Fenix BC06R Rechargeable Bike Taillight Smart Safety Light Ride with confidence as the Fenix BC06R Bike Taillight conveniently signals to others for you. Designed for safety, this light features a Red CREE XP-E2 red LED with a smart brake sensing function that activates Braking mode, delivering a 90 lumen output and flashing up to 100 meters when you slow down. The light is also included with a 270° wide angle illumination feature to keep the rider visible in all directions. Accomodating Output Modes The BC06R Bike Taillight takes riding to a whole other level with its range of output modes. 8 output modes include: Spinning, Constant On, Low and High Speed Flashing, and Braking with up to 24 hours of runtime while on Low mode. With a constant cycle, spinning mode comes in handy while biking in groups to signal to others around you. Low mode comes with options of slow and fast flashing, and constant-on for continuous illumination in different biking scenarios. High mode with slow and fast flashing and constant-on are useful when signaling to traffic around you. The accomodating modes allow users to choose their desired setting based on the task at hand, and thanks to its intelligent memory, the light returns to the last setting used. Easy Operation The BC06R Bike Taillight prioritizes safety ensuring you remain seen at all times. It's also designed for user-friendliness, featuring a single-switch operation that provides immediate access to output modes. Mounting is straightforward with a quick-release structure, allowing for easy attachment and detachment to either the seat post or saddle rails. A low battery warning is indicated by a red blinking light and can be conveniently charged via USB-C through outlets or other devices.
