The present invention relates to a rear detection system for a bicycle having an ultrasonic distance sensor for rear detection. The present invention comprises: a rear object detection sensor (100) arranged in one side of a bicycle (10) behind a driver and having an ultrasonic distance sensor; and one or more emergency lamp parts (200) attached to the bicycle. When the rear object detection sensor senses an object, the detected signal is transmitted to a control part. The control part transmits the signal to the emergency lamp parts (200) to emit the emergency lamp parts (200). The present invention can safely drive in emergency situations by detecting the position of the object approaching from the rear side. The front and rear emergency lamp parts display the existence and direction of the object using light and/or sound when the object is approached within a predetermined dangerous distance. |
