Setup and Installation
The M-Wave Spy Space Barend mirror is designed for installation on the left handlebar end. Follow these steps for proper installation:
- Prepare Handlebar: Ensure the end of your bicycle handlebar is clear of any grips or plugs that might obstruct the mirror's insertion. The mirror is designed to fit into the hollow end of most standard handlebars.
- Insert Mirror: Gently insert the inner clamp mechanism of the mirror into the open end of your left handlebar.
- Tighten Clamp: Using an appropriate hex key (not included), tighten the bolt located at the end of the mirror's mounting arm. As you tighten, the inner clamp will expand, securing the mirror firmly within the handlebar. Do not overtighten, but ensure the mirror is stable and does not rotate freely.
- Adjust Angle: Once secured, adjust the mirror's arm and head to achieve your desired viewing angle. The mirror offers 3-dimensional adjustability for optimal positioning.

Operating Instructions
Once installed, the M-Wave Spy Space Barend mirror is ready for use. Its primary function is to provide a rear view, enhancing situational awareness while cycling.
- Initial Adjustment: Before your first ride, sit on your bicycle in your normal riding position. Adjust the mirror so you have a clear view of the road behind you, including traffic. The 3-dimensional adjustability allows for fine-tuning.
- Regular Checks: Periodically check the mirror's position during your ride, especially after encountering bumps or vibrations, to ensure it hasn't shifted.
- Convex Lens: The mirror features a convex lens, which provides a wider field of view. Objects in the mirror will appear smaller and farther away than they actually are. Use this information to judge distances safely.
Maintenance
To ensure the longevity and optimal performance of your M-Wave Spy Space Barend mirror, follow these maintenance guidelines:
- Cleaning: Clean the mirror surface regularly with a soft, damp cloth. For stubborn dirt, use a mild soap solution and then wipe dry. Avoid abrasive cleaners or materials that could scratch the anti-reflective coating.
- Inspection: Periodically inspect the mirror and its mounting for any signs of damage, cracks, or looseness.
- Tightness: If the mirror feels loose, re-tighten the inner clamp bolt as described in the "Setup and Installation" section.
- Storage: When not in use for extended periods, store the bicycle in a dry, temperate environment to prevent material degradation.
Troubleshooting
