The Tern Joe C21 brings Tern's core technologies to a bike with an amazing price and even better ride. With unique folding technology, versatile gearing, and comfortable tires, the C21 is the peoples choice. It folds fast so that its always easy to tuck away or take with you.
The rear half of Tern frames use a patented 3D structure we call DoubleTruss to build in extra stiffness. It helps resist torsional forces so our bikes flex less. That means increased stiffness and much better power transfer from the pedals to the rear wheel. The proof’s in the ride.
The FBL (Four-Bar Linkage) Joint is a tried and true design that keeps a frame securely locked. It features a forged and precision machined lever designed to offer a smooth surface for fingers. All other hardware is stainless steel for durability.
