Tern GSD S10 LR

About this ebike...

Still Small. Even More Useful.

With a 200 kg (440 lb) Maximum Gross Vehicle Weight, the Tern GSD S10 LR is ready to replace your car. It’ll let you carry two kids plus groceries, or a whole lot of cargo—but it’s the same length as a regular bike. Built-in dual-battery technology lets you ride all day, while space-saving features like FlatFold and Vertical Parking make the GSD incredibly easy to own and use.

One Size Fits Most

The GSD has an adjustable cockpit that resizes in seconds and without tools to fit riders 150 – 195 cm tall (4’11” – 6’5”), so you can easily share it with your family. The updated frame geometry with a slacker seat tube angle and higher handlebars also means the GSD doesn’t just fit—it’s more comfortable too.


The GSD is made to fit your life, including all your stuff. Tern’s ecosystem of accessories includes a wide range of cargo-carrying designed to keep your loads secure and stable for wobble-free hauling. You may not have thought of using a bike to pick up groceries, home improvement supplies, or plants for your garden—but now you will.

Easy to Manage

The GSD’s unique geometry makes for super stable riding, no matter what you’re hauling (or how wiggly your kids are). The low center of gravity lets even smaller riders confidently manage heavy loads, and the step-thru frame makes getting on and off the bike a breeze. Plus, Tern have made it easier for the rider’s feet to reach the ground at stops.

The Bosch Advantage

All GSD models now feature the best-in-class Bosch Cargo Line motor, which provides up to 85 Nm of torque for a smooth, natural-feeling ride, and 400% support to tackle serious hills. Top it off with Bosch’s unparalleled service and expertise, and you can rest assured that your GSD’s motor system will be safe and reliable for years to come.

Is this the right ebike for me?

If you are looking to ditch the car, increase your fitness, reduce your costs, carry kids and/or cargo, have fun, reduce pollution, save the planet or maybe all of these, then the Tern GSD S10 LR gives you a real practical way to do this. It’s designed to carry (load and rider) up to 200kg, and its strong versatile frame can hold a range of accessories from child sets to cargo boxes and panniers.

It’s also easy and great fun to ride, and with its dual battery option the range is huge – we guesstimate up to 125 miles. Storing it is made as easy as possible, it’s the same length as a regular bike, believe it or not, and the handlebar stem folds down to reduce its height if you want to load it into a car or other space.

"The Tern’s big selling point is that for all its cargo capacity and versatility, it’s actually no longer than a standard big-wheeled bike."
