How to use

Position the bag inside the bike frame triangle with the zipper facing outward for easy access.

Usage recommendations

For optimal convenience and safety, carry only essential, lightweight items and check strap tightness before each ride. Regularly clean the exterior fabric with a damp cloth and allow the bag to dry fully to maintain material integrity. Avoid storing wet items inside to prevent mildew and unpleasant odors.
