This research analyzes the impact of input parameters on the performance of electric motorcycles, utilizing a simulation model that comprises both a dynamic model and a battery model. The study focuses on investigating the effects of transmission ratio and wheel radius. Simulation results show that increasing the transmission ratio from 2.66 to 4.94 leads to an decrease in speed and distance traveled, while electricity consumption increases by 0.16%. Similarly, increasing the wheel radius from 0.1 m to 0.25 m results in a higher maximum speed and travel distance but with decreased battery voltage and increased engine power consumption. These results suggest that altering the transmission ratio and wheel radius can enhance the efficiency and dynamics of electric motorcycles. The research highlights the usefulness of utilizing MATLAB SIMULINK software and mathematical models in the field of electric motorcycles and their practical applications.
