2026 Tern GSD Gen3 Range Explained
Tern GSD S10, P10, P00 and R14 - Which Model is Right for You?
For more nearly a decade the Tern GSD has been one of the defining compact cargo eBikes for families and businesses. Built to carry up to 210 kg of combined weight, take two children or an adult passenger, and still fit into lifts, sheds and bike stores that larger cargo bikes cannot, the GSD has become a practical car replacement for dense cities like London.
For 2026, Tern has introduced the GSD Gen3 platform. The line-up now features four distinct models - R14, S10, P00 and P10 - each mapped to different budgets, drivetrain characteristics and duty cycles. Common features include Bosch’s latest Smart System, dual-battery capability, UL and DIN safety certification, and a deep accessory ecosystem for both family and fleet use.
The 2026 Line-up
Tern GSD S10 — Versatile Family Workhorse
- Price: £5,900
- Bosch System: Smart System Cargo Line
- Drivetrain: Shimano Deore 1×10 chain
- ABS: Yes
- Battery: 545 Wh (up to 1090 Wh)
- Ideal for: School runs, errands, adventures & weekend family use
The S10 balances price, performance and usability. ABS brings additional stopping confidence in poor weather or when heavy loads. Shimano’s 10-speed drivetrain offers broad and serviceable gearing, while optional dual batteries allow for extended rides or commercial work. For many buyers, the S10 represents a rational entry into the GSD platform.
Tern GSD P00 — Smooth, Silent & Family-Friendly

The P00 combines Enviolo’s stepless gear hub with a Gates belt for an exceptionally smooth and low-maintenance experience. Shifting at standstill, silent operation and no chain oil are attractive for households with children and small storage spaces. While it does not feature ABS, the P00 offers a more relaxed and fuss-free ride character suited to everyday family life.

Paired with a belt drive and ABS, it delivers confidence on wet roads, hills and tight corners with children or cargo on board. Dual 800 Wh batteries make the R14 suitable for riders replacing significant car mileage or fleets seeking predictable servicing and long-term reliability.

What’s New in GSD Gen3?
Bosch Smart System
All GSD models now run Bosch’s latest Smart System, enabling navigation, ride stats, tuning and over-the-air updates via the Bosch Flow app. eBike Lock comes as standard, with optional GPS tracking and alarm functionality when paired with the ConnectModule.
Dual-Battery Capability
All models support dual-battery bays, with total capacity varying by model. This supports longer school runs, multiple errands in a day, or commercial riders covering significant mileage.
Load & Fit
The GSD retains its 210 kg maximum system weight and 100 kg rear rack rating, alongside an adjustable cockpit that fits riders from 150–200 cm without tools. It parks vertically and remains one of the few high-load cargo bikes designed to integrate into constrained urban storage.
Safety Standards
The Gen3 platform is third-party tested to the German DIN 79010 cargo bike structural standard, and UL 2849 for electrical safety across the Bosch system. ABS is available on the R14 and S10 models.
Security, Tracking & Insurance
Security has become a key consideration in major UK cities. Bosch’s Smart System enables eBike Lock as standard and supports optional GPS tracking and alarm functionality with the ConnectModule. For higher-risk areas, pairing the GSD with a high-quality lock, secure storage and specialist eBike insurance can meaningfully reduce financial risk and downtime for both families and fleets.
Ways to Buy
The GSD Gen3 range can be purchased outright or via a number of salary, tax and fleet mechanisms:
- Cycle to Work (including GCI, Cyclescheme and salary sacrifice providers)
- Finance and instalment options
- Outright
- Fleet purchase and invoicing for commercial operators
- VAT recovery for eligible businesses
- Insurance and extended coverage options
For many families, Cycle to Work significantly improves affordability. For businesses, VAT recovery and fleet purchasing can reduce total cost of ownership compared to cars, mopeds or vans.
The Fully Charged Verdict
The Tern GSD Gen3 range broadens the appeal of an already proven platform. With four drivetrain and battery tiers, dual-battery capability, Smart System integration and meaningful safety certification, there is now a GSD for most scenarios. Families will likely settle on the P00 or S10, while commercial fleets may lean toward the S10, P10 or R14 depending on duty cycle and service intervals.
