Description

The Tern GSD S10 is a compact electric longtail cargo bike built around a single, practical idea: replace the car for everyday errands, school runs, and deliveries. The 6061 aluminium frame uses Tern's patented MultiTruss design and carries DIN 79010 certification, meaning it is rated for a total system weight of 210 kg. Despite that capacity, the GSD S10 is shorter than most longtails, making it easy to navigate traffic and store.

Power comes from the Bosch Cargo Line motor — 85 Nm of torque with up to 400% pedal assistance. In practice, this means the bike feels responsive even when the rear rack is fully loaded. The Bosch PowerPack 545 Wh battery detaches quickly via the Fast Swap system, and a second battery slot is available if you want to extend your range with an optional second pack. Ride settings and navigation are handled via the Bosch Kiox 300 display and LED Remote, with the Bosch eBike Flow app for your phone.

Stopping safely when fully loaded is handled by Magura MT-C hydraulic disc brakes with 4-piston calipers and 203 mm rotors front and rear. Bosch eBike ABS is integrated, automatically preventing wheel lock in emergency braking situations — a meaningful safety feature when carrying children or heavy cargo. Ride comfort is supported by a Suntour custom Tern fork (34 mm stanchions, thru-axle) and a Cane Creek suspension seatpost.

The GSD S10 ships fully equipped: Ignis 700-lumen front light, RearStop brake light, Schwalbe Pick-Up Super Defense tyres, and a Shimano Deore 1x10 drivetrain with an 11-42T cassette for a wide, usable gear range. Available in Satin Beige & Dark Grey.

Bosch PowerPack 545 Wh

Practicality above all. The Bosch PowerPack 545 Wh is the benchmark external battery for cyclists who prioritize ease of use. Mounted directly on the frame tube, it can be removed in one move for charging at home or in the office — without having to move the bike. With 545 Wh of capacity, it largely covers everyday needs and medium-distance outings. Positioned near the bike's center of gravity, it guarantees natural and balanced driving behavior, without weighing down the steering or unbalancing the mount. Fully compatible with the Bosch Smart System, it benefits from all the intelligence of the Bosch ecosystem for optimal energy management.

Bosch Kiox 300

Information, without compromise. The Bosch Kiox 300 is the connected screen that strikes the right balance between readability, compactness and functionality. Mounted on the handlebars, it displays all the essential data of your ride on a clear and readable backlit screen - even in direct sunlight - without cluttering the cockpit. Connected to the eBike Flow app via Bluetooth, it provides access to software updates, personalization of riding modes and detailed monitoring of your performance. Easy to use, it is aimed at both urban cyclists and demanding hikers who want to keep an eye on their data without complicating their lives.
