EV Scooter Range Calculator
Plan a riding-energy and charge window from your own battery and consumption evidence. Example inputs are visible assumptions, with no automatic rider-weight, weather or battery-age coefficients.
Sources checked 9 October 2026. Example inputs are scenarios; use your own bill, equipment or trip measurements.
Your inputs
The default is an illustrative input, not a manufacturer specification. Nominal pack-label Wh can exceed energy accessible in use.
Use measurements from comparable rides. The default is a worked-example assumption; the tool does not infer this rate from assist mode, rider weight or weather.
Include the return journey if there is no planned recharge.
Your calculation
Use a riding measurement instead of a universal multiplier
Distance budget = usable full-charge Wh × (start − reserve) ÷ 100 ÷ battery Wh/mile
This is an energy-budget calculation. It assumes the usable state-of-charge percentage is approximately proportional to battery energy and that consumption remains similar to the sample you enter. A few display bars or nominal voltage readings do not establish a precise energy measurement. Results are scenarios and are not an assurance that a particular ride is achievable.
If a display reports reliable battery energy, divide the energy used by the ride distance. With only a reasonably informative percentage gauge and a usable-energy estimate, 20 miles using 40% of a 500 Wh usable pack implies about 10 Wh/mile: 500 × 0.40 ÷ 20. This is a worked example. Use several similar rides; do not deliberately run the battery to empty to obtain a measurement. A wall charging meter measures charger-input energy and can include losses, so it should not be substituted directly for battery energy used.
Read the conditions behind a scooter range claim
The Segway MAX G3 manual lists separate range figures for its speed modes and describes controlled load, temperature, speed and pavement conditions for those measurements. A marketed range obtained at a steady test speed does not necessarily describe a stop-and-start commute. Check the specific product and market manual before using a claim as a planning baseline.
Record a consumption sample at your ordinary riding speed and with your actual load. Keep a separate sample for a route with sustained climbs. The calculator applies no fixed extra energy for each pound of rider weight and no common Eco, Normal or Sport speed: those settings vary between scooter models.
A larger battery label does not authorize a heavier rider, steeper incline or higher speed. Follow the model’s own load and riding limits. For distance planning, include the whole return ride unless a compatible charger will be available between legs. If the charge indicator is only a few bars, the percentage calculation is too coarse to establish a precise arrival reserve.
Worked scooter charge window
For an illustrative 450 Wh usable pack and 18 Wh/mile consumption, an 80% departure and 10% reserve provide 315 Wh, or 17.5 miles. A 20-mile ride uses 360 Wh and ends at an estimated 0% charge. It exceeds the selected reserve budget by 2.5 miles. Change the route or charging plan rather than treating the advertised full-charge range as a guaranteed commuting distance.
Battery and charging instructions remain model-specific
CPSC guidance says to use the supplied charger, an approved replacement battery and the manufacturer’s charging instructions, and to remain present while charging. A matching plug or an energy calculation does not establish charger or range-extender compatibility. Check the exact product for applicable recall or safety notices.
Use the manufacturer’s storage and charging-temperature guidance for the battery you own. This tool adds no universal annual degradation curve, charging-temperature rule or lifespan promise. If a pack’s usable capacity has changed, use appropriate measured evidence or manufacturer diagnostics instead of inferring a fixed loss from its age.
Questions and answers
Are the default battery and consumption figures tested product ratings?
No. They are illustrative example inputs. Enter usable-energy and consumption evidence for your own vehicle and comparable riding conditions.
Does the tool automatically adjust for weight, weather or riding mode?
No. Those influences should be reflected in a comparable consumption measurement. The calculator adds no universal weight, temperature, terrain or mode multiplier.
Can I use nominal volts times amp-hours as usable battery energy?
Nominal voltage times amp-hours estimates nominal pack watt-hours. Accessible energy can differ because of battery management, condition and temperature; do not label a nominal figure as a verified usable measurement.
