TERN GSD IS DESIGNED FOR EASY USE
Easy to Manage
Whether you’re carrying groceries or wriggling kids, the GSD is steady and easy to use. Its low centre of gravity helps you stay in control, even with a heavy load. The step-through frame makes getting on and off simple. Stopping also feels natural, as the design lets your feet touch the ground easily when you pause.
Easy to Transport
The GSD is made to replace your car for most trips. But when you need both, it’s ready to go. It folds down in seconds to about a third of its size. You can easily pop it into the back of a minivan or small SUV—no big bike rack is needed. You can even fit two!
Small-Space Friendly
Bikes can be a pain to store, especially when space is limited or you have an elevator. The GSD solves this issue by parking upright. It takes up no more space than a large houseplant. This feature makes it a game-changer for apartment living and small homes.
Tern GSD Carries Your Family
Whether you're doing the school run, going to the park, or planning a night out, the GSD has you sorted. Begin with two child seats for the little ones. As they grow, switch to the Clubhouse. When they're older, they can even take a turn riding along—it's that simple to share. And for date night? The Captain’s Chair turns your ride into a comfy cruiser for two.
Tern GSD is Cargo-Ready
The GSD is built to carry more than just you or your family. It's perfect for your daily adventures. With smart add-ons for various cargo, you can load up without fear of shifting or tipping. No matter, shopping, DIY tools, or garden centre finds, Tern GSD will fit it all. Suddenly, you realise that the bike is your go-to for much more than commuting.
Tern GSD is build to Year-Round Riding
No one enjoys a soggy school run, especially the kids. That’s where the Clubhouse Fort comes into play. It transforms the GSD into a comfy, weather-ready ride. Your little passengers will stay warm, dry, and much happier, no matter the season.
