The Fenix BC28R smart bike light combo delivers an integrated head and tail lighting system built for cyclists who ride after dark. The front and rear units communicate directly, giving you full control of the tail light from the handlebar and clear visibility of its current mode on the headlight display.

This synced design reduces distraction and improves safety on night commutes, endurance rides, and longer outdoor cycling adventures. The headlight produces up to 2500 lumens with a 92-degree beam and anti-glare cutoff that keeps light focused on the road without blinding oncoming traffic. Riders gain up to 180 meters of forward visibility while the tail light provides a bright 20-lumen red output visible from 100 meters.

Both lights use full-metal housings that withstand vibration and rough conditions. The headlight runs on a removable 5000mAh 21700 battery for extended runtime or easy swaps, reaching a maximum of 52 hours on low. USB-C charging restores the headlight in roughly 3.5 hours and the tail light in 1.5 hours.

Tool-free mounting hardware makes installation and transfer between bikes fast and simple. The BC28R combines powerful, well-controlled illumination with practical smart features in a durable package suited to real-world cycling.
