Still Getting Sh!t Done
The new GSD takes the family electric cargo bike to a whole ‘nother level. Smarter than ever and packing even more muscle to replace your car with a re-engineered frame that handles a max gross vehicle weight of 210 kg (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.
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 is a true car replacement & 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
Turning your GSD into a family car replacement is easy when you 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 a true car replacement 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.
space-saving e-bike design
vertical parking
The safest place for you 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 to store your e-bike inside 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.
committed to your family's e-biking safety
For your family's safety, we engineered and built the Tern GSD cargo e-bike extra strong. It surpassed rigorous stress testing by EFBE Prüftechnik GmbH, with forces scaled up to ensure the frame and fork can reliably handle its 210 kg (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 Anti-Lock Braking System brake safety technology from cars and motorcycles, Bosch eBike ABS stops the wheels of the Tern GSD from locking up during emergency braking or in wet, slippery conditions, preventing skidding and maintaining traction & control. This enables more reliable, faster, and smoother braking with better control to help you steer clear of obstacles for a safer, more comfortable ride.
* Available on GSD R14 & S10
One Size Fits Most
With a Tern-custom seatpost to support larger builds and comfort tuning to fit even the very petite, the Tern GSD's flexible fit system effortlessly accommodates both short and tall riders ranging from 150 - 200 cm (4'11" - 6'7") in height with a max weight of 130 kg (287 lbs). 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.
Stronger, Stiffer Frame
Precisely crafted from advanced hydroforming tech for superior strength, rigidity, and durability, the all-new GSD frame handles larger loads with confidence-inspiring stability, thanks to an optimized geometry for carrying heavy cargo.
Robust Rear Rack
Strong and stiff with best-in-class load capacity of 100 kg (220 lb), the Atlas G Rack can carry supersized shopping hauls or passengers big and small. Easy to maintain, its durable powder-coated finish is scratch-resistant to keep it looking like new.
Versatile Support
A patent-pending innovation from Tern, the Stow Decks™ lock securely into place at 5 different angles—supporting partially or fully-loaded panniers, bulky cargo, or your passengers’ feet, and neatly folding away when not in use.
Frame-Integrated TowBar
The GSD's burly TowBar™ lets you easily link a passenger, cargo, or pet trailer directly to your bike. Add theTail Hitch L to shift the trailer further back and make room for loaded panniers, or combine it with our Bike Tow Kit to bring along an extra bike.

It Has All You Need

Full-Coverage Wheel Guard
An integrated rear wheel guard keeps passengers away from the spinning wheel, and your precious cargo safe from mud, slush, and dirt. Add the MudShield™ fender extension for maximum coverage when riding in heavy snow or rain.
It’s Designed for Safety
Dependable Kickstand
Custom for the GSD, the patented Atlas Lockstand has features you’ll love: built-in extensions for a wider stance and maximum stability, remote unlocking, and a protector that prevents mud and debris from gunking up the kickstand lock.
Always-On Brake Light
Standing by, day or night. The RearStop Brake Light™ activates when you press on the brakes to slow down or stop, alerting other road users to give you space and steer clear. It’s wired directly to the power supply, so you never have to worry about charging.
Ultra-Bright Headlight
Low light or bad weather? The 700-lumen Ignis Headlight™ casts a strong light and wide beam so you can see clearly ahead, and be seen by others. On GSD R14 and S10 models, a one-touch Hi/Lo beam readily puts even more light at your fingertips.
Powerful 4-Piston Disc Brakes
A bike that can carry this much calls for some serious stopping ability. That’s why we chose Magura® quad piston hydraulic disc brakes for maximum braking power, so you can safely and confidently bring a heavily loaded GSD to a halt, rain or shine.
It’s Extra Comfy
Smooth Suspension Fork
Rigorously tested to withstand stress under maximum load, the GSD’s suspension fork damps the harshness of potholes and uneven roads to greatly enhance your riding comfort. By reducing the impact felt through the handlebars, it also helps you maintain better control and stability—especially when carrying heavy loads.
Adjustable Stem
An integral part of the GSD’s adjust-to-fit cockpit, the patented Andros Stem™ lets you dial in your preferred handlebar height and angle in seconds without the need for tools, creating a comfy riding position whether you’re tall or small.
Shock-Absorbing Seatpost
The GSD comes with a custom seatpost for solid support, but for an even cushier experience, the GSD R14 and S10 are equipped with legendary suspension from Cane Creek® to absorb shocks, smooth out bumps, and minimize vibrations, allowing you to enjoy longer rides without strain.
