The invention provides a booster bicycle provided with a rotating disc type sensor with multiple magnetic blocks in uniform distribution, and belongs to an electric booster bicycle capable of providing booster signals by virtue of multiple-point position magnetic sensing. The sensor comprises a sensing element, a booster model processor, a digital-analog converter and an operational amplifier, wherein a plurality of permanent magnetic blocks with opposite adjacent magnetic polarities are fixedly arranged on the rotating disc of the sensing element, the rotating disc is arranged on a central shaft of a wheel of the bicycle, the hall of the sensing element is arranged on a frame close to the permanent magnetic blocks, and the operational amplifier is connected with a motor controller. The booster bicycle has the advantages that the hall can obtain square wave signals, the sensor can be used for outputting after the digital processing, a booster model can be set artificially, the booster start point, the booster finishing point, and the booster power are reasonable, so that a user and a machine can be best matched, and the power is saved.
