Packing List
Please verify that all the following components are included in your package:
- Bike Mount (main clamp and arm assembly)
- GoPro Adapter
- Spare Nut
- Silicone Spacer

Setup and Installation
Follow these steps to securely attach the Ulanzi CM025 mount to your bicycle or motorcycle handlebar:
- Prepare the Handlebar: Identify a suitable section on your handlebar or pipe with a diameter between 8-35mm. Ensure the surface is clean and free from obstructions.
- Insert Silicone Spacer: Place the silicone spacer inside the clamp of the bike mount. This pad doubles the anti-slip performance and protects your handlebar from scratches.
- Attach the Mount: Open the clamp and position it around the handlebar. Tighten the main screw until the clamp is snug.
- Secure the Clamp: Use the independent knob on the clamp to firmly lock it in place. Ensure there is no movement or looseness.
- Attach GoPro Adapter: If using a GoPro or compatible action camera, attach the provided GoPro adapter to the 1/4" screw on the mount's ball head arm.
- Mount Your Camera: Attach your action camera to the GoPro adapter or directly to the 1/4" screw if your camera supports it.
- Adjust Angle: Loosen the independent knob on the ball head arm to adjust the camera's angle. Once the desired angle is achieved, tighten the knob securely to prevent movement during recording.

Operating Instructions
The Ulanzi CM025 mount features a 360° dual-directional adjustment, allowing for flexible camera positioning to capture various perspectives.
- Angle Adjustment: Loosen the independent knob on the ball head arm to freely rotate your camera 360 degrees and tilt it in multiple directions. This allows for quick switching between portrait and landscape orientations, or adjusting for different shooting angles.
- Secure Positioning: Once the desired camera angle is set, firmly tighten the knob to lock the camera in place. This ensures stability and prevents unwanted movement during your ride.
- Versatile Mounting: The universal holder can be clipped onto various positions beyond just handlebars, including other pipes or even under the seat, offering diverse shooting opportunities.


Maintenance
To ensure the longevity and optimal performance of your Ulanzi CM025 mount, follow these simple maintenance guidelines:
- Cleaning: Wipe the mount with a soft, damp cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive materials that could damage the aluminum alloy finish or silicone pads.
- Inspection: Periodically check all screws and knobs to ensure they are tight. If any component feels loose, tighten it gently but firmly.
- Storage: When not in use, store the mount in a clean, dry place away from extreme temperatures and direct sunlight.
Troubleshooting
If you encounter any issues with your Ulanzi CM025 mount, refer to the following common problems and solutions:
- Shaky Footage: If your recorded footage appears shaky, ensure that all knobs, especially the one on the ball head arm and the main clamp screw, are securely tightened. Verify that the silicone spacer is correctly positioned within the clamp to provide maximum grip.
- Mount Slipping: If the mount slides on the handlebar, loosen the main clamp screw, reposition the silicone spacer if necessary, and re-tighten the clamp firmly. Ensure the handlebar diameter is within the 8-35mm range for proper fit.
- Difficulty Adjusting Angle: If the ball head arm is stiff or difficult to adjust, ensure the independent knob is sufficiently loosened. Do not force the adjustment; if it remains stiff, check for any debris or damage.
