Who is this bike suitable for?

The new 2022 Tern Vektron S10 folding bike has an almost infinite number of uses. Whether riding to work and having the versatility to fold the bike on or off a train, getting to work and tucking away under a desk or all round leisure riding, the new Vektron S10 can do it all. The Schwalbe Big Apple tyres fitted as standard are suitable for both on tarmac and light forest tracks, bridle ways & canal tow paths. The folded dimensions are just 41x86x61cm, meaning it can even fit into the boot of a small hatchback!

Most electric bicycles on the market are heavy & difficult to carry around. But the Vektron from Tern and Bosch is a new kind of e-bike: light, compact, and able to fold up small enough to fit in a car trunk. - inhabitat

New Features

The new Tern Vektron S10 could be the most versatile Bosch eBike on the market. Looking for portability and an efficient German assisted eBike? The Tern Vektron S10 does just that.

For 2022, the Vektron S10 gets an upgrade to the Bosch Performance Line motor, giving it a useful power boost with an extra 15Nm of torque over previous models.

The Vektron S10 offers a unique approach to frame design. With a telescopic seat post and adjustable angle stem, it can accommodate riders from 4ft 10 to 6ft 5. Few other bikes allow for such a vast range of rider type. 

Although compact, the wheel base is that of a regular bicycle and the handlebar, fork and overall geometry provide a smooth and comfortable ride comparable with an ordinary bike while maintaining the practicalities of being able to fold this electric bike away. 

2022 Tern Vektron S10 Folding Electric Bike

With an impressive specification list, the Vektron S10 is prepared for anything!

Tern is well known for their long history of reputable and reliable folding bikes. Now, with the addition of a Bosch drive system, they bring a unique approach to the modern rider. 

Folding the 2022 Tern Vektron S10 Electric Bike


Whether under the desk at work, getting it on and off the train or stowed away in the back of your car or motor home, the Tern Vektron S10 is our most versatile and portable folding electric bike.

In 3 simple steps - The handlebars fold down, the frame folds in half and the seat can be retracted to fit this electric bike into even the smallest of places with ease.

The Tern folds from a complete bike down to folded format in under 10 seconds. This is due to the patented folding mechanism, which naturally folds as you release the catches.

No magic involved, just excellent design!

Notice how little space it takes up with wise. This is because of it's excellent folding and that the off side pedal removes, shortening overall width further.

Load Carrying

Recently re-designed, The Tern Vektron now shares the same rear rack design of its big brother the Tern GSD folding cargo bike. The rack now has improved strength over previous Vektron models, eliminating flex for better handling when fully loaded.

This design allows for the Bosch PowerPack 400Wh Battery to be mounted under the rack offering a longer platform whilst also lowering the centre of gravity for better stability.

The additional space means that the Tern Vektron can be fitted with a child seat from the "Clubhouse" range and is also fully compatible with Thules Yepp Maxi or Nexxt Maxi child seats.

This, combined with Klickfix compatibility makes the Vektron equally at home on the school run, work commute or even the food shop.

Much like the GSD, the rack also doubles as a storage option, allowing for the bike to be stood up on its end when folded to further lessen the bikes footprint when not in use.

User Friendly.


The Tern Vektron S10 offers all of the rider essentials you would expect of an ordinary bike, including a comfort gel saddle, adjustable handlebars, comfort grips and adjustable seat post.

On top of this, the Vektron comes fully equipped with mudguards, pannier rack and side stand.

Tern have developed a fully built in LED lighting system front and rear. Completely powered by the Bosch system itself, there are no bulbs or batteries to change and they cant be plucked off by a a passing opportunist!

As is now standard on Tern folding electric bikes,  Magura hydraulic disc brakes front and rear offer a user friendly, low maintenance experience whilst having enough stopping power to bring you and your cargo to a halt quickly!

The front chain ring and chain is covered by Tern's unique chain guard, keeping you, the rider, clean in all conditions. As both the Bosch motor and battery are mounted in the centre of the bike, it makes for an even weight distribution between the wheels whilst keeping the centre of gravity low, for a nimble and responsive ride. 

Shimano Gears on Tern S10 2022 Folding Electric Bike

Gearing on the Tern is provided by Shimano's Deore 10 speed drive train, for simple shifting both up and down hill.

Operated using a dual action trigger shifter on the handlebars, the Shadow+ rear rear derailleur keeps the chain taught even over bumpier terrain. 

The alloy double wall rims offer a strong and lightweight solution for smaller 20" wheels. Laced onto Shimano quick release hubs, wheel removal for punctures and maintenance is exactly the same as a non-electric bike.

The Tern Vektron is grips the road with Schwalbe Big Apple tyres which are designed for maximum grip whilst keeping rolling resistance to a minimum.  More importantly they include the Schwalbe K-Guard kevlar lining protection to prevent annoying punctures.

The Big Apple's are also designed to absorb the riding surface, giving a more comfortable overall feel for the rider. 

Bosch Performance Line on Tern S10 Folding eBike

Bosch Performance Line System

Customer Reviews

Great bike a little heavy but rides well recently had a stroke and the pedal assist is brilliant
I purchased this bike to use with my motorhome. I was unsure about being able to use it as I am 19 stone, 69 years old and suffer with long covid. After a few practice rides I got the hang of it. It became very easy and effortless to ride without becoming breathless. I feel like I have been rejuvenated.
