Elevate your product offering with our innovative Waterproof Bicycle Bag, engineered for the modern cyclist. Constructed from advanced TPU coated nylon with fully welded seams, this bag provides superior waterproof protection, keeping essentials dry and secure in all weather conditions. Its streamlined profile (3.5” Tall x 8.5” Long) minimizes wind resistance, while the robust strap-on system ensures stable attachment to the bicycle's top tube and stem.

More than just a Bicycle Top Tube Bag, it's a comprehensive cycling companion. Featuring dual-layer storage, the main pocket with a hardware closure securely accommodates plus-sized phones, while outer pockets offer quick access to gels, salts, or small tools. A standout feature is the integrated, adjustable holder for the included 500ml BPA-free soft flask, providing convenient hydration without occupying bottle cage space. A durable YKK zipper guarantees smooth, long-lasting performance. As a B2B manufacturer, we offer full OEM/ODM capabilities, allowing for custom dimensions, colors, materials, and branding to perfectly align with your brand's vision and market strategy, making this the ideal Bicycle Top Tube Bag for your product line.
