All the power and performance of a Bosch e-bike in a portable package. In product test after product test, the Vektron is called the best folding e-bike on the market. The new Vektron gets even better with improved geometry, Bosch’s newest and virtually silent motor, and a burly, extended rack. Get a Vektron and a lot of your car trips will start turning into bike trips.

Ready to Roll - Once you fold your Vektron, it’s easy to roll it around. The new frame design also lets you keep the bike in vertical position when folded, so stopping and going is easier than ever.

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.

Takes You Further - Take your Vektron on a train or bus to cover those extra-long commutes, or to complete the first and last leg of your commute faster. Ride to the station, hop on, hop off, and keep riding.

One Size Fits All - The Vektron has a low-step frame design and resizes in seconds—no tools required—to fit riders between 145 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family.

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.

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.

Shimano Alivio Shadow derailleur

Geared for the city

For most cities, the resilient 9-speed Alivio Shadow derailleur is all you really need—with the added benefit of keeping everything tucked away for extra protection, which comes in handy when you need to transport your folded bike.

Bosch Active Line Plus

Carefree riding

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.

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 Dash® RM 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.
