Tern N Fold

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.

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.

Tern Physis Handlepost Gen 1

Physis 3D Handlepost

The new benchmark

Four patented technologies and unique manufacturing technology add up to the strongest, stiffest 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 was designed with a massive joint knuckle and a post that gradually tapers from thick at the base to thin. The fork steerer interface is 150% more stiff 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.

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.

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 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.

N-Fold Geometry

The Physis features a unique patented geometry with a forward facing hinge for additional safety.

Schwalbe Big Apple Tires - Comfortable tires for folding bikes

Schwalbe® Big Apple Tires

Cush for your tush

Big Apples are special because they’re fast rolling AND super comfy. Sounds hard to believe but you’ll just have to take them for a ride to become a believer.

Faster Rolling

Wide tires roll better than skinny tires at the same tire pressure. Yes, it’s true! Big Apples are extra special because they use a light and flexible tread and sidewall for extra low rolling resistance.

Wide for Comfort

Super-wide Big Apple tires are like 2" of super-efficient suspension. They roll smoothly over drainage grates, train tracks and potholes with little complaint.

Puncture Protection

Big Apples feature a Kevlar belt to protect from punctures.

Reflex for Safety

Each Big Apple tire features a reflective stripe so you are immediately, and obviously, visible to cars approaching from the side.
