【Overwhelming Brightness and Flexible Lighting Modes】Equipped with a high-intensity 1000-lumen LED, achieving a maximum illumination distance of 300m. The 180° wide-angle illumination provides a wider range of light compared to normal, making it easier to see the road ahead, as well as oncoming vehicles and pedestrians on both sides. It ensures a clear view even on dark roads. Furthermore, it features five lighting modes: sensor automatic mode, high mode, middle mode, eco mode, and SOS flashing mode, catering to diverse lighting needs and adjustable according to road conditions and scenes. It protects you from accidents on night roads, making it useful for commuting to work or school by bicycle, cycling, outdoor activities, and various other scenarios. 【Newly Developed Light Sensor & Automatic Lighting Switch】Automatically adjusts the brightness of the light according to the surrounding brightness. It becomes brighter as the surroundings get darker, ensuring safety during night riding. It also features a function to automatically turn off the light in bright environments to conserve battery power. This allows for worry-free use over extended periods. ※ Operation explanation of smart light sensor mode: During normal riding (light sensor mode ON) → Entering a tunnel/dark place (automatically activates lighting mode) → Returning to a bright environment (automatically deactivates lighting mode). 【Easy Installation, High-Strength Body, and IPX6 Waterproof】Securely fits and firmly fixes to handlebars of any thickness, regardless of the bicycle type, using a tool-free mounting bracket. Suitable for handlebars (diameter 19-28mm) of all bicycles, including road bikes, cross bikes, and mountain bikes. It can withstand vibrations from bumps and will not easily fall off even with impacts from rough roads. The lightweight ABS resin body is impact-resistant and boasts durability to withstand drops and shocks. The IPX6 waterproof rating is reliable in rainy weather, allowing you to ride without worry even in sudden rain, making it a bicycle light that can be used in bad weather. 【Type-C Fast Charging & Remaining Battery Display】Fully charges the battery in just 5 hours with Type-C fast charging, allowing for up to 20 hours of use. The LED power indicator allows you to check the riding time in real-time, eliminating concerns about remaining distance. The battery level is displayed on the LCD screen, making it easy to see at a glance and understand when to charge, so you don't have to worry about the battery running out suddenly while riding. In addition to bicycles, it can also be used as a flashlight in various situations such as camping, mountain climbing, night fishing, night walks, power outages, and emergencies.
