Maximum cargo capability, minimum compromise — the Tern GSD S10 is built to replace a car, not just assist your ride. The Tern GSD S10 is a compact longtail cargo e-bike designed for serious everyday utility, combining massive carrying capacity with surprisingly nimble handling. Powered by the Bosch Cargo Line Smart System motor, it delivers up to 85Nm of torque and strong, natural-feeling assistance that makes heavy loads and steep hills feel manageable. Despite its strength, the GSD is engineered to remain compact in length, making it easier to store than many traditional cargo bikes while still offering exceptional stability on the road. Built around a reinforced frame rated for heavy-duty use, the GSD S10 supports a total system weight of up to 200–210kg depending on configuration. Its low centre of gravity, 20-inch wheels, and purpose-built cargo geometry keep handling predictable even when fully loaded with children, groceries, or work gear. A highly adjustable cockpit allows riders of different heights to share the bike comfortably, while integrated accessories and a wide ecosystem of cargo add-ons make it one of the most adaptable family and utility bikes available.
