CRUSH YOUR COMMUTE

The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. With an electric drivetrain, 20” wheel bikes are just as fast as 700c. That means riders can enjoy all the benefits of small wheels—compact size, low center of gravity, quick acceleration, maneuverable handling, and plenty of cargo space—with big wheel speed.

The Vektron D7i comes equipped with a Nexus 7 drivetrain. With all the gearing on the inside, your bike is simple and tidy. Paired with Shimano hydraulic brakes, a heavy-duty Tern Cargo Rack and full fenders, the Vektron D7i is up for all occasions.

  • Bafang M400 Drive System - 250 watts of responsive and dependable power
  • 7-speed internal geared Shimano hub for versatility and low maintenance
  • Hydraulic disc brakes for all-weather stopping power
  • Tern Valo Direct light, with 150 lumens of power, for 24 hour visibility
  • 400 Wh battery for a range of up to 90 km
  • Andros stem, to fit riders from 160 – 195 cm in seconds
  • Tern Loader Rack G2 for hauling your gear

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.

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.

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.

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.

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.

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.

ALL-WEATHER STOPPING POWER


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

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.

POWER TO THE PEOPLE


The M400 System adds smooth and quiet power to your natural pedal-stroke, helping you ride faster and farther. Since you're riding farther, and getting there quicker, more destinations feel a 'bikable' distance away. That means you'll ride more often too. The M400 System is optimized for range and torque, giving you faster acceleration and five levels of power-assistance to overcome hills and headwinds when you need to, or save power for later.

RAW POWER


The M400 System Battery gives you enough juice for up to 90 km of power-assisted riding. It offers 400Wh of charge, supplied by the same Panasonic batteries chosen by Tesla. It locks on the bike, and comes off with you for theft protection and indoor charging.

THE CONTROL CENTER


The M400 System Display is the nerve-center of your electric bike. Cycle through six power modes, run your lights, and even get the bike to walk itself at the push (and press) of a button.

FOR A FASTER FOLD


The Centerstand Kickstand does everything a standard center-mount kickstand can do, plus it helps you fold your Vektron with ease. Simply extend the Centerstand and the Vektron balances on its rear wheel. Fold the frame, stem and handlepost, all without lifting your bike.

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.

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.

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.

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.

A REAR RACK THAT'S READY TO CARRY


Built from 6061 lightweight aluminum and with a triangular design for strengthened support, the Loader Rack carries loads up to 25 kg (55 lb) without a hassle. This KLICKfix™ compatible rear rack supports compatible bags and baskets, and its lower side tubes ensure your loaded side panniers always stay in place.
