Tern GSD Gen3 2026: S10 vs P10 vs P00 vs R14 Comparison | Fully Charged
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
- Price: £6,500
- Bosch System: Smart System Cargo Line
- Drivetrain: Enviolo Heavy Duty hub + Gates belt
- ABS: No
- Battery: 545 Wh (up to 1090 Wh)
- Ideal for: School runs, errands, adventures & weekend family use
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.
Tern GSD R14 — Premium, Minimal-Maintenance & Fleet-Grade
- Price: £8,900
- Bosch System: Smart System Cargo Line
- Drivetrain: Rohloff E14 hub + Gates belt
- ABS: Yes

- Ideal for: High performance, minimal maintenance & long-term family vehicle solution.
The Rohloff E14 drivetrain enables electronic shifting and extremely low wear under load. 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.
Tern GSD P10 — The Accessible GSD
- Price: £4,900
- Bosch System: Bosch System 2, Cargo Line
- Drivetrain: Shimano Deore 1×10 chain
- ABS: No
- Battery: 500 Wh (up to 1000 Wh)
- Ideal for: Entry-level purchase, school runs, errands, weekend trips.
The P10 brings the full GSD platform - including Cargo Line motor, 210 kg system capacity and dual-battery capability - to a more accessible price point. The simpler configuration appeals to commercial fleets managing cost structures, and to families seeking a more affordable route into the GSD world without compromising hauling capability.
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.
Tern GSD Gen3 FAQs (2026)
What is the cheapest Tern GSD Gen3?
The cheapest GSD Gen3 is the P10 at £4,900, which comes with a Bosch Cargo Line motor and a 500 Wh battery. It uses a traditional Shimano drivetrain and skips features like ABS and belt drive to keep costs down, while still offering the full 210 kg load rating. It’s the most accessible way into the GSD platform for families and small businesses.
Does the Tern GSD Gen3 have ABS?
Yes, ABS is available on the S10 and R14 models only. The P00 and P10 do not include ABS. Bosch eBike ABS helps prevent wheel lock-up in emergency braking and slippery conditions, improving control when riding with children or heavy cargo.
What is the Tern GSD maximum weight capacity?
All GSD Gen3 models support up to 210 kg combined system weight (bike, rider, passengers, cargo, and accessories). This rating is verified through DIN 79010 cargo bike testing and reflects real-world family and commercial use, not just theoretical limits.
Which Tern GSD models have a belt drive?
The P00 (Enviolo + Gates belt) and R14 (Rohloff E14 + Gates belt) use belt drives. The S10 and P10 use traditional chain drivetrains. Belt drives are quieter, cleaner, and require far less maintenance, making them popular for year-round family riding.
Can the Tern GSD carry two children?
Yes, the GSD is designed to carry two children on the rear when fitted with the correct accessories. Common setups include the Clubhouse system, child seats, side rails, and footrests. Compatibility depends on child age and seating configuration, so it’s worth checking your setup before buying.
How much cargo can I carry on a Tern GSD?
The GSD has a maximum gross vehicle weight of 210 kg. To calculate usable cargo capacity, subtract the weight of the bike, batteries, accessories, rider, and passengers. This leaves the remaining allowance for bags, boxes, and equipment. Staying within this limit is essential for safe handling and braking.
Can the Tern GSD be stored in small flats or hallways?
Yes, the GSD is designed for compact storage despite its carrying capacity. It can park vertically, roll upright through narrow spaces, and fold flat at the handlebars. This makes it practical for flats, lifts, shared bike rooms, and narrow corridors.
Does the Tern GSD support dual batteries?
Yes, all GSD Gen3 models support dual batteries. A second battery can be added to increase real-world range for longer commutes, school runs, or commercial use. Both batteries can be charged on or off the bike for convenience.
Is the Tern GSD suitable for sharing between different riders?
Yes, the GSD is designed to fit riders from around 150 cm to 200 cm tall (4'11" - 6'7"). The adjustable cockpit, seatpost, and handlebars can be resized in seconds, making it easy for partners or family members to share one bike.
How long does Tern support parts for the GSD?
Tern commits to supplying spare parts for at least seven years for registered owners through Tern Care, alongside a 10-year frame warranty. Combined with Bosch’s long-term motor and battery support, this helps keep GSD bikes serviceable for many years.
Which Tern GSD model should I choose?
The right GSD depends on budget, maintenance preferences, and usage. The P10 offers best value, the P00 prioritises low maintenance, the S10 adds ABS and versatility, and the R14 targets heavy, high-mileage use. For a full comparison, see our 2026 GSD Gen3 range guide.
The Fully Charged Verdict
