our competitors simply overlook.
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 triple-butted tandem tubing. Our large diameter bottom tube is oval at both ends and round where it joins just one large BTC. This design provides the best known structural benefit of a single oversized tube as well as lighter weight and the logical simplicity and ease of handling fewer parts.
Because we know you expect the best, Co-Motion Cycles uses only the original stainless steel S&S Machine Bicycle Torque 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 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.
Don't worry! Packing a genuine Co-Pilot tandem takes less time than little-wheeled folding tandems. Our three-section design and easy-access couplers keep your packing job trouble-free.
