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.

Biologic Joule Drive - bike dynamo hub

BioLogic Joule™ 3 Dynamo Hub

Make your own juice

A hub dynamo is the ultimate green power source because it generates electricity while you ride—no batteries or recharging required. The Joule 3 is one of the very lightest and smallest dynamo hubs on the market and is one of only a handful that exceeds the High Efficiency (HE) 70% threshold. Say goodbye to batteries. Winner of a Eurobike award, the Joule 3 meets German StVZO standards for a 6V/3W hub—meaning it can power both a front and rear light.

73% Efficiency

The Joule 3 is so efficient that there’s no noticeable drag even as it’s powering your lights. Most other dynamo hubs are much less efficient; the lower the efficiency, the more drag you feel when you’re riding.

Ultra Light

The non-disc version of the Joule 3 hub weight a mere 356 grams.

Disc Version

Available in 6-bolt disc brake version with 100 mm OLD.

Shimano Alfine 11 Hub

Valo Light: Dynamo-Powered Front Bike Light

Valo™ 2 Light

Floodlights for your ride

The Valo 2 is a powerful light designed to help you navigate safely at night. The unique design integrates directly into the handlebars of an Andros or VRO-equipped Tern bicycle so it’s protected from theft and damage. And because it’s hub-dynamo powered, you never need to worry about batteries or charging again. Flick a switch and you have instant 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 the Valo from reflecting 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.
