E-Bike Range Calculator

Estimate how far an e-bike can go on a charge.

How the Math Works

The E-Bike Range Calculator uses a straightforward division formula: range equals battery capacity divided by energy consumption. Battery capacity (measured in watt-hours, Wh) represents the total energy stored in the e-bike's battery, while consumption (typically expressed in Wh per mile or Wh per kilometer) indicates how much energy is used per unit distance. By dividing these values, the calculator determines how many miles or kilometers the e-bike can travel on a full charge. This formula assumes consistent riding conditions and energy efficiency, providing an idealized estimate based on the bike's electrical requirements.

Practical Applications

To use the calculator, first determine your e-bike's battery capacity by checking the manufacturer's specifications or labeling on the battery pack. Next, calculate your average energy consumption by tracking battery usage over several rides—divide the battery's watt-hour capacity by the distance traveled during each trip. Input these values into the calculator to determine your expected range. You can also adjust for variables like terrain, rider weight, or assist level by modifying your consumption estimate, as hillier routes or higher assist settings typically increase energy usage per mile.

Day-to-Day Use

This calculation helps e-bike riders plan trips confidently, ensuring they don't run out of power mid-journey. By knowing your range, you can optimize routes, pack spare batteries for longer excursions, or choose appropriate assist levels for daily commutes. It also aids in comparing different e-bike models or upgrading batteries, as understanding consumption patterns reveals which options best meet your riding needs. Additionally, accurate range estimates reduce range anxiety and help budget for charging infrastructure or battery replacement costs over time.

Worked example

500 Wh ÷ 12 Wh/km → ~42 km.
