Tern GSD S10

The Tern GSD S10 is enormously useful and surprisingly small. It is equipped with a powerful Bosch Cargo Line drive (85 Nm) and offers space for two children as well as the entire week’s shopping, carries more than 170 kg and is not even 180 cm long – and thus shorter than a normal pedelec.

It fits anywhere a standard bike can. But there are lots of places a standard bike doesn’t fit. That’s why we designed it to pack down to 1/3rd its volume in only 10 seconds. That means you can store your utility bike in your urban apartment, fit it in the elevator, or stash it in a train for weekend getaways. Plus, it adjusts to fit riders from 150 – 195 cm—so mom, dad and the kids can all share it.

Features

Bosch Cargo Line Motor
A powerful motor that’s cut out for heavy loads and hilly roads. Natural-feeling e-assist with up to 85 Nm of torque and 400% support.

Stronger, Stiffer Frame
The GSD has always been super strong, but we’ve made it even beefier for a better ride. The added stiffness prevents side-to-side motion, even when heavily loaded.

Atlas Lockstand
The best-in-class Atlas Lockstand features unique Auto Lock and Remote Unlock features for safe and simple loading and unloading.

Atlas Wheels™
The GSD’s wheels may be small, but they’re strong enough to carry big. Custom-designed to withstand the 200 kg max gross vehicle weight of the GSD.

Frame-Integrated Rack
The GSD has a max gross vehicle weight of 200 kg, and the rear rack can carry up to 100 kg. Whether it’s an adult passenger, two weeks’ worth of groceries, or stuff for a big DIY project—the GSD carries virtually anything.

Dedicated Trailer Mount
Easy to use, very secure, and optimized to prevent trailer tilt. Compatible with Thule, Burley, and Weber trailers, no adapters needed.

Integrated Lower Decks
The rugged Integrated Lower Decks offer built-in support for cargo and passengers’ feet. Got a truly oversized load? Add the Sidekick Wide Decks for extra room and even more load capacity.

Easy-Step Frame Design
Updated frame geometry makes the GSD comfier for riders of all sizes. A slacker seat tube angle and higher handlebars create a better-fitting cockpit and a more upright riding position. Plus, it’s now easier for riders’ feet to reach the ground at stops.

Custom Suspension Fork
We built a special suspension fork to add comfort and control while safely handling the GSD’s massive 200 kg MGVW.

Andros Stem
The unique Andros Stem lets you change the height and angle of the handlebars in seconds and without tools, creating a comfy riding position whether you’re tall or small.

RearStop Brake Light
Let drivers know to give you space when you’re stopping or slowing down. Always on, day or night, with enhanced side visibility.

Full Chainguard
The chainguard helps you stay tidy (no pant-rolling required) and prevents long skirts and loose pants from getting caught in the chain or belt.

Integrated Wheel Guard
A full-coverage rear wheel guard protects the rider and passengers from splashes of muddy water and prevents clothes and shoelaces from being caught in the wheel.

Magura MT-5 4-Piston Disc Brakes
A bike that can carry this much calls for some serious stopping ability, and these brakes deliver. They can quickly bring a fully loaded GSD to a strong, confident stop.

All Day Battery
Equipped with Bosch dual-battery technology, the GSD is wired from the get-go to accommodate two batteries—meaning you can get a second battery when you’re really sure you need it, without having to worry about rewiring your bike. Just plug it in and you’re good to go.
