Product Description

The Tern Vektron is a mean looking utility bike that has various functional and practical features as well as high performance components to make every commute and errand a breeze.

The S10 400 uses a 400W battery with a little more power storage whereas the S10 300 has a more economical 300W battery.

With a compact 20″ wheel and 2-point folding frameset, it will drop to 1/3 its original size to fit into elevators, on trains and buses, under your desk or in the boot of your car whilst retaining comfortable, efficient and nimble feel when assembled.

The seamless power-assist integration gives a considerable boost to your pedal stroke, getting you to those meetings extra early with plenty of time to whip up a brew. The battery will assist the bike for +30 miles on a single charge, and even if you choose not to use it there’s a 1×10 Shimano Deore drivetrain with plenty of gear range. Another useful feature is the battery powered lights for 24 hour visibility.

The high volume city tyres combined with hydraulic disc brakes provide ultimate control on the tarmac and the 20″ diameter allows agile filtering and negotiating, because who wants to be stuck behind 3 taxis and a bus on a beast like this?

TECHNOLOGY

OCL+™ FRAME JOINT
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.

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.

PORTER+™ SADDLE
CARRY YOUR BIKE COMFORTABLY

We reengineered the underside of the age-old bike saddle into a comfortable grip and shoulder pad. 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™ on the underside of the saddle lets you grip the saddle nose with comfortable confidence when your rolling your folded bike.

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.

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 POWERPACK BATTERY
FEATHER-LIGHT POWERHOUSE

This impressive high-energy, high-power cell clips on and off your bike. The best-in-class design charges fast and lets you ride longer and further between charges. You’ll be impressed by its long lifespan, light weight, and ease of charging. Select from 300, 400 and 500 Wh variants and forget about range anxiety.

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.

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.
