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.

Syntace VRO 47 Adjustable Stem for Tern folding bikes

Syntace® VRO Stem

Find your fit

Your bike should adapt to fit you―not the other way around. This adjustable stem allows you to position your handlebars further, for a more stretched and aggressive riding position, or up higher for increased comfort.

Adjustable

Stems are 47mm in length and infinitely adjustable so you can find your perfect fit.

Syntace quality

Syntace is a boutique German company renowned for their best-in-class bicycle components that are selected by many champion professional riders. They are perhaps best known for their manic attention to detail and brutal testing standards.

Light

Only 120 grams. 100% CNC machined from 6066 aluminum.

Strong

Two stems spaced widely apart means excellent torsional stiffness so go ahead and crank hard on your bars with confidence.

Syntace Stasis Seatpost

Stasis Seatpost by Syntace®

Light AND strong

The Stasis is based on Syntace’s renowned P6 design and is incredibly light, yet durably strong. It is forged from 7075 aluminum and hard-anodized for extra durability. Packed with smart engineering details that make the post easy to use and adjust.

Syntace Tested

Syntace testing is done on what they call the Red Monster and it exceeds the DIN+ standard which is typically used for freeride and downhill components. Needless to say, if it passes Syntace testing, its plenty strong enough for our bicycles.

Light

In the 33.9 x 580 mm size, the Stasis seat post weighs only 447 grams, lighter than many carbon posts of the same size.

Easy Adjustment

Syntace’s ERS technology delivers loads of fore/aft adjustment for the saddle. You can run the saddle forward for zero offset stiffness, or all the way back when you want more room to stretch in the cockpit.

Easy to Use

Two-bolt micro adjustment allows for an infinite number of saddle angles. Obsessive attention to detail means the bolts are angled outward at 40 degrees for easy tool accessibility.

Kinetix Pro Wheel

Kinetix® Pro Wheels

Faster by design

The lightest, fastest, 507 wheels available. ’nuff said.

Rolf® Paired Spoke Technology

Paired Spoke lacing allows us to use fewer spokes at much higher tensions, resulting in a wheel that is lighter, stronger, and more aerodynamic.

Self-Aligning Nipples

Sapim nipples have a convex surface that allows perfectly straight alignment of the spokes. This increases strength and durability by eliminating the most common type of spoke breakage.

Hand-Built

Kinetix Pro wheels are painstakingly built by hand from start to finish by a single wheelsmith. Each wheel goes through three cycles of truing and spoke de-stressing.

Top Quality Parts

Custom hubs from American Classic. Custom forged aero spokes from Sapim. Custom rims, with a proprietary aluminum alloy, from one of the best in the industry.

Light Weight

Less than 1 kg per rim.

Tern Magnetix for folding bikes

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.

Tern luggage socket for folding bikes

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 Tail Light

BioLogic TailLight

Two-in-one light/reflector

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.
