A free tool for estimating how far your electric bike will go on a single charge.
eBikeRangeCalculator.com is a free, browser-based calculator that estimates e-bike range based on the factors that matter most: battery capacity (in Wh, or calculated from Volts × Amp-hours), assist/power level, terrain, total rider and cargo weight, and wind conditions.
The site is built for e-bike owners and shoppers who want a quick, realistic sense of how far a given battery will take them — whether planning a commute, a weekend ride, or comparing batteries before buying.
The calculator starts from a baseline energy-use figure (Wh per mile) for a typical e-bike in moderate conditions, then adjusts it using multipliers for assist level, terrain, wind, and weight. See the "How This Calculator Works" section on the homepage for the full breakdown of the formula and assumptions.
All calculations happen locally in your browser. Nothing you enter — battery size, weight, or any other input — is ever transmitted to a server. See the Privacy Policy for full details.
