Keep your essentials safe and your ride bright with the ROCKBROS Bike Saddle Bag AS-078-1! This waterproof bag not only protects your gear from the elements but also features a smart brake sensor tail light that lights up when you slow down. Perfect for adventurous cyclists who want to stay visible and prepared, it’s the ultimate combo of style, safety, and convenience on two wheels.
Innovative Integrated Brake-Sensing Tail Light
Features a built-in smart tail light with brake-sensing technology and dual-mode activation (light-sensing & vibration). Automatically brightens when braking, ensuring enhanced visibility and safety during night rides.
Structured, Sleek & Compact Design
Constructed with internal PP board support to retain a crisp, structured shape — even when empty. Lightweight and non-bulky, it delivers a streamlined silhouette without compromising durability.
Secure Tri-Point Attachment System
Equipped with three reinforced hook-and-loop straps for stable, rattle-free installation. Multi-point fastening ensures the saddle bag stays firmly in place, even over rough terrain, while protecting your bike’s frame from scratches.
Fully Waterproof Construction
Made from waterproof fabric with high-frequency welded seams to prevent water ingress. Keeps your essentials dry and protected in unpredictable British weather.
Optimised Capacity with Reflective Safety Trim
The 0.8L internal space is ideal for daily commuting gear or essential tools. Designed with a wide-opening zipper for quick access, and surrounded by a colourful reflective strip for added nighttime visibility.
