Hoverboard, Scooter & EUC Calculators
Free, practical tools for personal electric transport — estimate your range, time a charge, gauge top speed, plan battery life, check your weight against a board’s limit, and convert between speed units.
Range Calculator
Estimate how far your board or scooter goes on a charge from its battery voltage and capacity, scaled by rider weight and terrain.
Charge Time Calculator
Work out how long a full charge takes from your battery's amp-hours and your charger's output current, allowing for efficiency.
Top Speed Estimator
Estimate a device's theoretical top speed from wheel diameter and motor RPM — or derive RPM from the motor's kV and voltage.
Battery Cycle Life Calculator
See how many years a pack lasts before it fades to ~80% capacity from its rated cycles and how often you charge, plus capacity left today.
Weight Capacity Checker
Check your weight against a board's max-load rating and see how much headroom you have before the recommended limit.
Speed Converter
Convert riding speed between km/h, mph, and m/s, and turn wheel RPM into road speed for any wheel diameter.
