The Science Behind Range

Electric scooters vary widely in battery capacity and motor efficiency. Understanding how far you can ride helps you plan commutes and avoids range anxiety. Battery capacity, measured in watt-hours, represents how much energy the pack stores. The motor power draw combined with your average speed determines energy use per mile. Environmental factors like hills and wind can alter results, but this calculator provides a practical baseline.

Key Formula

The estimated distance in miles is calculated using:

$C$ is battery capacity in watt-hours, $P$ is motor power in watts, and $S$ is average speed in miles per hour. The fraction estimates hours of operation, which is then multiplied by speed to get range.

Realistic Expectations

Manufacturers often list maximum range under ideal conditions—flat ground, low speed, and a lightweight rider. In daily use, expect a bit less. Higher speeds and frequent acceleration draw more power. Cold temperatures can also reduce battery performance. Still, a quick calculation can help you decide whether you need to recharge before heading home.

Example Scenario

Battery	Motor	Speed	Estimated Range
400 Wh	350 W	15 mph	17 miles

This example assumes constant speed on relatively flat terrain. Longer hills or stop-and-go traffic will lower the range, so plan for a buffer when exploring new routes.

Extend Your Battery Life

Maintain tire pressure, avoid carrying unnecessary weight, and keep your scooter out of extreme heat or cold to preserve battery health. Regenerative braking, if available, can slightly increase range in hilly areas.
