The Full Scoop on the Tern GSD S10
With a 440 lb Maximum Gross Vehicle Weight, the Tern GSD S10 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 Tern GSD S10 incredibly easy to own and use. The Tern GSD S10 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.
