Conquer hills and headwind—without breaking a sweat
All around the world, the way we get from A to B is changing. With the world on the verge of auto-mobility, driverless cars, ride-sharing, and the mainstream arrival of electric vehicles, it’s an exciting moment for transportation. To help drive this force of change, Tern developed a small collection of electric bikes that take hills, headwinds, traffic, and bike thieves out of commuting.
The Vektron Q9 is equipped with hydraulic disc brakes, a sturdy rear rack, Valo Direct light, and fenders—so it is ideal for all-season commuting in the city.

Updated Vektron Frame
RE-ENGINEERED FOR A BETTER RIDE
With a re-worked frame and frame geometry, the updated Vektron is now even better. The cockpit is longer for improved comfort for taller riders. The frame has been designed with additional forged and machined elements for additional strength without extra weight. The battery now reclines backwards, keeping the center of gravity as low as possible for superior handling. And the new design allows the Vektron to stand up vertically when folded, making it even easier to roll around.
Bosch Active Line
Adapted from Bosch’s German-engineered automotive applications, the Active Drive Line drive unit can take you up to 25 km per hour (20 mph in the U.S.) and operates dependably—day in and day out. The new generation of the Active Line is also 28% lighter and 25% smaller than the previous one, maintaining its excellent performance and low-levels of vibration while delivering an even quieter ride with less pedal resistance.
Bosch PowerPack Battery
This impressive high-energy, high-power cell clips on and off your bike. The best-in-class design charges fast—from zero—in only 2.5 to 3.5 hours, and lets you ride longer and further between charges. You’ll be impressed by its long lifespan, light weight, and ease of charging. PowerPacks are available in 300/400/500 Wh variants, so you can forget about range anxiety..
LONGER SEATPOST. SMALLER FOLD.
This seatpost is perfect for tall riders or anyone who likes a compact fold. It extends 90 mm longer than our stock seatpost, but thanks to its unique design, it’s 120 mm shorter when retracted. It features a dual-bolt head design for precise saddle adjustment, and an inner post diameter of 27.2 mm, so you can customize it with other posts.
Shimano Alivio Shadow Derailleur
GEARED FOR THE CITY
For most cities, the resilient 9-speed Alivio Shadow derailleur is all you really need—with the added benefit of keeping everything tucked away for extra protection, which comes in handy when you need to transport your folded bike.
Keep it together
The Magnetix 2.0 uses powerful magnets to keep your bike folded for situations like carrying your bike up and down stairs. With a pull force 10-15 Kgf, the Magnetix 2.0 will keep your bike folded even when being jostled and moved about.
Carry more stuff
Fix the Tern Luggage Truss to the Luggage Socket and you can plug in your choice of front luggage: rack, basket, or bag. If it’s KlickFix compatible, it’ll work.
