Electric Scooter RPM at 20 km/h
For a standard electric scooter or bike (with 14–16 inch outer tire diameter), the motor speed at 20 km/h is typically between 250 and 300 RPM.
Core Calculation Formula:
$$RPM = \frac{Speed (km/h) \times 16.67}{Tire Circumference (meters)}$$
Common Tire Size Reference:
| Tire Outer Diameter | Circumference | RPM at 20 km/h | Typical Vehicle |
|---|---|---|---|
| 14 inch | ~1.12 m | ~298 RPM | Compact E-bikes |
| 16 inch | ~1.28 m | ~260 RPM | Standard Scooters |
