Vektron Q9

Technology

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.

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

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.

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.

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.

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—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. PowerPacks are available in 300/400/500 Wh variants, so you can 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.

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, with a load capacity of 27 kg (59 lb). 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.

Product Reviews

Fairkehr

The Tern Vektron is suitable for taking children and transporting groceries. Folded, it is as big as a long-distance suitcase and can be taken on the ICE train.

Electrek

It rides like a dream and unlike just about any folding bike I’ve ever tried.
