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.

N-Fold™ Technology

The faster fold

With N-Fold Technology, Tern bikes fold small and fast—in three easy steps. It’s simple enough for anybody to master. And with the handlepost folded to the outside of the package, Tern bikes can also roll when folded for easy transport.

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.

Quadric™ Dropouts

THE USER-CENTERED DROPOUT

Dropouts are often overlooked, but a good dropout goes a long way. Our Quadric dropout is built taller, so your disc brakes are protected inside the frame. The design makes the eyelets for mudguards, racks, and our clip system more user-friendly and accessible than ever before. We even included a mount for a sturdy rear kickstand.

T-Tuned™ Geometry

Feels so good

At Tern, we endeavor to build fast-folding bikes that ride like full-sized bikes. Our T-Tuned geometry is the culmination of our commitment. We’ve tweaked the wheelbase, rake, and seat-tube angle on our bikes with T-Tuned geometry to deliver a remarkably confident and stable ride. Ride one and try it. Take your hands off the handlebars if you’re feeling bold.

Tarsus™ Fork

Hydroform meets function

Utilizing a single hydroformed tube mated to a precision machined steerer, the Tarsus delivers outstanding strength in a shape that matches the sophisticated lines of the Verge and Eclipse frames.

Hydroformed Tubing

Internal Wire Routing

The process of hydroforming aligns the grain structure and strengthens the aluminum material. It also minimizes welding in the most highly stressed area of the fork.

Physis™ 3D Handlepost

The new benchmark

Five patented technologies and unique manufacturing technology add up to the strongest, stiffest folding handlepost available. The Physis uses a special manufacturing process called 3D forging, which forms the post from a single piece of aluminum, eliminating all welds.

No Flex

To eliminate flex, the Physis uses a massive joint knuckle and a post that gradually tapers from thick at the base to thin. Moreover, it has 150% more clamping height between the fork steerer and the handlepost than common designs.

Flux Technology

The base of the Physis is machined so it functions as the upper race of the headset. This patented direct integration contributes to the incredible stiffness of the design.

Interlocking Halves

Joint surfaces lock together to improve torsional stiffness. We've fine-tuned the shape to virtually eliminate squeaks.

Redundant Double Bolts

Two bolts clamp the Physis to the fork steerer for improved safety.

igus® Bearings

The patented design puts sliding bearings between the moving parts so the folding action is always smooth and friction-free.

Large, Smooth Lever

Large rounded surfaces are easy on your hands and provide good leverage for easy operation.

AutoLok Technology

Close the lever and it automatically locks in place, for extra, easy security—using an aluminum pin.

Floating Point Technology

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

SpringLock Technology

Patented SpringLock technology holds the adjustment rod firmly in place so the locking lever is always properly tensioned and can never vibrate loose.

Serviceable

Good things are built to last and that’s why the Physis is designed to be fully dealer serviceable. We keep every part in stock and replacing the bearings can be done in minutes.

TriSeal Design

Three rubber seals keep weather out and the headset bearings functioning smoothly.

Precision-Machined

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

Stainless Steel Bolts

Cold-worked stainless hardware delivers the durability and reliability needed for daily riding.
