Tern GSD

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.

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.

Rock-Solid

Loading heavy cargo or kids on and off a bike can be tricky business, so we created the Atlas Lockstand. It’s an unbelievably strong and stable kickstand that automatically locks into place when engaged. When you’re ready to go, just press the Remote Unlock lever and roll forward.

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.

Bosch Cargo Line Motor

A powerful motor that’s cut out for heavy loads and hilly roads. Natural-feeling e-assist with up to 85 Nm of torque and 400% support.

Stronger, Stiffer Frame

The GSD has always been super strong, but we’ve made it even beefier for a better ride. The added stiffness prevents side-to-side motion, even when heavily loaded.

Atlas Wheels

The GSD’s wheels may be small, but they’re strong enough to carry big. Custom-designed to withstand the 200 kg max gross vehicle weight of the GSD.

Combo Mount

Attach front racks and more using the robust Combo Mount. Since it’s located on the frame itself (and not the fork), you can load it up without sacrificing proper steering.

Dedicated Trailer Mount

Easy to use, very secure, and optimized to prevent trailer tilt. Compatible with Thule, Burley, and Weber trailers, no adapters needed.

Integrated Lower Decks

The rugged Integrated Lower Decks offer built-in support for cargo and passengers’ feet. Got a truly oversized load? Add the Sidekick Wide Decks for extra room and even more load capacity.

Easy-Step Frame Design

Updated frame geometry makes the GSD comfier for riders of all sizes. A slacker seat tube angle and higher handlebars create a better-fitting cockpit and a more upright riding position. Plus, it’s now easier for riders’ feet to reach the ground at stops.

Custom Suspension Fork

We built a special suspension fork to add comfort and control while safely handling the GSD’s massive 200 kg MGVW.

Suspension Seatpost

Cane Creek Thudbuster suspension seatpost for an extra-cushy ride. Tool-free elastomer adjustment makes it easy for riders of different sizes to share the bike. Equipped on GSDs with the LX package.

Ignis Headlight

Riding home after dark or in bad weather? No worries. The 700-lumen front light provides extra visibility with a brighter light and a wider beam. A one-touch high/low beam puts even more light at your fingertips. Equipped on GSDs with the LX package.

RearStop Brake Light

Let drivers know to give you space when you’re stopping or slowing down. Always on, day or night, with enhanced side visibility.

Full Chainguard

The chainguard helps you stay tidy (no pant-rolling required) and prevents long skirts and loose pants from getting caught in the chain or belt.
