The Fenix BC26R Rechargeable Bike Light will keep you rolling even after the sun goes down (or before it comes up.) Its rechargeable 5000mAh lithium-ion battery powers a 1600-lumen LED and allows for runtimes of up to 65 hours on the lowest brightness level. The 100° floodlight beam offers a wide field of view, making it much easier to see while turning corners. Attach and remove the bike light quickly with the included quick-release bike mount. The BC26R's dustproof, waterproof, and shockproof housing is built to withstand the elements.
