Product Reviews

The New Wheel

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.

Fairkehr

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.

Frankfurter Allgemeine

"[The Vektron Q9] is more pedelec in every respect, absolutely suitable for touring, even with a child seat or panniers, and at the same time comfortable and smooth despite its weight."
