This is the new Gen 2 Vektron S 10
All around the world, the way we get from A to B is changing. With the world on the cusp of auto-mobility, ride sharing, and the mainstream arrival of electric vehicles, it’s an exciting moment for transportation. To help drive this force of change, we developed the world’s most compact Bosch-driven electric bike. The Tern Vektron takes everything great about folding bikes—multi-modal commuting, portability for travel and storage—and accelerates it.

Adapted from Bosch’s German-engineered automotive applications, the Active 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. Its high-performance electronics, whisper-quiet operation, and low-levels of vibration are remarkable—especially given the lightweight, ergonomic design.
