Description

Comfortable thanks to its front suspension, ergonomic saddle, and wide tires, it’s always ready for an urban adventure. It glides over cobblestones and takes off smoothly thanks to its 5-speed rear hub, which allows you to shift gears effortlessly with a simple twist, even when stationary. Its belt drive ensures a smooth, silent ride and requires very little maintenance.
