Every cyclist knows it's smart to take along some basic tools, an extra tube, patch kit, and maybe a canister or two of CO2 before you head out-especially on those longer rides. Our SaddleLite LED Bike Bag packs all of that, and has the added plus of a bright red, weather - resistant LED sewn into its reflective back, which creates a tail light that oncoming traffic can see when you're riding in the dark. A quality saddle bag made with recycled PET water-resistant fabric with a roomy bright white interior for easily finding items. Outlined with a passive reflective trim and a bright LED with two modes - press once for steady glow, twice for continuous flash (the specially-designed loop behind it makes it easy to activate). It's also removable so the bag can be washed without damaging the light. The attached flexible, reusable Gear Tie allows for safe, easy, and adjustable seat post installation, and the SaddleLite's reflective trim provides secondary passive visibility for added safety. Powered by two replaceable 2016 lithium batteries, included.
