Tern GSD R14
The Tern GSD R14 2026 is the kind of bike that quietly replaces a car without trying to make a big deal out of it. It’s built for real everyday life in the city: school runs, groceries, work commutes, and everything in between.
What makes it special is how easy it feels despite being a heavy-duty cargo machine. The Bosch motor does the hard work, the Rohloff electronic 14-speed hub keeps shifting smooth and automatic, and the belt drive means almost no maintenance.
It’s stable, strong, and surprisingly simple to live with — even when fully loaded or riding every day in all weather.
