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.

How do you know what size of bike you should buy?

A good place to start is using the sizing charts included for each bike on the info page. If you're in the middle of the recommended height range for a specific size then usually that's the correct one to go with. If you find yourself overlapping sizes at either the top or bottom of the height recommendation than sizing up or down could be a consideration.

For more relaxed fitting "city-style" bikes sizing is less crucial because often they will have adjustable stems and offer more overlap in sizing. Smaller bikes will be slightly easier to manage when starting and stopping while larger bikes will feel more stable when riding. Most often we recommend sizing down in this category.

Bikes that have a more aggressive riding position i.e. road, gravel and mountain bikes sizing is more important. In these categories we usually look closely at 3 numbers, reach, stack, and top-tube length.
