Who is this bike suitable for?

Why compromise on class and quality with a folding electric bike? Combining versatility, portability and efficiency, the Tern Vektron S10 is the perfect bike for those who want to enjoy cycling, whilst still being able to go the distance on all manners of terrains, courtesy of Bosch.

With folded dimensions of just 41x86x61cm, the Tern Vektron can be tucked under your desk, the pub bench or on the boat, making it the perfect electric bike for commuting or weekend outings. Running late for the train? No worries - the Vektron S10 can be folded down in 10 seconds! The lightweight alloy frame makes this a foldable electric bike that can be carried up a flight of stairs, making this bike a portable transport option for those living in high rise environments.

The Tern Vektron makes hopping between your favourite city spots a delight; allowing you to get where you need to go, with more energy to enjoy the things you love, once you reach your destination.

Why Buy Tern? Why Fully Charged?

With the world on the verge of auto-mobility, driverless cars and ride-sharing, and with the arrival of electric vehicles, it is Tern’s ambition to help drive this force of change with a collection of electric bikes that take hills, headwinds, traffic and bike thieves out of commuting. As an urban mobility business that focuses specifically on the compact eCargo and folding sector, Tern’s range of bikes give an unrelenting focus on ride quality and are ideal for commuting and storage purposes. Whether you have children to take on the school run, goods that need transporting or if you’re loading up your bike for a weekend adventure, look no further than Tern.

We have formed a close relationship with Tern and were awarded best Tern global dealer of the year in 2021. The Tern range features some of the best selling eBikes across our stores, with several of our staff personally owning Tern bikes and using them everyday!
