Frame Size

The Tern GSD is a compact powerhouse designed to haul heavy loads easily. With a 200 kg capacity, it can replace your car for school runs, grocery trips, or heavy cargo while being the same length as a regular bike. The Tern GSD, or “Get Stuff Done,” makes life simpler and more enjoyable. It helps you live sustainably, stay active, and have fun getting around. Dual-battery technology allows for all-day riding, and vertical parking makes storage a breeze.
The Tern GSD is built for the whole family. It adjusts easily and fits riders from 150 to 195 cm (4'11" to 6'5"), so everyone can use it. A full range of accessories lets you transport kids, dogs, shopping, or even a second adult in any weather. Its low center of gravity and stable design make heavy loads feel light, so you can carry everything without breaking a sweat.

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.

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.
