Follow these steps to correctly install the bicycle luggage carrier and pannier bag:
3.1. Bracket Installation
- Align the Bracket: Align the bracket with the lower fork position at the rear of your bicycle, ensuring proper spacing.
- Adjust if Necessary: If the bracket does not align perfectly with the rear fork, you can gently adjust its shape by bending it by hand and pressing it until it fits. The bracket is adjustable from 120-157mm to fit most bicycle models.
- Attach First Fixing Strap: Attach one fixing strap to one side of the bracket and tighten the screws to secure it. Important: Do not fix both sides simultaneously in the same direction initially.
- Loosen Middle Screws (Optional): To facilitate tightening the fixing strap screws, you may first loosen the middle screws on the bracket.
- Adjust Bracket Position: Once the first strap is loosely attached, adjust the overall position of the bracket to ensure it is centered and stable.
- Tighten First Fixing Strap: Fully tighten the screws of the first fixing strap.
- Attach Second Fixing Strap: Place the second fixing strap on the other side and secure it with screws. Ensure one fixing strap is on each side.
- Tighten Second Fixing Strap: Follow the same steps as the first side and tighten the screws of the second fixing strap.
- Tighten All Four-Sided Fixing Straps: Ensure all four fixing straps are securely tightened.
- Adjust Rear Seat Lever: Adjust the rear seat lever (if applicable) back to your required riding position.
- Final Tightening: The installation is complete once the middle screws are fixed and the bracket is not shaking.
