Discover the Vektron: A best-in-class folding e-bike with Bosch power. Folds in 10 seconds, perfect for trains, commuting or the camper van.

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.

The Vektron stands out in the electric bike market as a premium folding e-bike that combines performance, practicality and versatility. Consistently rated as best-in-class, this innovative bicycle folds in just 10 seconds, making it ideal for multi-modal transport and storage in compact spaces.

At its heart is the reliable Bosch eBike System. The Bosch PowerPack battery provides impressive range capabilities of up to 130 kilometres, eliminating range anxiety for longer journeys. The battery can be easily locked to the frame for security or removed for convenient indoor charging.

The bike’s thoughtful design includes a frame-integrated Atlas V Rack that can carry up to 27 kg of cargo and is compatible with various accessories, including Thule Yepp Maxi and Dash RM child seats. Safety features include integrated front and rear lights powered by the main battery, with the upgraded Valo Direct front light offering 30% more brightness. The hydraulic disc brakes ensure reliable stopping power in all weather conditions.

Adaptability is a key strength of the Vektron, with its low-step frame design accommodating riders from 147 to 195 cm (4’10” to 6’5”) through tool-free adjustments. When folded, the bike maintains a vertical position for easy rolling and transport.

Built for longevity, the Vektron features Tern’s patented technologies including the Andros Stem, Physis 3D Handlepost, and OCL+ Frame Joint, all designed for durability and serviceability. The bike meets strict European safety standards (EN 15194-compliant) and features UL-2849 certification for its electrical systems. This commitment to quality is backed by a comprehensive 10-year warranty.
