40L Ebike Battery Bag - Waterproof Hard Shell Rear Rack Bag with Reflective Strips & Shoulder Straps for E-Bikes

【Secure Battery Storage Design】
This e-bike battery bag features a dedicated, fully enclosed battery compartment and a removable protective divider. This design securely isolates your battery from other items to prevent scratches, impacts, and damage during daily commutes or outdoor rides, helping extend your battery's life and performance.

【Large 40L Cargo Space】
Thanks to its expandable side panels and removable dividers, this rear rack bag offers a spacious 40L capacity—ideal for commuters and outdoor enthusiasts. Easily store bike tools, air pumps, bike locks, riding clothes, power banks, sunglasses, and more. All your cycling essentials can come along for the ride.

【Multi-Scenario Versatility】
Complete with a padded top handle and an adjustable shoulder strap, it’s not just an e-bike rack bag. It also doubles as a work or school carryall, or a convenient shoulder bag for hiking, camping, or ski trips. Adapt it to your lifestyle, whether you're commuting, touring, or exploring the outdoors.

【Triple-Layer Weather Protection】
Built for all-weather use, this bag delivers three layers of waterproof defense. The sides are made of molded EVA hard shell for structure and weather resistance; all zippers are fully sealed; and the roll-top closure provides an extra physical barrier against rain. Ride with confidence knowing your battery and electronics stay completely dry.

【Quick-Mount & Safety Features】
Five heavy-duty hook-and-loop straps (three bottom, two side) allow for fast installation and secure attachment to any standard bike rack. It stays firmly in place on rough trails or busy streets. Reflective strips and an integrated taillight mount also enhance visibility day and night, adding an extra level of safety to your ride.
