Meet the Vektron: Our Ultimate Folding Electric Bike
Exceptional Ride
With a rigid frame and handlepost that minimize flex, dialed-in geometry, and best-in-class Bosch drivetrain, the Vektron delivers exceptional ride quality that’s hard to match among folding bikes—confident, stable, and effortlessly smooth. Meanwhile, those seeking a quieter, cleaner ride with less upkeep will appreciate the belt drive and internal gear hub options.
Folds in a Flash
Designed for urban dwellers and multimodal travelers, the Vektron quickly folds down into a compact, space-saving package that’s easy to transport and store. Just a few lever flips and it’s ready to go on the metro, ride in the car boot, or fit into a hallway nook.
Roll with It
Why carry when you can roll? Thanks to a user-centric design, the folded Vektron rolls easily through train stations, elevators, and in & out of your favorite cafe—bike in one hand, iced coffee in the other.
Comfort That Fits
The Vektron’s cockpit includes an adjustable stem for your ideal riding position, a telescopic seatpost to fit a wider range of rider heights, swept-back handlebars, and wide ergonomic grips. It resizes in seconds without tools to fit riders from 147 to 195 cm (4’10” to 6’5”), so everyone gets a ride that always feels just right.
Accessorize Your Ride
The Atlas V Rear Rack features a double-rail design that lets you attach baskets, panniers, and bags to both the top and sides. It’s compatible with KLICKfix, Racktime SNAPIT 2.0, and Ortlieb Quick-Lock 2.1 and 2.2 systems, giving you plenty of setup options. Plus, a hidden Luggage Socket allows for front-mounted accessories.
Tested for Safety
Third-party tested for EN 15194 compliance, the Vektron meets strict requirements for e-bike safety, performance, and design. Its Bosch eBike system—including the motor, battery, and charger—is certified to UL 2849, ensuring electrical and fire safety to give you total peace of mind whether you’re riding or charging indoors.
Why the Vektron
Patented Folding Tech
The custom-engineered Andros Stem, Physis 3D Handlepost, and OCL+ Frame Joint are incredibly strong and stiff, easy-to-use, and serviceable.
Bosch Smart System
Stay connected and ride smarter with an advanced e-bike system that offers app control, custom riding modes, added theft protection, and everyday convenience.
eBike Lock
Once activated in the Flow app, eBike Lock disables motor support each time you switch off your e-bike to help prevent theft—then reactivates automatically via Bluetooth when you return.
OCL+ Frame Joint
Our heavy-duty OCL+ Frame Joint is engineered to exceed ISO 4210 and EN 15194 testing requirements. Thanks to a single-shaft design, advanced welding techniques, robust gussets, and four igus bearings between the moving parts, folding stays smooth, stiff, and secure ride after ride.
Schwalbe Big Apple Tires
These balloon tires feature a wider construction and built-in suspension that soak up bumps and rough roads, delivering a smooth, cushioned ride with low rolling resistance. Built-in puncture protection ensures you go about your day without interruptions.
Gates Belt Drive
Exceptionally silent and smooth, the Gates Carbon Drive belt easily outlasts several chains and requires little to no upkeep, staying reliable even through road salt and grit. No grease, no rust. Just hose it down and keep riding, with a clean fold every time.
