Vektron P9

Technology

OCL+™ Frame Joint

Robust folding technology

A heavy-duty update to our iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.

Andros™ Stem

Adjust to fit

The Andros is our patented adjustable stem that lets you set your handlebars where you want—no tools, no fuss. In just seconds, you can set your riding position to long and low in a tough headwind, or upright and comfy for riding around town. You decide how you want to ride and the Andros makes your bike fit.

Shimano Hydraulic Disc Brakes

All-weather stopping power

Shimano hydraulic disc brakes deliver powerful stopping power in all weather conditions with the touch of a finger.

Schwalbe Big Apple Tires

Cush for your tush

Big Apples are special because they’re fast rolling AND super comfy. Sounds hard to believe but you’ll just have to take them for a ride to become a believer.

Bafang M400 Drive System

Power to the People

The M400 System adds smooth and quiet power to your natural pedal-stroke, helping you ride faster and farther. Since you’re riding farther, and getting there quicker, more destinations feel a ‘bikable’ distance away. That means you’ll ride more often too. The M400 System is optimized for range and torque, giving you faster acceleration and five levels of power-assistance to overcome hills and headwinds when you need to, or save power for later.

Bafang M400 Drive System Battery

Raw Power

The M400 System Battery gives you enough juice for up to 90 km of power-assisted riding. It offers 400Wh of charge, supplied by the same Panasonic batteries chosen by Tesla. It locks on the bike, and comes off with you for theft protection and indoor charging.

Bafang M400 Drive System Display

The Control Center

The M400 System Display is the nerve-center of your electric bike. Cycle through six power modes, run your lights, and even get the bike to walk itself at the push (and press) of a button.

Valo™ Direct Light

Immediate illumination

Our 41 lux, 150 lumen Valo Direct lights up your ride without adding the drag or weight of a dynamo. It’s engineered to sit inside the handlebar stem, where it’s safe from knocks, bumps, and theft. That means it’s protected while folding, and optimally positioned to give you the most light.

Product Reviews

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.

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.
