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.


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.


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.


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.


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.


BioLogic Arx™ Grips with T-Tool

There when you need it

BioLogic Arx grips are quality, ergonomic grips designed to put your hands and wrists in a comfortable position. But they have a hidden secret—a 4/5/6 mm Allen tool hides in the right grip. It’s there when you need it, out of the way when you don’t.


BioLogic PostPump™ 2.0 Seatpost

Be Prepared

You’ll always be prepared with this high-capacity floor pump hidden inside your seatpost. A true floor pump, it delivers a much higher volume of air than traditional mini-pumps, and the pumping action is easy—great for those high pressure or large volume tires.

High Volume Capacity

Only 40 strokes to reach 50 psi in a 20″ × 1.5″ tire

High Pressure Tolerance

The reversible presta/schraeder chuck screws securely onto tire valves—a nice feature to have if you’ve ever experienced a friction fit chuck popping off while you’re inflating a high pressure tire.


The stainless-steel foot stand allows you to use your body weight and gravity to do a lot of the pumping work.

Invisible to Thieves

With your high capacity pump stashed invisibly inside your seat post, you’ll be much safer from thieves.


Schwalbe Marathon Supreme Tires

Urban rubber

Fast rolling. Superior puncture protection. Excellent wet grip. The Marathon Supreme is the ultimate commuting tire.


BioLogic FreeDrive™

Clean up your act

The BioLogic FreeDrive fits around the chain and keeps grease away from your pants. The unique design moves with the chain so there’s no extra friction.


Magnetix™ 2.0

Keep it together

The Magnetix 2.0 uses powerful magnets to keep your bike folded for situations like carrying your bike up and down stairs. With a pull force 10-15 Kgf, the Magnetix 2.0 will keep your bike folded even when being jostled and moved about.


Luggage Socket™

Carry more stuff

Fix the Tern Luggage Truss to the Luggage Socket and you can plug in your choice of front luggage : rack, basket, or bag. If it’s KlickFix compatible, it’ll work.


BioLogic TailLight™

Two-in-one light/feflector

A combination LED light and reflector sits up high on the rear of your saddle to make it visible to cars coming up from behind. The bright LED light lets you switch between blinking and steady modes.
