Frame Size

The all-new GSD brings serious upgrades to the family e-cargo bike you already love. With a redesigned frame and a max gross vehicle weight of 210 kg (463 lb), it’s tougher, smarter, and built to handle life’s heaviest loads. Whether that’s two kids, your shopping, or both. And the best part? It’s still about the same length as a regular bike, so you get all that carrying power without giving up everyday ease.

Still Getting Sh!t Done

The new GSD takes the family electric cargo bike to a whole ‘nother level. Smarter than ever and packing even more muscle with a re-engineered frame that handles a max gross vehicle weight of 210 kg (463 lb), it’ll help you carry 2 loved ones and weekly grocery hauls with newfound ease—but it’s similar in length to a regular bike to remain surprisingly manageable.

The Greener, Leaner Family Minivan

A more efficient alternative to the family minivan that’ll let you breeze past traffic jams and ditch the gas pump, the GSD comfortably carries up to 2 kids—from toddlers to teens—making school runs and shuffling from one activity to the next stress-free. It’ll even take an adult passenger, so you can keep the fun times rolling when it’s just you and your +1.

Carries Even More

Built on a stronger, stiffer hydroformed frame with optimized geometry to handle its biggest payload capacity yet, the beefed up GSD proves that you can haul, well, just about anything with the right bike and a little ingenuity—especially when you’ve got a best-in-class max gross vehicle weight of 210 kg (463 lb) at your disposal.

Rides Even Better

With a longer wheelbase and an all-new frame that brings the center of gravity even lower to the ground, the GSD offers next-level stability to complement its huge cargo capacity. Add to the mix a fine-tuned geometry for easier handling under heavier loads, and you’ve got a cargo bike you can confidently ride, no matter what you’re hauling.

Space-Saving Design and Vertical Rolling

The GSD flips upright to roll vertically, letting you easily push it down narrow hallways and into tight spaces like elevators. Perfect for apartment living and shared spaces, vertical rolling offers a simple, effective solution for getting your cargo bike to its storage spot.
