1. A bicycle safety system, comprising:
a radar for detecting a signal of one or more vehicles in a left blind spot and a right blind spot behind a bicycle;
a controller for receiving the signal from the radar and determining whether to issue a warning based on the signal; and
a warning apparatus, comprising;
a tube;
a vibrating motor comprising a rotary shaft and an eccentric block connected to the rotary shaft, wherein the rotary shaft and the eccentric block are arranged inside the tube; and
an impact sounder comprising an elastic member and an impact block, wherein the elastic member comprises a first end fixed to an inner wall of the tube and a second end connected to the impact block;
wherein the controller outputs a control signal to drive the rotary shaft to rotate if the warning is needed to issue, the rotation of the rotary shaft drives the eccentric block to rotate and result in vibration, and the eccentric block hits the impact sounder, causing the impact block to hit the inner wall and thus create an impact force and emit a sound.
