Still Small. Even More Useful.

With a 200 kg (440 lb) Maximum Gross Vehicle Weight, the GSD is ready to replace your car. It'll let you carry two kids plus groceries, or a whole lot of cargo—but it's the same length as a regular bike. Built-in dual-battery technology lets you ride all day, while space-saving features like FlatFold and Vertical Parking make the GSD incredibly easy to own and use.

The GSD has an adjustable cockpit that resizes in seconds and without tools to fit riders 4'11" - 6'5", so you can easily share it with your family. The updated frame geometry with a slacker seat tube angle and higher handlebars also means the GSD doesn't just fit—it's more comfortable, too.

The GSD's unique geometry makes for super stable riding, no matter what you're hauling (or how wiggly your kids are). The low center of gravity lets even smaller riders confidently manage heavy loads, and the step-thru frame makes getting on and off the bike a breeze. Plus, we've made it easier for the rider's feet to reach the ground at stops.

All GSD models now feature the best-in-class Bosch Cargo Line motor, which provides up to 85 Nm of torque for a smooth, natural-feeling ride, and 400% support to tackle serious hills. Top it off with Bosch's unparalleled service and expertise, and you can rest assured that your GSD's motor system will be safe and reliable for years to come.
