Bicycle Waterproof Bag with Ultimate Waterproofing Capability
We are well aware of the annoyance of encountering heavy rain during a bike ride. The waterproof bag for bicycles is made of military-grade TPU coating material and combines high-frequency seamless welding technology to achieve IPX7-level waterproofing (no leakage after being submerged in water for 30 minutes at a depth of 1 meter). Whether it’s a downpour, muddy roads, or water-crossing rides, your equipment will always stay dry and worry-free.
Exceeding Industry Standards of Quality Control
We conduct the most rigorous tests to ensure the outstanding performance of each waterproof bag.
- We perform high-pressure rain tests in a simulated heavy rain environment (1000mm/H water pressure for 48 hours),
- We conduct load-borne jolting tests for long-distance cycling, passing the 6-hour continuous jolting test under a 20kg load,
- We carry out high and low temperature tests in simulated environmental conditions (-20° – 50° extreme environment) to ensure that the materials do not deform under any circumstances.
