About this ebike...
Enormously Useful. Surprisingly Small.
The GSD is designed to carry two kids, a week’s worth of groceries, or 180 kg of cargo, but it’s only 180 cm long—the same length as a standard bike. With Tern’s best-in-class folding technology, it packs down small enough to fit in a VW Touran or an urban apartment. Plus, it adjusts to fit riders from 150 – 195 cm—so mum, dad and the kids can all share it.
With a range of accessories to fit this versatile load platform, it’s a very attractive alternative to a car or small van. The GSD boasts cargo-bike capacity, despite its city-bike footprint—up to 180 kg (400 lbs.) including rider. Build it up with Cargo Hold Panniers and the Shortbed and Transporteur racks, to carry industrial strength Eurocrates, a week of groceries or a family picnic plus the kitchen sink.

Is this the right ebike for me?
If you are looking to ditch the car, increase your fitness, reduce your costs, carry kids and/or cargo, have fun, reduce pollution, save the planet or maybe all of these, then the Tern GSD gives you a real practical way to do this. It’s designed to carry up to 180kg, and its strong versatile frame can hold a range of accessories from child sets to cargo boxes and panniers.
It’s also easy and great fun to ride, and with its dual battery option the range is huge – we guesstimate up to 125 miles. Storing it is made as easy as possible, it’s the same length as a regular bike, believe it or not, and the handlebar stem folds down to reduce its height if you want to load it into a car or other space.
SPEAK TO OUR EBIKE EXPERTS "The Tern’s big selling point is that for all its cargo capacity and versatility, it’s actually no longer than a standard big-wheeled bike."
