What to Compare Before Buying
Check that the intended mounting position on your bike works with one of the supplied mounting options. The listing does not give mount dimensions, so confirm fit against your seatpost or saddle setup before choosing this light.
Consider whether the five listed modes and automatic sensing behavior suit how you want to operate a rear light. The stated battery life is up to 15 hours; actual use may vary, so plan charging around your riding needs rather than treating that figure as a guaranteed runtime.
What Is Included
The listing describes two mounting kits, one for a seatpost and one for mounting beneath the saddle. It does not specify a charging cable or wall adapter as included items.
Important Limitations
IP65 is the stated protection rating; it should not be read as complete waterproofing. The listing does not provide a measured visibility distance or additional details about how the brake-sensing and vibration-sensing functions behave in different riding conditions.
