Brand 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.

Perfect Portability..

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

Brakes & Gears

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!

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.

Magura's MT4 brakes are an incredibly strong set of anchors and fit perfectly and the stop and go urban riding style.

10 speed gearing in the form of the Shimano Deore 11-36t group set is well balanced for city riding and light off road use.

Deore trigger shifters are quick, smooth and reliable, making this the perfect commuter bike.

Wheels & Tyres

The Tern Vektron S10 is grips with decent Schwalbe Big Apple tyres which are designed for maximum grip whilst keeping rolling resistance to a low. More importantly they include kevlar lining protection to prevent annoying punctures.

The S10 comes equipped with Schwalbe Big Apple 20"x2.1" tyres. An excellent all purpose option, being a 20" wheeled bike there is a huge crossover with other styles of bike and so future tyre options are vast. More importantly they include the kevlar lining protection to help prevent annoying punctures.

The bottom line..

Although compact, the wheel base is that of a regular bicycle, the handlebar, fork and overall geometry give for a nice smooth and comfortable ride whilst maintaining the practicalities of being able to pack this cargo bike away.

Tern have developed a fully built in LED lighting system front and rear. Completely powered off the Bosch system there is no need to carry bulbs, batteries, and they cant be easily stolen and reused.

The new Tern Vektron electric folding bike ticks the boxes for those looking for a nice ride and neat solution to travel and storage. A nice simple, but good quality electric bike, suitable for a mixture of riding styles and rider heights.

I purchased this bike to use with my motorhome

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.
