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.
The key to any folding bicycle is the main folding joint. 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.
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.
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.
The front and rear joint surfaces lock together to eliminate torsional movement.
Large rounded surfaces on the lever and joint bodies are easy on your hands and allow good leverage for easy operation.
Close the lever and the AutoLok automatically locks in place, for extra, easy security.
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.
Cold-worked stainless delivers the durability and reliability needed for daily riding in all weather conditions.
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.
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.
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.
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.
Joint surfaces lock together to improve torsional stiffness.
Two bolts clamp the Physis to the fork steerer for improved safety.
The patented design puts sliding bearings between the moving parts so the folding action is always smooth and friction-free.
Large rounded surfaces are easy on your hands and provide good leverage for easy operation.
Close the lever and it automatically locks in place, for extra, easy security.
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 Physis is designed to be fully dealer serviceable. We keep every part in stock and replacing the bearings can be done in minutes.
Three rubber seals keep weather out and the headset bearings functioning smoothly.
A machining tolerance of only 50 microns ensures a tight fit and eliminates looseness and rattling.
Cold-worked stainless hardware delivers the durability and reliability needed for daily riding.
The Physis features a unique patented geometry with a forward facing hinge for additional safety.
The Andros is our patented adjustable stem that lets you set your handlebars where you want—no tools, no fuss. In just seconds you can set your riding position to long and low in a tough headwind, or upright and comfy for riding around town. You decide how you want to ride and the Andros makes your bike fit.
Patented quick-release, tool-free design is easy to operate.
The Andros design uses two stems, spaced widely apart for excellent torsional stiffness.
Accommodates riders of all sizes so one bike can be shared by multiple riders.
Stainless hardware and brass bushings for long-term durability.
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.
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.
Only 40 strokes to reach 50 psi in a 20″ × 1.5″ tire
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.
With your high capacity pump stashed invisibly inside your seat post, you’ll be much safer from thieves.
Fast rolling. Superior puncture protection. Excellent wet grip. The Marathon Supreme is the ultimate commuting tire.
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.
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.
The Valo 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.
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.
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.
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.
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.
The Valo protects your sensitive night vision with a small visor that blocks light from the Valo from reflecting back into your eyes.
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.
