Product Reviews

The manufacturer [of the Vektron P7i] stands for perfection with a highly stable frame construction and well-secured but easy-to-open folding hinges.

Auto Zeitung

The Tern Vektron (2021) combines a serious folding commuter bike and the more powerful Bosch Performance Line (Gen 3) drive system to create a bike that customers have been asking for: a folding electric bike with ample power and a ride quality that defies logic.

The New Wheel

Rear rack and panniers increase the Tern Vektron's suitability for everyday use. It also shines with impeccable riding characteristics.

EBike

The Tern Vektron is suitable for taking children and transporting groceries. Folded, it is as big as a long-distance suitcase and can be taken on the ICE train.
