Our patented Andros Stem, Physis 3D Handlepost, and OCL+ Frame Joint are incredibly strong and stiff, easy-to-use, and serviceable.

250 Watts of Dependable Power

The Bosch-equipped Vektron can take you up to 25km/h (20 mph in the U.S.), maintaining its excellent performance while delivering a quiet ride with less pedal resistance.

No More Range Anxiety

With a Bosch PowerPack, your Vektron gets a range of up to 130 km. Clip your battery on and lock it for theft protection, or clip it off for easy indoor charging.

Night-time Safety

The Vektron comes equipped with integrated lights front and rear so you can see and be seen. The lights are wired to your Bosch battery so you’ll never have to charge your lights again. Up front the Vektron features the upgraded Valo Direct light with 30% more light output.

All-Weather Stopping Power

With hydraulic disc brakes, your Vektron is ready for a safer ride, giving you excellent stopping power, and working effortlessly even in rain, snow, or mud. All it takes is the gentle pull of just two fingers.

Strong and Stiff Rack

With a burly frame-integrated rack that carries up to 27 kg, the Vektron handles well even when loaded. The Atlas V Rack is KLICKfix-compatible, and was designed to work seamlessly with a Thule Yepp Maxi or Nexxt Maxi child seat.
