When Tern introduced the GSD Gen 1 in 2017, it redefined what cargo bikes could be. Compact, versatile, and capable of carrying heavy loads in urban environments, it essentially launched the compact cargo bike category. Now, in 2025, the Tern GSD Gen 3 raises the bar once again—offering greater load capacity, improved ride comfort, smarter tech, and more customisation than ever before.
At elctrc, we’re excited to be receiving the new GSD models from June to September, including the GSD P10, S10, and R14. Whether you’re a parent, delivery rider, or just looking for a car replacement, this is the cargo e-bike that does it all—only better.
Despite its impressive load capacity, the GSD Gen 3 maintains a footprint similar to a standard bike. It features:
FlatFold™ folding handlebars and stem, making it easier to load into vehicles or store indoors.
Vertical Parking mode—stand it on its rear rack to minimise floor space use.
Vertical Rolling allows easy movement through tight spaces like elevators or hallways.
The GSD Gen 3 has been re-engineered for strength:
Max Gross Vehicle Weight (MGVW): 210 kg (463 lb)—best in class.
Rider weight capacity: 130 kg (287 lb).
Rear rack rated for 100 kg, capable of carrying two children or even an adult.
Integrated TowBar and optional Tail Hitch L for towing trailers or even other bikes.
The GSD Gen 3 is your modern family vehicle:
Carries passengers, could be 2 child seats, 2 older children or even an adult.
New Rain Fly, Sun Shield and Mud Shield accessories offer full-weather protection, launching along side the bike, more info soon.
Loads passenger add-ons and set ups like Clubhouse, Captains Chair, Joyride Bars, Stow Decks, and Seat Belts.
No two riders are the same—and the GSD Gen 3 reflects that:
Compatible with all Gen 2 accessories.
Modular rear and front rack systems.
Stow Decks for extra support, fold away completely for storage.
Options for delivery bags, dog carriers, grocery panniers, or cargo boxes.
Lower centre of gravity and longer wheelbase improve handling, especially when loaded.
Tuned geometry for confident cornering and smoother starts.
Suspension fork for comfort and control on bumpy roads.
Standard on S10 and R14, the new Bosch Smart System gives you:
Kiox 300 display with full ride data and smartphone connectivity.
eBike Lock – disables the motor when you remove the display.
eBike Alarm and GPS tracking (with Flow+ subscription).
Dual battery compatibility for extended range on bigger days out.
Ignis 700-lumen headlight with high/low beam options.
RearStop Brake Light™ that activates automatically when braking.
Magura 4-piston hydraulic disc brakes for consistent stopping power.
Always-on lights wired to the Bosch power system.
Available on R14, the belt is low maintenance, silent, grease-free and ideal for year-round use.
Tern supports its riders like no other brand:
10-year warranty on frame, fork, and handlepost (with Tern Care registration).
7-year availability promise on batteries and key components.
Tern Warranty Transfer allows remaining warranty to pass to new owner.
Supported by the Bosch global service network.
And as a Bosch-certified Tern dealer, elctrc ensures that your GSD arrives fully built, tuned, and backed by local expert support in Brighton and Sussex.
