Fenix BC45R High-Performance Mountain Bike Light
High-Performance Mountain Bike Light
The Fenix BC45R is a high-performance mountain bike light made for long nights on the trail. One SFT-40 and four SST12 LEDs light the way with 3,300 lumens out to 286 meters, and the independent high-beam and low-beam systems let you dial in exactly the light you need. A wireless handlebar remote lets you flick to Turbo or switch modes without looking down, while the OLED display keeps mode, brightness, charging status, and battery percentage in view. Two replaceable ARB-L18-3400 18650 batteries keep the ride going, and the inner-sealed USB-C port fast-charges at 18W — roughly 3.5 hours to full. Built from A6061-T6 aluminum, IP66 sealed and 1.5-meter drop rated, it clicks on and off 22–35mm handlebars in seconds with no tools.
