Setup and Installation
Follow these steps to securely attach the BackLoader 6L to your bicycle's saddle and seatpost.
- Prepare the Bag: Ensure the waterproof inner bag is correctly inserted into the main bag.
- Attach to Saddle Rails: Position the bag under your saddle. Thread the two upper straps through the saddle rails. Securely fasten the buckles, ensuring the bag is centered and stable.
- Secure to Seatpost: Wrap the lower strap around the seatpost. Fasten the buckle and pull the strap tight to prevent the bag from swaying during rides. Ensure there is adequate clearance between the bag and the rear wheel.
- Adjust for Stability: Tighten all straps evenly to minimize movement. The bag should be firm and not interfere with pedaling or wheel rotation.

Operating Instructions
Proper loading and sealing are crucial for optimal performance and protection of your items.
- Loading the Inner Bag: Place your items inside the 6L waterproof inner bag. Distribute weight evenly to maintain balance.
- Sealing the Inner Bag: Roll down the top of the inner bag at least three times to create a watertight seal. Expel as much air as possible before sealing to reduce bulk.
- Inserting and Securing: Slide the sealed inner bag into the main BackLoader compartment. Use the external compression straps to cinch down the bag, further stabilizing its contents and reducing its profile.
- Rear Light Attachment: Utilize the integrated clip holder on the rear of the bag to attach a compatible rear bicycle light for increased visibility.

Maintenance
Regular maintenance will extend the life and performance of your BackLoader 6L.
- Cleaning: Wipe the exterior of the bag with a damp cloth and mild soap. Do not use harsh chemicals or abrasive cleaners. Rinse thoroughly and allow to air dry completely before storage.
- Inner Bag Care: The waterproof inner bag can be rinsed with water. Ensure it is dry before storing to prevent mildew.
- Strap Inspection: Periodically check all straps and buckles for wear, tears, or damage. Replace any damaged components to ensure secure attachment.
- Storage: Store the bag in a cool, dry place away from direct sunlight when not in use.
Troubleshooting
- Bag Sways Excessively:
Solution: Ensure all straps (saddle rail and seatpost) are tightened evenly and securely. Distribute the load inside the bag more evenly. - Items Inside Get Wet:
Solution: Verify that the waterproof inner bag is properly sealed by rolling the top down at least three times. Check for any punctures or damage to the inner bag. - Insufficient Clearance with Rear Wheel:
Solution: Adjust the bag's position on the saddle rails, moving it slightly forward if possible. Ensure the seatpost strap is tightened to pull the bag upwards. If the issue persists, your bike frame or saddle type may not be fully compatible with this bag size.
