A closer look at the Vektron Q9

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.

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.
Fits the Family
Accommodates riders of all sizes so one bike can be shared by multiple riders.
Forged Construction
The patented design is FEA optimized and fully forged for maximum strength with minimum weight.
Built to Last
Stainless hardware and brass bushings for long-term durability.

Velo Ergonomic LockOn Grips

Be kind to your hands

ErgoLock grips are nice and wide for excellent palm support so your hands can relax during the ride. They also lock in place on the handlebars so they’re always in the correct position, unlike non-locking grips which tend to rotate out of position.

Porter™ Saddle

A new way to carry your bike

One of our favorite ways to get a Tern bike up a set of stairs is to hook the nose of the saddle over a shoulder. It’s fast and easy, but the nose of the saddle can be hard. We solved this pain-point by re-engineering the underside of the saddle into a comfortable shoulder pad. It cushions and “grips” your shoulder so your hands are free to carry other things—like a backpack or the weekend’s groceries.

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.

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.

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 Alivio Shadow Derailleur

GEARED FOR THE CITY

For most cities, the resilient 9-speed Alivio Shadow derailleur is all you really need—with the added benefit of keeping everything tucked away for extra protection, which comes in handy when you need to transport your folded bike.

Bosch Active Line

UNIVERSAL PERFORMANCE

Adapted from Bosch’s German-engineered automotive applications, the Active Drive Line drive unit can take you up to 25 km per hour (20 mph in the U.S.) and operates dependably—day in and day out. The new generation of the Active Line is also 28% lighter and 25% smaller than the previous one, maintaining its excellent performance and low-levels of vibration while delivering an even quieter ride with less pedal resistance.

Ergonomic
The ergonomically designed handle makes it easy to insert and remove the PowerPack for charging. Charge it easily on or off the bike.

Bosch Purion Control Panel

Compact control center

The on-board computer lets you switch between five different riding modes, and feeds you handy information like speed, battery level, and distance. It optimizes shifting actions and constantly updates you on the remaining range, just like a typical German car. Best of all, it’s now more compact and robust than ever.

Magnetix™ 2.0

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.

Herrmans H-Flow

LIGHT THE WAY

Powered by an electricity-generating hub, this 82-lumen, 40-lux light illuminates the road ahead with a powerful 19-meter-long beam that’s wide enough to give you side-of-the-road visibility. A cooling system ensures the LED light stays bright until you reach your destination, and it’s weatherproof and splash-proof. So, bring on the puddles.

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. 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.
