    [The Tern Vektron P9 only shows one bigger weakness - and that is the motor support in stop-and-go mode, typical for urban traffic. Testers also criticized the portability when folded. The range of almost 62 kilometers also allows extended trips. The motor works with a smooth response.]


    “Nous voilà séduits par les performances du moteur central Bafang Max Drive.
    Sur le plan du pilotage le Vektron p9 procure beaucoup de Plaisir. Son coté compact lui permet de se faufiler aisément dans le flot de la circulation tout en restant bien stable grace à un centre de gravité bas. Quant à la position de pilotage, elle est confortable et ne procure pas la moindre tension musculaire.“
