Fenix BC45R High Performance Bike Light
The Fenix BC45R is Fenix’s most powerful bike light, purpose-built for mountain biking and technical trail riding. Its independent spotlight and floodlight system delivers a combined 3,300 lumens and illuminates up to 938 feet ahead – run them independently for focused distance or wide-angle coverage, or activate both together for maximum trail visibility.
The BC45R’s wireless remote switch mounts within thumb’s reach on your handlebar, letting you adjust brightness, activate Instant Turbo, or switch between modes without ever touching the light or leaving the bars. An OLED display keeps battery level, current mode, and lumen output visible at a glance. Powered by two included Fenix 18650 rechargeable batteries, it delivers 6+ hours of runtime on High and recharges via USB-C. Built from A6061-T6 aluminum with an IP66 rain-resistance rating and 1.5m impact resistance, the BC45R is ready for whatever the trail throws at it……$159.95
