The Tern Vektron is a groundbreaking bike that takes cues from cargo bikes, electric bikes and folding bikes. 

How can it do so much? Well, it might be because Tern fancies themselves a transportation company, not just a bike company.  When you're trying to solve transportation problems, you approach design problems from a solution oriented perspective, rather than trying to fit your product into a category within the bike industry. 

All that means that the Tern is a truly innovative, well thought out, super strong bike that can climb steep hills, cover great distances, carry 1 kid and then fold up and fit under your desk at work. Security is a serious concern for quality electric bike owners - folding bikes have a unique advantage in this regard in that you can bypass the whole locking-your-bike-up-in-public thing.


  • It’s electric! You might miss the sweetest part of this bike what for all it's cool features. This is an honest to goodness folding electric bike that feels great, folds small and even looks cool in a futuristic kindof way. We are smitten.

  • This is a family bike, believe it or not! Rear rack will accept 1 Yepp seat with an optional adapter. Rides great!

  • Includes fenders, lights and kickstand. Following in line with the general trend in quality ebikes, the Tern Vektron comes with all the accessories you need, shy of a quality lock.

  • NEW! Features Bosch Active Line Plus. The newest motor system from Bosch, the Active Line Plus shaves weight from other Bosch systems while retaining a powerful 50Nm torque.

  • Wait, do I even need a lock with this bike? Probably so, but by it's very folding nature, this bike can join you in your office, in your car, on the train, on the bus, in the restaurant, and maybe, awkwardly, in your shopping cart.

  • Looks like a folding bike, doesn't ride like one. In the same way Xtracycle seems to have nailed Longtail geometry, Tern absolutely crushes folding bike handling with the Tern Vektron. In other words, this thing rides great.

  • Crazy patented adjustable stem thing. Tern loves gadgets and cool parts. Thankfully, they also care about safety. Their super-strong, super-adjustable quick release stem allows you to customize the fit of this bike on the fly, or easily share it with another rider of a different size.


Tern warranties their frames for 5 years against defects in material and/or workmanship. Warranty is non-transferrable. Bicycle components (excluding tires, chain, cables, etc.) generally have a 1 year limited warranty. Bosch electric components carry a 2 year warranty.
