Who is this bike for?

Store the Vektron easily at work, home or in the back of the car. The strong frame, carbon fork and Schwalbe Big Apple tyres means once the Vektron is unfolded, it rides extremely smoothly on tarmac or on light off road tracks.

Tern's mission to protect the planet and simplify people's lives is epitomized by the Vektron. It's durable frame, fast folding mechanism and Bosch system make it a real life hack for the city!

Vektron Performance

The Vektron is one of the first folding eBikes to successfully integrate the Bosch system, making this bike the highest performing portable electric bike we have seen!

The Vektron has a unique take on the frame for a folding eBike, although the wheel base is compact, the geometry of the frame makes for a comfortable ride while not compromising on the practicalities of stowing the electric bike away.

Bosch Portability

The new Vektron folding eBike uses Bosch's latest Active Line system, featuring a 300 PowerPack with the option to upgrade to a 400 Powerpack.

The system is designed to measure the cadence, radiance and speed of the riders pedalling to deliver a very elastic power curve, making for an incredibly smooth ride!


Whether you want to fold the bike for the train, stow it away under your desk at work or pack it away in a car or a plane, this Vektron folds up quickly and easily. The patented folding mechanism allows you to naturally fold as you release the catches, meaning it only takes around 10 seconds!


An angled adjustable seat post accommodating for riders between 4ft 8 and 6ft 5 and high spec components makes the Vektron a fantastic all round eBike that is great for a mixture of uses.

Active Line

There are 4 power modes to choose from - Eco, Tour, Sport and Turbo, and of course you can always turn it off and ride it like a normal bike! In Turbo mode the motor packs a punch, offering 225% assistance and 48Nm of torque, making getting up hills super easy!
