Performance & User Experience
Battery & Range

- If you regularly ride long distances, the optional 160Wh range extender ($550) can increase range to 75 miles in Eco mode.

Ride Quality & Handling
- The TQ-HPR50 motor is exceptionally quiet and smooth, making the ride feel more natural.
- The lightweight frame and carbon fork improve handling, especially when navigating city streets.
- The Shimano CUES drivetrain delivers smooth shifting, even when carrying extra weight.
- Hydraulic disc brakes provide strong, reliable stopping power, even in wet conditions.
