Tern GSD G2 Animation Scenario - Propel E-Bikes

Still Small. Even More Useful.

With a 210 kg (463 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

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.

One Size Fits Most

The GSD has an adjustable cockpit that resizes in seconds and without tools to fit riders 150 – 200 cm tall (4’11” – 6’7”), 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.

Year-Round Riding

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

Tern GSD G2 Loading - Propel Electric Bikes

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.

Tern GSD G2 Vertical Parking - Propel Electric Bikes

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.

Built to Last

Our philosophy is to keep our bikes on the road for as long as possible, not to create disposable products that are built to fail. We start with intentional design choices that make the bike serviceable and safe—and end up with a reliable vehicle you can use day in, day out. Then, we back it up with great local service and a 10-year warranty for peace of mind.

Tough and Tested

EFBE Prüftechnik GmbH, one of Europe’s leading bicycle testing labs, put the GSD through its paces to prove the frame and fork can handle the 200 kg (440 lb) mass gross vehicle weight ride after ride.

UL Tested and Certified

The GSD’s Bosch motor system and battery are UL-2849 certified. They’ve been carefully tested for safety against potential hazards.

Built and Assembled by Experts

Your GSD is carefully built by certified Tern Dealers who will run through a thorough pre-delivery safety checklist before handing over your new bike.
