The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. With an electric drivetrain, 20” wheel bikes are just as fast as 700c. That means riders can enjoy all the benefits of small wheels—compact size, low center of gravity, quick acceleration, maneuverable handling, and plenty of cargo space—with big wheel speed.
The Vektron P9 comes equipped with a nine-speed Sora drivetrain, for all the gearing you need in the city. With the Tern Cargo Rack, Valo Direct light, and full front and rear fenders, it’s purpose-built for all-season commuting.

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.
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.
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
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.
Valo™ Direct Light
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.
