This saddle bag with tail light is perfect for all cyclists, especially for night riders. Inflatable, soft and foldable, it weighs just 250 g, and is easy to attach to the bike, featuring a quick-release function. The tail light can be stored in the saddle bag. The exclusive patented technology uses only a minimal LED to achieve light across a large area. The ultra-efficient power source, using 3 AAA batteries, gives usage of up to 95 h before recharging is necessary. The up-to-the-minute tail light is visible within 200 m. The saddle bag is waterproof, not just spill-resistant, meaning heavy rain and sunny days are all the same to it.
