摘要： An adaptable bicycle shifter making use of a torque computation algorithm based on the classical law of conservation of energy and employing a global positioning system (GPS) altimeter for sensing a road inclination, an accelerometer for sensing a bicycle acceleration and a hot wire anemometer for sensing a wind load, serving to automatically attenuate or appreciate programmed shifting speeds in real time to maintain rider standard shifting torques thereof. Adaptable bicycle shifter is additionally provided with capability to sense, record, and interpret rider automatic shift override commands and further adjust automatic shift criteria to rider ongoing preference.
