Fenix BC45R – High-Performance Mountain Bike Light with Dual Beam & Wireless Remote

The Fenix BC45R is Fenix's most powerful bike light, built for the extreme demands of mountain biking and adventure racing. Blasting 3,300 lumens out to 938 feet (286 meters), it delivers the kind of trail coverage and long-range visibility serious off-road riders need when the terrain gets remote and the stakes get real.

Independent Spotlight & Floodlight — Your Beam, Your Way

What sets the BC45R apart is true independent control over its spotlight and floodlight sources. Run the spotlight alone for long-range trail visibility at speed, switch to floodlight for wide-angle close-range coverage on technical sections, or combine both for total trail awareness. One SFT-40 cold white LED handles the spotlight while four SST12 cold white LEDs power the flood — each rated for 50,000 hours of use.

OLED Display & Wireless Remote — Total Control, Mid-Ride

A built-in OLED display gives you real-time data on battery level, active light source, current lumen output, and charging status — no guessing how much runtime you've got left on a long backcountry ride. The included wireless remote switch puts Instant Turbo and Flash modes right at your fingertips, so you can adjust output without taking a hand off the bars at a critical moment.

9 Modes. 6+ Hours on High. Built for the Long Haul.

Nine total lighting modes — three high beam levels, four low beam levels, Turbo, and Flash — give you the flexibility to match output to terrain and ride length. Powered by two replaceable 18650-3400mAh batteries, the BC45R delivers over 6 hours of runtime on High and up to 59 hours at lower settings, so it's ready for everything from a quick night lap to a full endurance race.

A6061-T6 Aluminum. IP66 Rated. Quick-Release Mount.

Constructed from durable A6061-T6 aluminum alloy and rated IP66 for heavy rain resistance with 1.5-meter impact resistance, the BC45R is built to take the abuse of rugged trail riding. A quick-release mount makes it fast to swap between bikes, and an inner-waterproof USB-C charging port keeps charging simple without compromising weatherproofing.
