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.

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.

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.

Tarsus™ Fork

Hydroform meets function

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

Hydroformed Tubing

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.

Internal Wire Routing

If you decide to equip your Tarsus with a dynamo hub, it’s ready for internal cable routing, keeping the profile of your bike clean.

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.

Syntace VRO Stem

Kinetix™ Pro X Handlebar

Light and strong

At a feathery 160 grams, the Pro X handlebar is one of the lightest aluminum handlebars available. Multi-stage butted from 7050 aluminum and designed specifically for our VRO and Andros handlebar stems.

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.

The caliper design is both ridged and durable, and the non-corrosive mineral oil brake fluid is gentler on the environment than most hydraulic brake fluids.

Kinetix Pro X Disc Wheels

Rocket fast

Kinetix™ Pro X Disc Wheels are engineered from the ground up for speed and performance. With custom-forged bladed Sapim spokes, CNC machined hubs, and high-profile rims, they’re light, strong, and look pretty fine too. Even better, they’re 100% hand-built and hand-trued.

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 allow 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 built by hand from start to finish by a single wheelsmith. The wheelsmith goes through at least three cycles of truing and spoke de-stressing before the wheel meets our rigorous standards.

Kinetix Pro X Hubs

Pro X hubs are precision machined for perfect spoke alignment and roll on smooth sealed bearings. Front and rear hubs feature flanges that are closer together—optimizing the bracing angle for a smaller wheel.

EN Certified

The wheels exceed EN standards for strength and durability.
