The Tern 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 4’9″ – 6’5″—so mum, dad and the kids can all share it.

Despite everything it can haul, the GSD is actually the same length as a regular bike, so it fits anywhere a standard bike can. But there are lots of places a standard bike doesn’t fit. That’s why Tern designed it to pack down to 1/3rd its volume in only 10 seconds. That means you can store your utility bike in your house or flat, fit it in a lift, or stash it in a train for weekend getaways. It can also be stowed upright (on rear pegs) so will take up virtually no space in the garage.

Powered by Bosch’s Performance Line drive unit with the 400Wh Powerpack as standard (can be upgraded to 500Wh) the GSD is pre-fitted to accomodate a second battery for up to 1000Wh of battery capacity allowing a  range of up to 130 miles.

Please note: the accessories shown in the images here are not included as standard, the first main image shows the Tern GSD S10 as supplied without optional accessories – other images show the various accessories available as cost options – for example, the cargo panniers, the front and rear racks, seatpad, child seats, foot rests and sidekick bars shown in these images are all cost options that can be added separately to your shopping cart. We’re very familiar with the Tern GSD – and very happy to chat through the various configuration options, please contact our Woking store for helpful advice.
