2025 Tern GSD R14 Gen3 800Wh/1600Wh Electric Cargo Bike With Belt Drive & ABS In Iron Grey & Dark Grey

The new GSD takes the family electric cargo bike to a whole ‘nother level.

Smarter than ever and packing even more muscle with a re-engineered frame that handles a max gross vehicle weight of 210kg (463 lb), it’ll help you carry 2 loved ones and weekly grocery hauls with newfound ease – but it’s similar in length to a regular bike to remain surprisingly manageable.

This cargo bike comes with an 800Wh battery and is able to accept an optional second 800Wh battery to take the total capacity to an amazing 1600Wh, giving you miles and miles of seemingly endless range if riding light or using a low amount of pedal assist. With two batteries installed you could enjoy a surprising number of typical urban journeys (such as school runs or shopping trips) over many days or weeks on a single charge, depending on load weight and assistance levels. 1600Wh gives you a range of up to 179 miles, so if you were travelling 5 miles per day then potentially a single charge could last a whole month! It's not easy to beat that level of energy cost efficiency and convenience.

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 swap places to carry you.

It is made to fit your life, including all your stuff, and the range of accessories includes a wide selection 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.

The bike'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, Tern have made it easier for the rider's feet to reach the ground at stops.

The Greener, Leaner Family Minivan

A more efficient alternative to the family minivan that’ll let you breeze past traffic jams and ditch the gas pump, the GSD comfortably carries up to 2 kids—from toddlers to teens—making school runs and shuffling from one activity to the next stress-free. It’ll even take an adult passenger, so you can keep the fun times rolling when it’s just you and your +1.

Fits Your Needs

Choose from our wide range of modular accessories for passengers, pets, and cargo to transform the GSD into your ideal vehicle for tackling big and small tasks. Whether it’s safely transporting kids in all sorts of weather, hauling gear to your next gig, or grabbing the obligatory pizza & 12 pack for game night, the GSD is made to fit your life and everything that comes with it.

Carries Even More

Built on a stronger, stiffer hydroformed frame with optimized geometry to handle its biggest payload capacity yet, the beefed up GSD proves that you can haul, well, just about anything with the right bike and a little ingenuity—especially when you’ve got a best-in-class max gross vehicle weight of 210 kg (463 lb) at your disposal.

Rides Even Better

With a longer wheelbase and an all-new frame that brings the center of gravity even lower to the ground, the GSD offers next-level stability to complement its huge cargo capacity. Add to the mix a fine-tuned geometry for easier handling under heavier loads, and you’ve got a cargo bike you can confidently ride, no matter what you’re hauling.

Vertical Parking

The safest place for your bike is indoors, away from bad weather and thieves. But when every inch counts in the city, that’s not always an option. The GSD makes it easy by parking vertically, reducing its footprint to the size of a potted plant so it fits neatly in a small corner of your home or office.

Vertical Rolling

The GSD flips upright to roll vertically, letting you easily push it down narrow hallways and into tight spaces like elevators. Perfect for apartment living and shared spaces, vertical rolling offers a simple, effective solution for getting your cargo bike to its storage spot.

Flat-Folding

Want to bring a cargo bike on your next trip? The GSD’s patented Physis Handlepost™ folds down in seconds without tools to turn the bike into a flat package that transports easily in the back of an SUV or on a train, ready to get the good times rolling wherever your journey takes you.

Committed to Your Safety

The GSD passed rigorous stress testing by EFBE Prüftechnik GmbH, with forces scaled up to ensure the frame and fork can reliably handle its 210kg (463 lb) weight rating as specified in the German DIN 79010 cargo bike safety standard. Plus, its entire Bosch® eBike system—including the motor, battery, and charger—is certified to UL 2849 to ensure fire safety.

Brakes Under Control

Leveraging advanced ABS tech from cars and motorcycles, Bosch eBike ABS stops the wheels from locking up during emergency braking or slippery conditions, preventing skidding and maintaining traction. This enables faster, smoother braking with better control to help you steer clear of obstacles for a safer, more comfortable ride.

One Size Fits Most

With a Tern-custom seatpost to support larger builds and comfort tuning to fit even the very petite, the GSD effortlessly accommodates riders 150 - 200 cm (4'11" - 6'7") tall with a max weight of 130 kg (287 lb). Its adjustable cockpit resizes in seconds with the flip of just a few levers to help riders find their best fit, making it super simple to share amongst family members.
