A warning system for a bicycle comprising front 10 and rear side 20 proximity sensors, a front side warning apparatus 14, a first vibration motor 24, and front side 12 and rear side processors 22. Front side proximity sensor 10 generates a detection signal when an object is detected within a specified range on the front side, and the front side processor 12 then sends a signal to activate the front side warning apparatus 14. Similarly, rear side proximity sensor 20 generates a rear side detection signal when an object is detected within a specified range on the rear side, and the first vibration motor 24 is operated in response to a signal from the rear side processor 22. The system may also include a speed sensor, an inertial sensor, environment (i.e. temperature, humidity) sensors, an altitude sensor and/or a GPS sensor. The range of the proximity sensors may be adjusted based upon the speed of the bicycle, and the vibration motor may be configured to vibrate at a set one of a plurality of different frequencies depending upon how close a detected object is. The front warning apparatus 14 may be a second vibration motor.
