The Lamicall Waterproof Bike Frame Bag combines smart design and durability to give cyclists a convenient, secure place for essentials on the go. Made from rigid EVA with dual zippers and a rain cover, it keeps your phone (4.7″–7″), wallet, keys, and other items dry—even in wet weather. Thanks to a quick-release bracket, it's easy to mount/remove from both the top tube and stem within seconds—ideal for commuters and touring riders who need access and security without hassle.
