Tern Vektron

$3,400.00

The Tern Vektron takes everything great about folding bikes—multi-modal commuting, portability for travel and storage—and accelerates it. All around the world, the way we get from A to B is changing. With the world on the cusp of auto-mobility, ride sharing, and the mainstream arrival of electric vehicles, it’s an exciting moment for transportation. To help drive this force of change, we developed the world’s most compact Bosch-driven electric bike.

The Tern Vektron is a Bosch powered folding ebike that made for riders that don’t want compromises in ride quality or comfort. It’s the Folding Electric Bike we have been waiting for!

Tern Vektron 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.

Tern Vektron 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 Vektron 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 Vektron 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.

Tern Vektron 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.

Tern Vektron 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.

Tern Vektron Porter+™ Saddle
ROLL WITH CONTROL
We reengineered the underside of the age-old bike saddle into a comfortable grip for transporting your folded bike. Up top, the dual-density construction and gel cushioning will keep you comfortable on the road, and the impeccably finished vacuum construction makes the saddle waterproof and easy to clean. Down below, the GripPad™ lets you roll your folded bike with comfortable confidence.

Tern Vektron Shimano Deore Hydraulic Disc Brakes
STOP ON DEMAND
Leveraging technology that’s been working successfully on motorcycles for decades, these brakes will bring you to a confident stop—even in rain, snow, or mud. All it takes is the gentle pull of just two fingers. The caliper design is both ridged and durable, and the non-corrosive mineral oil brake fluid is gentler on the environment than most hydraulic brake fluids.

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.

Tern Vektron 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.

Tern Vektron 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.

Tern Vektron 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.

Tern Vektron 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.

Tern Vektron 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.

Bosch PowerPack Battery

Feather-light powerhouse: This impressive high-energy, high-power cell carries 300 watt-hours (Wh) of power in the EU, and 400 Wh in the U.S. The best-in-class design charges fast—from zero—in only 2.5 to 3.5 hours, and lets you ride longer and further between charges. You’ll be impressed by its long lifespan, light weight, and ease of charging.

Fast Charging: High-power density allows the PowerPack to charge to 50% in just 1.5 hours and fully in just 2.5 – 3.5 hours.

More Mileage: Ride nice and long between charges thanks to best-in-class energy density.

Light Weight: At just 5.5 lb, the weight is practically negligible during riding. The PowerPack is an ingenious balance of performance, size, and weight.

Long Lifespan: PowerPacks are designed for many tours, miles, and years of service. The integrated Battery Management System protects the battery from overcharging, undervoltage, overheating, and short circuiting.

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 Active Drive Unit
UNIVERSAL PERFORMANCE
Adapted from Bosch’s German-engineered automotive applications, the Active 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. Its high-performance electronics, whisper-quiet operation, and low-levels of vibration are remarkable—especially given the lightweight, ergonomic design.

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.
