Features:
The built-in high-precision sensor, combined with depth algorithm, can detect the tail lamp quickly even if the brake is slight.
According to the different horizontal angles of the seat tube, it will automatically calibrate the depth algorithm to identify the uphill and downhill sections, and maintain the braking accuracy at all times.
One key switch between manual mode and intelligent mode.
It can be used to filter the small rolling motion and small bumpy road section. But too large a hole to slow down the shock zone will still active the brake light warning.
Ride fearlessly whether it is rainy or sunny.
