Ultra-bright Bike Light
The Nitecore BR25 is an ultra-bright bicycle light that enhances your visibility and performance while keeping you and others safe. Combining its maximum output of 1400 lumen and evenly diffused reflector, the BR25 gives you a broader short-range coverage while extending out up to 178 yards in distance. Its uniquely designed reflector shape cuts the beam above eye level which avoids blinding pedestrians and oncoming drivers or riders. BR25 is an excellent bike light for road cycling, mountain biking, BMX, or just casual neighbourhood rides.

USB-C Rechargeable
Inside the BR25, you will find a 5000mAh NL2150R USB-C rechargeable 21700 battery that provides up to 60 hours of runtime on low. Additionally, the BR25 can be powered by a compatible 18650 or 2x CR123A using the included battery sleeve so you never need to take a break from riding.

Trusted Riding Companion
The BR25 is a well-rounded premium bike light. Its quick-release hard bike mount tightly secures the light on the bar while still easy to unmount. Adjust among 4 brightness levels and a flashing mode via its easy-to-reach single-switch design. Rated IP68 waterproof and made from durable impact-resistant aluminium the BR25 is ready to go the distance in any climate.
