Tern GSD S10 LR Longtail cargo bike

With a 200 kg (440 lb) Maximum Gross Vehicle Weight, the 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.

Carries Your Family

Tern's 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.

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.

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.

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.
