This control signal is transmitted to the shifting device 16, which in turn causes the shifting device 16 to automatically adjust the gear position of the transmission of the bicycle 10. The above-mentioned gear change manner may be, for example, when the rider rides an uphill section, the transmission can be adjusted to a small gear-to-large flywheel, and when riding a downhill section, the transmission can be adjusted to a large-toothed-to-small flywheel . By means of the above, an automatic shifting bicycle can be achieved, and the invention is further integrated with the mobile phone to conform to the current combination of technology and health.
總言之，本發明之自行車自動變速系統於設計上之巧思，讓自行車之騎乘者可以無需手動變換檔位，變速裝置會依據控制訊號調整自行車之變速器之檔位，或是騎乘者根據感測結果進行手動調整變速器之檔位，令不熟悉路況或是初學者也可以調整到最適合此路況之檔位以進行騎乘之動作，著實便利。 In summary, the bicycle automatic shifting system of the present invention is designed with ingenuity so that the rider of the bicycle can manually adjust the gear position of the bicycle according to the control signal, or the rider can adjust the gear position according to the control signal. According to the sensing result, the gear position of the transmission can be manually adjusted, so that the unfamiliar road condition or the beginner can also adjust the gear position most suitable for the road condition to perform the riding action, which is convenient.
