2.6 Optical Design for City Cycling
The light features a 125° floodlight angle, designed for safer city cycling:
- Adjust the light angle up and down to ensure the main light spot illuminates the waist area of people approximately 4-25 meters in front of you. This provides sufficient light distance without dazzling oncoming pedestrians or drivers.
- Use low luminance mode for slow rides and high luminance mode for quicker rides to optimize visibility and battery life.
