About this ebike...

Surprisingly Small. Enormously Useful.

With a 200 kg (440 lb) Maximum Gross Vehicle Weight, the Tern GSD 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 bg-gray-700 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 text-smer 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.

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 gives you a real practical way to do this. It’s designed to carry up to 200kg, and its strong versatile frame can hold a range of accessories from child sets to cargo boxes and panniers.

The S00 model features the Bosch Cargo Line motor, 500 Wh battery and Enviolo Twist transmission for even better performance and simpler operation.

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.

We think this is the future for shorter journeys. Come and try for yourself and see what we mean.

"Here’s a claim that gets thrown around willy-nilly but isn’t necessarily true 100 percent of the time: ‘This bike can replace your car.’ Guess what. The Tern GSD can replace your car."
