The Rapid X2 Kinetic is a 50-lumen, USB rechargeable safety light that mounts easily on your seatpost. A built-in accelerometer automatically switches into a constant burst mode when it senses a sudden change in speed. Similar to daytime running lights on an automobile, the Rapid X2 Kinetic helps make your presence known as a cyclist. 180 degrees of visibility allows you to be seen from varied perspectives. A Battery Auto-Save feature makes sure you’re covered the entire ride by automatically switching to a flashing mode should the battery run low.
With up to 30 hours of runtime, the Rapid X2 Kinetic ensures you’ll be drained from your ride long before your light is.
【Built-In Acceleration Sensor for Kinetic function】
Automatically turns on High for 2.5 sec when bike deceleration is detected.
