Fenix BC45R Dual-Distance Mountain Bike Light with Remote Switch

The Fenix BC45R is a mountain bike light built for riders who push into technical terrain after dark. Its dual-beam system delivers up to 3,300 lumens and a 938-foot beam distance, with integrated high and low beams that run together or independently, giving you precise control whether you're sprinting open trail or threading tight switchbacks. A wireless remote switch mounts within easy thumb reach so you can adjust output without taking your hands off the bars, and an OLED display keeps battery level and mode status visible at a glance.

Built for real trail abuse, the BC45R runs on two included 3,400mAh rechargeable 18650 batteries for up to 59 hours of runtime, recharging via a waterproofing-treated internal USB-C port. The A6061-T6 aluminum body is drop-tested to 1.5 meters and IP66-rated against water and dust, holding up through mud, rain, and rough landings. A shock-proof, quick-release mount fits handlebars from 22 to 35mm with included shims, and a flashing safety mode adds visibility during dawn, dusk, or road transitions — genuinely purpose-built gear for serious mountain biking.
