How the Calculator Works

The ESK8 calculator takes three inputs: Motor KV rating, Battery Voltage, and Motor Gear Ratio. By inputting these values, you’ll obtain a precise speed estimation for your electric skateboard. This calculator operates on a fundamental ESK8 speed formula and provides results in an easy-to-understand manner.

Understanding the ESK8 Speed Formula

The formula used in the ESK8 calculator is as follows:

Speed (mph) = Motor KV rating * Battery Voltage * Motor Gear Ratio * 0.10472

Here, the Motor KV rating indicates the motor’s speed constant provided by the manufacturer. The Battery Voltage refers to the voltage of the battery pack used in the ESK8. Finally, the Motor Gear Ratio represents the ratio between the motor gear’s teeth and the wheel gear’s teeth.
