Abstract

This invention provides a data measurement method for electric-assisted bicycles, which accurately measures and records voltage, current, and power data using voltage, current, and power sensors. This data is collected by a sensor module and processed and analyzed by an imager to calculate real-time power values ​​and assistance ratios. This data not only reflects the operating status of the electric assistance system but can also be used to dynamically adjust the assistance mode for optimal riding performance. Power calculation helps monitor the load on the motor and battery, ensuring the most suitable power support is provided under different riding conditions. Through timely analysis and feedback of this data, this invention achieves the goal of improving the performance of electric-assisted bicycles and enhancing rider comfort.
