Vektron S10

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.

Magura MT4 Hydraulic Disc Brakes

FULL STOP

Hydraulic disc brakes give you excellent stopping power, working effortlessly even in rain, snow, or mud. All it takes is the gentle pull of just two fingers. With mineral oil-based brake fluid that is gentler on the environment than most hydraulic brake fluids, and Magura's Easy Bleed Technology, your Vektron is ready for a safer ride.

Bosch Performance Drive Unit

Power Trip

Electric bikes make it easy to ride from A to B. Where it gets interesting? When you’re inspired to visit the rest of the alphabet. The Bosch Performance Drive Unit offers a fine-tuned balance between torque and range. It takes the burden out of hauling kids and groceries. With up to 100 km of range with a standard 400 Wh battery, it’s the market leader in ebike technology.

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 V Rack

AN ULTRA-ROBUST RACK WITH GSDna

With structural cues from the heavy-duty Tern GSD, the new Atlas V 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 V 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.
