Step-by-Step Installation:

- Loosen Middle Screws (Optional): To facilitate the tightening of the fixing strap screws, you can first loosen the middle screws on the bracket.
- Adjust the Bracket: Make any final adjustments to the bracket's position.
- Tighten First Fixing Strap: Securely tighten the screws of the first fixing strap.
- Attach Second Fixing Strap: Place the fixing strap on the other side and fix it with screws. Note: First fix one fixing tape on each side, do not fix two on the same side.
- Tighten Second Fixing Strap: On the other side, follow the same steps and tighten the screws of the fixing band.
- Tighten All Four-Sided Fixing Straps: Ensure all four fixing straps are securely tightened.
- Adjust Rear Seat Lever: Adjust the rear seat lever back to the required position if applicable.

6. Operating Instructions
Once installed, the NEWBOLER Bicycle Luggage Carrier is ready to support your bikepacking and travel needs.
- Attaching Bags: The carrier is designed to work with various bicycle bags, including tail bags, front fork bags, and large-capacity panniers. Use the integrated attachment points and your bag's straps to secure them firmly.
- Weight Distribution: For optimal stability and handling, distribute the weight of your luggage as evenly as possible across the carrier.
- Pre-Ride Check: Before each ride, especially with a loaded carrier, perform a quick check to ensure all bags are securely attached and the carrier itself is firmly mounted to the bicycle.


7. Maintenance
To ensure the longevity and optimal performance of your bicycle luggage carrier, follow these simple maintenance guidelines:
- Cleaning: Wipe down the carrier with a damp cloth after use, especially after riding in wet or muddy conditions. Avoid harsh chemicals that could damage the aluminum alloy finish.
- Inspection: Periodically inspect all screws, bolts, and straps for tightness. Tighten any loose fasteners. Check the aluminum frame for any cracks, bends, or signs of fatigue.
- Silicone Gaskets: Ensure the silicone gaskets remain in place and are not worn out to continue protecting your bike's paint. Replace if necessary.
- Storage: When not in use, store the carrier in a dry place to prevent any potential corrosion, although the aluminum alloy is highly resistant.
8. Troubleshooting
- Carrier feels unstable: Double-check all four fixing straps and the middle screws to ensure they are tightened securely. Ensure the bracket is properly aligned with the bicycle's rear fork.
- Bags are rubbing against the wheel: Re-adjust the bracket and ensure it is positioned correctly to provide adequate clearance between the bags and the wheel/spokes. Ensure bags are securely fastened and not sagging.
- Difficulty in installation: Refer to the detailed step-by-step guide and the installation video. Ensure the bracket is adjusted to the correct width for your bicycle's rear fork. Loosening the middle screws first can help with strap tightening.
- Scratches on bike frame: Verify that the silicone gaskets are correctly positioned at the contact points between the carrier and the bike frame. If missing or damaged, replace them.
