Low-Maintenance Drivetrain

A continuously variable Enviolo SP hub paired with a Gates CDX belt drive creates a smooth, quiet, and clean drivetrain. You can shift seamlessly without steps, even under load. The belt drive is virtually maintenance-free compared to a chain. This setup is perfect for year-round urban riding.

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.
