The Tern Vektron P5i is a high quality folding e-bike that can carry a lot of stuff, and folds simply and reliably into a small enough package that it’ll easily fit on a train luggage rack or into the boot of a car. It rides well, and fits a good range of rider sizes from ... Read more

This high-end folding e-bike offers comfort, responsive pedal assist, and a compact, user-friendly design. In my experience, many folding e-bikes are directed at consumers who may be new to riding or uncertain of how often they plan to use their purchase. As such, I’ve noticed that many manufacturers of folding e-bikes make highly affordable, entry-level
The Vektron P5i rides just like a “regular” bike, thanks to its smooth, responsive, and capable Bosch Performance Line mid-drive motor.
Tern designed the bike for awesome portability, with a frame that folds small, can stand upright, and can roll easily when folded.
The P5i model is quiet, clean, and remarkably low-maintenance, with a Gates Carbon belt and Shimano Nexus internal gear hub.
It has quick steering and nimble handling due to its relatively low weight and 20” wheels.
The single frame size fits riders from 4’10” to 6’5”, thanks to its dual-telescoping seatpost and adjustable Andros stem.
It’s advanced, yet easy to use. The Bosch system feels precise without adding the complexity of too many settings or an app.
The Vektron is equipped from front to back with premium components, ensuring reliability, great performance, and serviceability.
Tern offers up to a 10-year warranty on its frames, forks, and handleposts—be sure to sign up for Tern Care to maximize your coverage!
It’s compatible with a wide range of accessories, including cargo baskets and luggage, storage and transport bags, etc.
We liked the ability to quickly switch off the headlight, but we hoped to see functioning brake lights on such an urban-friendly e-bike.
Vektron models in the US aren’t compatible with Bosch’s highly useful Flow app. We’d love to see that functionality in the future.
