Why We Love the Tern GSD S10

The Tern GSD S10 has been a cornerstone of our electric cargo bike range for good reason—it just works. Whether you're climbing Wellington's steepest streets, dropping the kids to school, or hauling groceries in the rain, the GSD handles it all with confidence.

It’s one of the most popular electric cargo bikes for families looking to replace their car, thanks to its compact footprint and serious hauling power. Powered by the Bosch Cargo Line motor with up to 85 Nm of torque, the GSD can conquer hills fully loaded with ease. The option to upgrade to a dual battery setup gives you all-day range—perfect for those living further out of town or running errands back to back.

The GSD fits a wide range of rider heights (150–195 cm), making it genuinely shareable between partners. Its sturdy double kickstand and low rear deck make loading kids or cargo a breeze. It’s also one of the few cargo bikes that can be stored upright, a game changer if you're tight on space.

Tern’s extensive range of modular accessories means you can build your perfect setup—child seats, weather covers, panniers, passenger cushions and more. Whether you’re transporting two young kids or loading up for a weekend adventure, the GSD adapts as your life changes.

It’s built with durable, serviceable parts—Shimano drivetrain, Magura hydraulic brakes, and a solid rear rack system—making it a long-term investment you can rely on. We've serviced hundreds of these bikes over the years, and they’ve proven themselves over and over again in Wellington's tough conditions.
