How Top Speed is Calculated
This calculator uses the following formula to estimate the top speed of your electric scooter:
Top Speed (km/h) = sqrt((2 * Motor Power (W) * Efficiency) / (Air Density * Frontal Area (m²) * Drag Coefficient (Cd) + (Rider Weight (kg) + Scooter Weight (kg)) * g * Rolling Resistance Coefficient (Cr)))
Where:
- Motor Power (W): The power output of the motor in watts.
- Battery Voltage (V): The electric potential provided by the battery.
- Rider Weight (kg): The weight of the rider.
- Scooter Weight (kg): The weight of the scooter.
- Drag Coefficient (Cd): The drag coefficient of the scooter.
- Frontal Area (m²): The frontal area of the scooter in square meters.
- Rolling Resistance Coefficient (Cr): The rolling resistance coefficient of the tires.
- Air Density: Assumed to be 1.225 kg/m³ at sea level.
- g: Gravitational acceleration, approximately 9.81 m/s².
- Efficiency: Assumed to be 0.9 (90%).
