Ride it, Fold it, Go Further

The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. Shorten distances and flatten the hills on your commute, or put a couple of Vektrons in the trunk of your car on your next trip, so you can explore further.

Rides Better

There are other folding electric bikes but none ride better. The Vektron is stiff and stable for a truly solid ride—even when fully loaded. Take a test ride and feel the difference.

Kiddie Compatible

School runs have never been more fun! The frame-integrated Atlas V Rack™ is designed to fit a Thule Yepp Maxi or a Dash® RM seat—no adapters needed.

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

Haul all your gear with ease. 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 Dash® RM child seat.

OCL+™ Frame Joint

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

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.

Bosch Active Line Plus

With a little more torque for smoother acceleration, the Bosch Active Line Plus 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 Plus is also 20% 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.
