Tern GSD S10 Bosch Cargo Electric Bike - Gloss Tabasco/ Dark Grey

Carries Your Family
Our ecosystem of passenger-carrying accessories fits your family—now, and five years from now. Carry two little ones in child seats and watch as they grow into (and out of) the Clubhouse. Give your spouse a lift on date night with the Captain’s Chair. Snap a photo of the day your teen graduates to carrying you.

Cargo-Ready
The GSD is made to fit your life, including all your stuff. Our ecosystem of accessories includes a wide range of cargo-carrying gear 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.

Year-Round Riding
Keeping your kids dry and cozy is the key to happier rides and fewer complaints. The Clubhouse Fort transforms the Tern GSD into an all-weather solution to carry young passengers all year round.

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, we’ve made it easier for the rider’s feet to reach the ground at stops.

Easy to Transport
We think the GSD will help you leave your car behind more often than not. Still, there are times when using a car and a GSD together is the best solution. The GSD packs down to one third of its volume in seconds. Stick a GSD (or two!) in the back of a minivan or small SUV, no heavy-duty rack required.

Small-Space Friendly
A regular bike takes up a lot of floor space and can be hard to store in a small living space (never mind getting it in and out of the elevator). We solved this problem by designing the GSD to park vertically, so it takes up about as much space as a potted plant—perfect for city apartments and elevators.

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.
