Bike frame bag Wildman E4 Waterproof 1.5L Black — under‑top tube storage

Wildman E4 is an extremely compact, waterproof triangular bike frame bag designed to fit under the top tube. With a 1.5 L capacity, the bag stores a phone, documents, tools and small repair kits while maintaining a low profile and minimal air resistance. Constructed from PU and EVA, the outer shell is water resistant, easy to clean and resistant to mechanical damage. Internal stiffening preserves the shape during impacts, and two mesh compartments serve as organizers.

Advantages

The Wildman E4 combines a rigid inner structure with a water-resistant PU+EVA cover to protect contents from rain and mechanical stress. A laminated zipper provides tight closure and easy access, while long Velcro straps secure the bag to the frame in a stable position. Its triangular low-profile design reduces air resistance and avoids interference with pedaling.

Suitable for

• Storing a phone and documents

Usage recommendations

Do not overload the bag beyond its 1.5 L capacity; avoid storing sharp metal objects without protection to prevent internal damage. For prolonged wet conditions, periodically check and dry the zipper area to maintain a tight seal and prolong product life.
