Airstream x Tern Vektron S10 Overview
The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. Shorten distances and flatten the hills on your commute, or put a couple of Vektrons in the trailer for your next roadtrip, so you can explore further.
Folds Up for Easy Storage: One of the biggest benefits of the Tern Vektron is that it folds down quickly and easily. This means you can store it in small spaces in your Airstream or unfolded on a Fiamma rack.
Electric Boost for Easier Rides: The Vektron has an electric motor that helps you pedal, so riding is easier and less tiring, especially on hills or longer. It makes getting around while camping much more enjoyable without breaking a sweat.
Comfortable and Adjustable: The bike is designed to fit a wide range of riders, thanks to its adjustable handlebars and seat post. Whether you’re tall or short, you can find a comfortable riding position. Plus, the ride is smooth and stable, even at higher speeds.
Carries Your Stuff: Despite being a folding bike, the Vektron is strong and can carry your essentials, like a backpack, groceries, or even a small child on the back. It’s practical for everyday use during RV season.
Low Maintenance: The Tern Vektron is built with quality components that are durable and require less maintenance, so you spend more time riding and less time worrying about repairs.
Fun and Convenient: Lastly, riding the Vektron is simply fun! The electric boost makes it feel like you have superpowers when you’re cycling, and its portability means you can take it with you almost anywhere.

Geometry
The Vektron is built in a single universal frame size with an adjustable cockpit rather than multiple frame sizes. Tern does not publish a stack/reach/tube-angle geometry chart for this model — folded dimensions and rider height range above are the published fit data. Note: Tern's global spec sheet lists a 25 km/h (EU) max-assist speed; the Bosch Purion unit specified for US-market bikes is governed to 20 mph (28 km/h) per Class 1 e-bike regulations — flagging this regional spec variance for transparency.
