The Fenix BC06R smart bike taillight adds automatic safety signaling to any ride. Its built-in brake sensing function detects sudden deceleration and instantly boosts output to 90 lumens, giving following traffic and pedestrians a clear visual cue that you are slowing down.

This compact rear light delivers a wide 270° viewing angle for strong side visibility in addition to rear illumination. Multiple lighting modes, including solid and dynamic patterns, let riders choose the right output for commuting, group rides, or long-distance cycling. A built-in 560mAh battery and USB-C charging provide up to 245 hours of runtime on the lowest setting, eliminating frequent battery changes on extended outings.

The all-metal CNC-machined body feels premium and durable while the quick-release mount allows fast attachment or removal from seatposts or saddle rails. Battery level indication and one-switch operation keep daily use simple. The BC06R focuses on practical rear visibility and automatic brake signaling in a small, weather-resistant package.
