The invention discloses a bicycle automatic speed changing system which is characterized in that a wireless pedal sensor capable of identifying the pedal direction and the pedal frequency is mounted on a bicycle pedal middle shaft, a wireless rear derailleur capable of electrically derailleur and a wireless front derailleur at a chain wheel are mounted on a flywheel, the wireless rear derailleur is used as a main control unit, and the wireless front derailleur is used as a wireless front derailleur. The main control MCU receives pedal signals and bicycle speed information through a built-in wireless communication module, after comprehensive analysis and calculation, the chain wheel of which gear is adopted to drive the bicycle to advance is decided, and the system can be freely combined from simple configuration to advanced intelligent configuration so as to meet individual requirements of different bicycles and different riders. By means of the automatic speed changing device, manual speed changing of the bicycle is changed into automatic speed changing, a rider can more concentrate on riding and does not need to be distracted to frequently adjust gears of a flywheel and a chain wheel, energy and physical power consumption of the rider is reduced, and more fun is brought to riding.

    本发明公开了一种自行车自动变速系统,在自行车脚踏中轴上安装能识别脚踏方向和脚踏频率的无线脚踏传感器、在飞轮上安装有可进行电动拨链的无线后拨链器和牙盘处的无线前拨链器,无线后拨链器作为主控单元,主控MCU通过内置的无线通信模组接收脚踏信号、车速信息,综合分析计算后决定采用那一档链轮来驱动自行车前进,本系统可以对系统从简单配置到高级智慧配置进行自由组合,以匹配不同车辆及不同骑行人士的个性化需求,实现了从自行车手动变速到自动变速的转变,使骑行者可以更加专注于骑行,不必分心去频繁地调整飞轮和牙盘档位,减少骑行者的精力和体力消耗,给骑行带来更多的乐趣。
