Interaction: Hover over or tap a chart to inspect data at different speeds — all panels follow along. Click to lock a speed. The vertical line shows the selected point or the equilibrium speed.

Physics model: Three regions: phase current limited (I_fas = limit), battery current limited (I_batt = limit, solves R×I²+V_bemf×I=I_batt×V), and voltage limited (D=100%, I drops linearly).

Disclaimer: The simulator is based on a simplified physics model, and all results are theoretical estimates. Actual performance, range, consumption, and other values depend on many factors and may deviate from what is shown here. The values are provided for guidance only, without any guarantee of accuracy, and GBIKE accepts no liability for decisions made based on the simulator's results. Always verify that your vehicle complies with applicable laws and regulations.
