 The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. With an electric drivetrain, 20” wheel bikes are just as fast as 700c. That means riders can enjoy all the benefits of small wheels—compact size, low center of gravity, quick acceleration, maneuverable handling, and plenty of cargo space—with big wheel speed.

The Vektron Q9 is equipped with hydraulic disc brakes, a sturdy rear rack, Valo Direct light, and fenders—so it is ideal for all-season commuting in the city.

  • German-engineered Bosch Active Line electric drivetrain—the industry leader in electric bike technology
  • Hydraulic disc brakes for all-weather stopping power
  • New frame design, with a reclining battery for a lower center of gravity and better ride
  • Integrated Atlas Rack works seamlessly with Thule Yepp Maxi and Nexxt Maxi child seats—no adapters needed
  • Resizes in seconds to fit riders 147 – 195 cm (4’10” – 6’5”) so a single bike can be shared by the family




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.

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.

With structural cues from the heavy-duty Tern GSD, the new Atlas Rack has been massively strengthened and increased in size. 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.

Adapted from Bosch’s German-engineered automotive applications, the Active Drive Line drive unit can take you up to 25 kmh 15.5 mph 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.
