Tern OCL Frame Joint for folding bikes

OCL Frame Joint

Advanced folding technology

The key to any folding bicycle is the frame, and specifically, the folding joint at the heart of the frame. Done well, it locks the two halves of the frame together without any hint of movement or sound. It should be easy to operate and work flawlessly year after year. The OCL Joint does all of these things and is a new reference in folding frame technology.

Stronger by Design

Making the hinge taller and moving the pivoting surfaces outward from the center axis more than doubles overall strength and stiffness. It’s a difference you’ll feel from your very first ride.

Smooth Operation

The patented design puts four igus® bearings between the aluminum and stainless steel moving parts so the folding action is always smooth and friction-free.

Interlocking Joint

The front and rear joint surfaces lock together to eliminate torsional movement.

Easy to Use

Large rounded surfaces on the lever and joint bodies are easy on your hands and allow good leverage for easy operation.

Doubly Safe

Close the lever and the AutoLok automatically locks in place, for extra, easy security.

Floating Point Technology

Patented technology allows the lever to fold flat and brace against the joint for protection in transit.

Serviceable

Good things are built to last and that’s why the OCL Joint is designed to be dealer serviceable. We keep every part in stock and if your bearings ever wear out, your dealer can replace them in a few minutes.

Precision-Machined

A machining tolerance of only 50 microns ensures a tight fit and eliminates looseness and rattling.

Stainless Steel Hardware

Cold-worked stainless delivers the durability and reliability needed for daily riding in all weather conditions.

Tern DoubleTruss Folding Bike Design

DoubleTruss Technology

Stiffer by design

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.

Compac fold

Compac Fold Technology

Big bike, small fold

Designing an uncompromised full size bike to fold into a compact package is a difficult engineering exercise. Compac Fold technology let’s us get a 650B bike down to a usefully small folded package that can easily tossed in a cab, taken on a bus, or stashed in a coat closet.
