The invention discloses a booster bicycle provided with a sensor with multiple magnetic blocks in nonuniform distribution in a shell, and belongs to an electric booster bicycle capable of providing booster signals by multi-point position magnetic sensing. The sensor comprises a sensing element, a booster model processor, a digital-analog converter and an operational amplifier which are connected in sequence, the sensing element comprises a rotating disc, a fixed disc, permanent magnetic blocks and a hall, wherein the permanent magnetic blocks and the hall are arranged in an internal hollow space formed by the embedding of the rotating disc and the fixed disc, a plurality of permanent magnetic blocks are arranged on the rotating disc, the magnetic polarities of the adjacent permanent magnetic blocks are opposite and are different in distance, and the hall on the fixed disc is arranged at the position close to the permanent magnetic blocks. The sensor is arranged on a central shaft of a wheel of the bicycle, and the operational amplifier is connected with a motor controller. The booster bicycle has the advantages that the permanent magnetic blocks and the hall are relatively fixed, the hall can obtain rectangular wave signals, the sensor can be used for outputting after the digital processing, a booster model is 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.
