⚠ Important Safety & Care Instructions
Secure all Velcro attachment points before riding and check that the bag remains firmly attached.
Make sure the pannier and its straps cannot contact the wheel, tire, spokes, chain, pedals, brakes, or other moving parts.
Check clearance again after expanding the bag. Do not allow the expanded bag to interfere with your legs or bicycle controls.
Do not exceed the bag’s unspecified maximum load or the carrying limit of your rear rack.
The water-repellent treatment is intended for light rain and short-term exposure only. Protect electronics, documents, and other moisture-sensitive items from heavy rain and submersion.
Reflective strips do not replace required bicycle lights or high-visibility equipment.
Inspect the fabric, zippers, Velcro, side supports, and attachment points before each ride. Do not use the bag if it is torn, loose, cracked, or unstable.
Clean with a soft cloth and mild soap. Allow the bag to dry fully before storing it in an expanded or compressed state.
Keep away from open flames, excessive heat, sharp objects, and harsh chemicals.
