Tern OCL Joint - Folding bike frame latch

OCL+ Frame Joint

Robust folding technology

A heavy-duty update to our iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.

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.

Tern NVO Stem

NVO® Stem

Designed to adapt

Want your bars higher for more comfort? Lower for more speed? The ingenious NVO stem adjusts in seconds so you get the riding position you want. Even better, the tool for adjusting the stem is hidden in the handlebar.

Porter+ Saddle: Helps shoulder your bike

Porter+ Saddle

CARRY YOUR BIKE COMFORTABLY

We reengineered the underside of the age-old bike saddle into a comfortable grip and shoulder pad. Up top, the dual-density construction and gel cushioning will keep you comfortable on the road, and the impeccably finished vacuum construction makes the saddle waterproof and easy-to-clean. Down below, the GripPad on the underside of the saddle lets you grip the saddle nose with comfortable confidence when your rolling your folded bike.

Pedal Holder

Pedal Holder

QUICK-RELEASE PEDAL STORAGE

Our bikes come loaded with lots of wow features, but one of our enduring favorites is the quick-release pedal. Once removed, it gives you a smaller and more maneuverable folded package. This under-saddle pedal holder lets you keep your free-floating pedal conveniently at hand.
