Voltour

Battery range

Estimate e-bike range before the climb exposes it

Voltour calculates route energy from the route itself: distance, elevation, surface, weather, assist mode, bike system, rider and luggage load, battery size, battery health, cold-weather derate, and reserve margin.

Calculate a route

More than flat Wh/km

Long climbs, gravel, headwind, cold temperatures, battery age, and high assist modes all change range. Voltour keeps those assumptions visible.

Useful for real routes

Run the calculator on an actual route, then compare usable battery, reserve, expected range band, and charging stops.

Export after checking

When the range estimate and charging plan look realistic, export GPX for your navigation app or bike computer.

Range inputs Voltour considers

  • Route distance, climbing, descent, road surface, and speed assumptions.
  • Rider weight, luggage weight, selected bike, assist mode, charger, and battery state of health.
  • Temperature, wind context, reserve margin, and route-stage requirements for longer rides.
