Physis™ 3D Handlepost
The new benchmark
Five patented technologies and unique manufacturing technology add up to the strongest, stiffest folding handlepost available. The Physis uses a special manufacturing process called 3D forging, which forms the post from a single piece of aluminum, eliminating all welds.
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.
Bosch Active Line Plus
With a little more torque for smoother acceleration, the Bosch Active Line Plus 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 Plus is also 20% 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.
Bosch Purion Control Panel
COMPACT CONTROL CENTER
The on-board computer lets you switch between five different riding modes, and feeds you handy information like speed, battery level, and distance. It optimizes shifting actions and constantly updates you on the remaining range, just like a typical German car. Best of all, it’s now more compact and robust than ever.
Atlas V Rack™
AN ULTRA-ROBUST RACK WITH GSDna
With structural cues from the heavy-duty Tern GSD, the new Atlas V Rack™ has been massively strengthened and increased in size, with a load capacity of 27 kg (59 lb). This reduces flex for more secure handling when the bike is loaded. Riding with your little one? Add a Thule Yepp Maxi or Dash® RM child seat—no adapters needed. The Atlas V Rack™ is also KLICKfix-compatible, and can hold panniers of different sizes—including the Bucketload Pannier, which was designed to fit every configuration of the Vektron.
The e-folding bike Tern Vektron is the permanent test winner among folding bikes. Rides like a big bike, but you can take it on the train for free—or in the car trunk.
Of all the e-folders featured here, the Vektron Q9 is the one that brings the most full-size e-bike qualities to the table. It is the only one with a mid-drive, in this case courtesy of Bosch, making it the most powerful e-folder here.

While it weighs less than 50 pounds and folds up to roughly the size of a skinny end table in seconds, the Tern Vektron Q9 is versatile enough to carry riders up to 6 feet 3 inches with everything you need to get to work.
The pedelec from Tern rides well to very well on all surfaces, even without suspension, the voluminous tires dampen pleasantly.
By configuring the Vektron Q9 with a mid-drive motor, Tern’s designers have optimised weight distribution, giving this folding e-bike fantastically balanced agility.
Conclusion: With the Vektron, Tern has developed a great folding bike for those looking for a compact and practical bike for everyday use.
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.
Having tested the Vektron lineup before, we can say these bikes are the real deal, and designed for e-bike riders who are seeking the highest level of manufacturing and reliability.
