Tern GSD S10 - Gen3 - Midnight Blue

The Tern GSD S10

The new Gen 3 GSD is the most advanced family cargo bike Tern has ever built. Stronger, smarter, and more refined, it’s designed to carry children, adults, pets, and serious cargo, without feeling intimidating to ride or difficult to live with.

Despite its huge load capacity, the GSD is similar in length to a standard bike, making it easy to manoeuvre through traffic, park vertically, or store in tight spaces. For families looking to replace car journeys with something cleaner, calmer, and more enjoyable, this is the benchmark.

Understanding Tern Models – A Quick Guide

Tern's lineup is incredibly capable! You can think of Tern eCargo bikes as divided into three main categories:

1. One-child capability / Cargo gear:
   HSD / NBD / Quick Haul

2. Two-child capability / Cargo gear:
   GSD / Orox / Quick Haul Long

3. Folding e-bikes:
   Vektron

How to understand Tern’s model codes

• D … “Derailleur” with basic to mid-level components

• P … Premium derailleur or belt-drive setups

• S … Sport derailleur setups with higher-spec components

• “00” models … Enviolo hub + belt drive (smooth, low-maintenance)

• R14 … Rohloff 14-speed hub + belt drive + electronic shifting

Simple rule: Higher letter/number = higher performance, more premium features.

GSD Gen 3 – Designed Around Family Life

The GSD is built to carry up to two kids (from toddlers to teens), a full grocery shop, or even an adult passenger—without compromising stability or ride quality.

• Best-in-class 210 kg max gross vehicle weight

• 100 kg rear rack rated for passengers or cargo

• Low centre of gravity for exceptional balance

• Compact footprint for city riding and storage

School runs, activities, shopping, weekend adventures—it’s all easier, quieter, and more fun on a GSD.

Ride Feel & Comfort

The Gen 3 GSD rides better than ever thanks to a re-engineered frame and longer wheelbase:

• Ultra-low 49 cm step-through for easy mounting

• Longer wheelbase and lower centre of gravity for next-level stability

• Adjustable cockpit fits riders 150–200 cm without tools

• Suspension fork and Cane Creek suspension seatpost smooth out rough roads

Stable, confidence-inspiring, and comfortable—even when fully loaded.

Safety Comes First

The GSD Gen 3 sets a new benchmark for cargo bike safety:

• DIN 79010 certified for cargo bike loads up to 210 kg

• UL 2849-certified Bosch eBike system

• Integrated rear wheel guards protect passengers

• Always-on RearStop brake light for visibility

• Ultra-bright 700-lumen headlight with Hi/Lo beam

This is a bike designed to protect what matters most.

Electrics – Bosch Smart System Power

The GSD S10 Gen 3 features Bosch’s Smart System, bringing digital connectivity and advanced safety to everyday riding:

• Motor: Bosch Cargo Line – 85 Nm torque, 400% support

• Battery: Bosch 545 Wh PowerPack, dual-battery ready (up to 1600 Wh max)

• Display: Bosch Kiox 300 with LED remote

• Bosch eBike Flow app: navigation, ride customisation, updates, theft protection

Strong, smooth, and intelligently connected—this is true car-replacement power.

Bosch Anti-Lock Braking System (ABS)

Exclusive to the S10 and R14 models, Bosch eBike ABS dramatically improves braking control:

• Prevents wheel lock-up under emergency braking

• Maintains steering control on wet or slippery roads

• Shorter, smoother stopping distances under load

Paired with Magura 4-piston ABS brakes, this is a major leap forward in cargo bike safety.

Gearing – Shimano Deore 1×10 (S10)

The S10 uses a robust Shimano Deore derailleur setup designed for loaded riding:

• Wide-range 11–42T cassette

• Shadow+ derailleur for chain stability

• Durable, e-bike-rated components

Reliable, efficient, and ideal for hilly routes and daily family use.

Carrying Capacity: Built to Haul More
