The folding e-bike that doesn't compromise. The Tern Vektron folds in 10 seconds, carries 27kg on its rack, and rides like a proper bike – not a toy.

The Tern Vektron is the folding e-bike for people who refuse to compromise. It folds in 10 seconds for trains, cars, or under desks – but it rides like a proper bike. With Bosch power, 27kg cargo capacity, and room for a child seat, this isn’t a novelty folder. It’s genuine transport that happens to fold.

Who is this bike for?

The Vektron is perfect if you:

  • Mix cycling with public transport – Folds in 10 seconds for trains, buses, or the tube
  • Need to store a bike in limited space – Fits under desks, in cupboards, or small flats

The folder that rides like a bike

Most folding bikes make compromises – the Vektron doesn’t. It has the motor, battery, and components you’d expect from a full-size e-bike, packaged into something that fits in a train luggage rack. If you’ve dismissed folders as toys, this one demands reconsideration.

Customer reviews

★★★★★Sheila WattsSeptember 2025

After thinking about buying an electric bike for a few weeks I arranged a test drive with Jack for a Saturday morning. his service and knowledge was excellent. He was patient with my questions and gave me as much time as I needed. I bought the bike I’d gone there to try and have no hesitation in recommending Jack/E-Radicals.

★★★★★Ben ThomasMarch 2025

I can’t thank Jack enough for his level of expertise in helping me purchase an e-bike. He really went above and beyond in promptly sourcing a bike from Tern, and hand delivered the bike to me. I highly recommend Jack and E-Radicals, a great business and a thoroughly nice chap!
