A closer look at the Verge S8i

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.

Andros™ Stem

Adjust to fit

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.
Quick Release
Patented quick-release, tool-free design is easy to operate.
TwinStem Design
The Andros design uses two stems, spaced widely apart for excellent torsional stiffness.

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.

Shimano Hydraulic Disc Brakes

All-weather stopping power

Shimano hydraulic disc brakes deliver powerful stopping power in all weather conditions with the touch of a finger.

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 8 Hub Gear

State of the art

The Alfine 8 is Shimano’s masterpiece of an internal hub gear, packing 8 evenly spaced gears inside a weatherproof hub. The hub has very low rolling resistance and features silky smooth shifting so you’re ready to tackle anything on the commute.

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.

Gates Carbon Belt Drive

Clean living

The Gates belt drive is the ultimate commuter drive system: it’s clean, light, quiet, and requires zero maintenance.
Clean
Unlike chain drive systems, the Gates belt drive doesn’t require any grease. It’s always dry and clean—an extra bonus when you’re riding with your nice pants or squeezing onto a crowded subway.
Light
The Gates belt, rear sprocket, and front sprocket together weigh less than just the chain it replaces.
Low Noise
The Gates belt runs silently—always—unlike a chain that needs regular lubrication to run quietly.
Zero Maintenance
The Gates belt does not stretch (unlike a chain) and will last twice as long. It won’t rust and never needs lubrication—a big plus if you ride in wet, icy weather and roads get salted in the winter.

Cargo Kickstand

Ready to Haul

The Cargo Kickstand is built strong and will keep your fully loaded Tern bike upright. It uses Pletscher’s rear chainstay mount design.

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.

Cargo Rack™

Load ’er up

The Cargo Rack is designed to get stuff off your back and onto your bike so you can enjoy the ride. It is outrageously stiff and chock full of smart details that make it better than anything else we’ve used for hauling large loads. Optimized for the unique geometry of Tern bicycles.
Outrageously Stiff
A rack with inadequate stiffness has a very disorienting fishtail effect when carrying a heavy load. For stiffness, we use super-oversized tubular aluminum for the top deck and a DoubleTruss™ rear stay design that triangulates the rear stays.
Pannier Compatible
The Cargo Rack is height adjustable so that it will fit pannier bags and baskets of all sizes. It’s designed so panniers sit a little further back on the rack, ensuring adequate heel clearance on every compatible Tern bicycle.
KlickFix Compatible
The Cargo Rack is compatible with all KlickFix Rackpack compatible baskets and trunk bags on the top deck.
SideStrap™ Bungee System
Anybody who’s had something on the rear rack slip off and into a rear wheel knows how important it is to have a steadfast rear strap system. The simple but versatile SideStrap™ system is brilliant at keeping loads of all shapes and sizes firmly in place so you can ride with confidence.
Adjustable
Fully adjustable upper and lower stays allow you keep the rack low and sleek when you’re in town and up high when you’re touring with full-sized panniers.
