A closer look at the Vektron S10

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.

Updated Vektron Frame

RE-ENGINEERED FOR A BETTER RIDE

With a re-worked frame and frame geometry, the updated Vektron is now even better. The cockpit is longer for improved comfort for taller riders. The frame has been designed with additional forged and machined elements for additional strength without extra weight. The battery now reclines backwards, keeping the center of gravity as low as possible for superior handling. And the new design allows the Vektron to stand up vertically when folded, making it even easier to roll around.

DoubleTruss™ Technology

Extra stijf dankzij 3D constructie

Af en toe- denk aan een hangbrug- zijn de meest functionele constructies ook de mooiste. Onze DoubleTruss (tm) frameconstructie is de perfecte verbinding tussen vorm en functie: ontdek het als je de lichte en elegante TERN uitvouwt.

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.

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

De maat voor stabiliteit en stevigheid

Niet minder dan vier onafhankelijke patenten zijn bij de ontwikkeling van de extra stevige stuurpen verkregen. Daarmee is elke ver- draaiing tijdens het rijden praktisch uitgesloten. De stuurpen is 3D- gesmeed uit een stuk alu-minium, dus geen lasnaden of zwakke punten. Onze veiligheidsknop fixeert de stuurpen auto-matisch, op het moment dat de hevel gesloten wordt. Zo is je vouwfiets blind te vertrouwen.
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.

Porter+™ Saddle

CARRY YOUR BIKE COMFORTABLY

We reengineered the underside of the age-old bike saddle into a comfortable grip and shoulder pad. Up top, the dual-density construction and gel cushioning will keep you comfortable on the road, and the impeccably finished vacuum construction makes the saddle waterproof and easy-to-clean. Down below, the GripPad™ on the underside of the saddle lets you grip the saddle nose with comfortable confidence when your rolling your folded bike.

Telescopic Seatpost™

LONGER SEATPOST. SMALLER FOLD.

This seatpost is perfect for tall riders or anyone who likes a compact fold. It extends 90 mm longer than our stock seatpost, but thanks to its unique design, it’s 120 mm shorter when retracted. It features a dual-bolt head design for precise saddle adjustment, and an inner post diameter of 27.2 mm, so you can customize it with other posts.

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.

Shimano Deore Shadow+ Derailleur

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.

Valo™ Direct Light

Immediate illumination

Our 41 lux, 150 lumen Valo Direct lights up your ride without adding the drag or weight of a dynamo. It’s engineered to sit inside the handlebar stem, where it’s safe from knocks, bumps, and theft. That means it’s protected while folding, and optimally positioned to give you the most light.
Herrmann’s Expertise
We designed the Valo with Herrmans, the Finnish lighting experts who have a side business making lights for massive earth tunneling machines. No surprise then that the Valo is ready for all weather conditions: it’s made from cold-resistant ABS with built-in water management channels.
Extra Bright
The Valo puts out 41 lux of light, 4x brighter than the European requirement for bicycle lighting. That means you get a bright, wide beam of light that makes cycling at night safe and reassuring.
Clarity™ Optics
The Valo has a carefully shaped mirror that optimizes the beam pattern for cycling. It is wide, so you can see potential obstacles or hazards on the side of the road. It is even, without hotspots, so your night vision is not compromised. And it is clipped at the top of the beam pattern so you don’t blind oncoming cyclists or motorists.
Side Lighting
The Valo has light channels on each side so that you are visible to cars approaching from the sides. For additional safety, the Valo has two additional LED’s on each side, which light up when you’re stopped at a traffic light.
Visor
The Valo protects your sensitive night vision with a small visor that blocks light from shining back into your eyes.
Patented CryoCore™ Design
LED lights need to run cool to work optimally. If they run too hot over a period of time, they gradually lose brightness. Most LED lights have a tiny button sized heat sink that is used to dissipate heat. Our patented design connects the Valo to the handlebar so the entire bar is used as a massive heat sink.

720° Visibility

See and be seen

You need to be safe when you’re out on the road. That’s why we’ve designed our hard-core commuter bikes with 720° Visibility: 360° of active lighting and 360° of reflectivity.
360° Active Lighting
Specially designed lights allow you to be seen from all angles when it’s dark out. Accidents often occur at 90° angles at an intersection so active side lighting is especially important.
360° Reflectivity
Bright car headlights can overwhelm the active lights on a bike and this is why reflectivity is important: the brighter a car’s headlights, the brighter the reflective patches shining back at the driver. Bikes with 360° Reflectivity are visible from every angle to oncoming cars.

Atlas Rack

AN ULTRA-ROBUST RACK WITH GSDna

With structural cues from the heavy-duty Tern GSD, the new Atlas Rack has been massively strengthened and increased in size, with a load capacity of 27 kg (59 lb). This reduces flex for more secure handling when the bike is loaded. Riding with your little one? Add a Thule Yepp Maxi or Nexxt Maxi child seat—no adapters needed. The Atlas Rack is also KLICKfix-compatible, and can hold panniers of different sizes—including the Bucketload Pannier, which was designed to fit every configuration of the Vektron.
