Setup and Installation
Ensure the specifications and size of the mirror mount match your bicycle's handlebar diameter. This mirror is designed for handlebars with a diameter between 22-25mm.
Installation Steps:
- Prepare the Handlebar: Ensure the area on your handlebar where you intend to mount the mirror is clean and free of obstructions.
- Place the Base: Position the mirror mount base onto the desired location on your handlebar. If your handlebar is on the smaller side of the 22-25mm range, use the approximately 2mm thick shim provided for a secure fit.
- Secure the Base: Use a hex wrench to tighten the screws on the mirror mount base firmly. Do not over-tighten.
- Attach the Mirror Arm: Insert the connecting rod of the mirror into the base.
- Tighten Connecting Rod Screws: Use a hex wrench to tighten the screws that secure the mirror's connecting rod to the base.
- Adjust Mirror Angle: The mirror features a multi-angle rotatable universal ball joint and can rotate 360 degrees. Adjust the mirror to your preferred viewing angle.
- Final Fixation: Once the desired angle is achieved, use a wrench to ensure all connections are secure.

- 360° Free Adjustment: The rearview mirror is installed on the handlebar and can be adjusted from multiple angles and directions. Utilize the 360° rotation and the multi-angle rotatable universal ball to find the most suitable angle for your riding posture and visibility needs.
