About this tool
Estimate real e-scooter range from battery Wh, rider weight, speed, gradient and traffic using road-load physics.
Real e-scooter range is battery energy divided by watt-hours per kilometre, and this calculator derives that consumption from physics rather than a single averaged number. It applies the standard road-load equation — rolling resistance (Crr × m × g × cos θ), aerodynamic drag (½ × ρ × CdA × v²) and gradient force (m × g × sin θ) — then adds the kinetic energy of ½ m v² thrown away at each stop, minus whatever regenerative braking returns, so weight, speed, hills and traffic each move the answer for a reason you can see.

Rolling, aerodynamic, gradient and stop-start energy are listed as their own lines, so you can see what to change.
Extra mass raises both rolling resistance and the energy needed for every re-acceleration — not just one of them.
Drag rises with the square of speed, so the tool shows why 60 km/h costs far more than 40 km/h rather than assuming it scales linearly.
Because claimed figures are measured at a low constant speed with a light rider and few stops. A 3 kWh scooter uses about 15 Wh/km at a steady 25 km/h but around 37 Wh/km at 45 km/h in city traffic — which turns roughly 180 km of claimed range into roughly 74 km of real range on the same battery.
Less than most people expect on flat roads and a lot on hills. Mass drives rolling resistance and re-acceleration energy but not aerodynamic drag, so an extra 70 kg of pillion and luggage on flat city roads cuts range by roughly 15–20%; on a 6% climb the same load can halve it, because gradient force is directly proportional to mass.
Up to a point, yes — drag falls with the square of speed, so halving your cruising speed cuts aerodynamic losses to a quarter. Very low speeds stop helping because rolling resistance and the controller's own draw do not shrink, and the trip takes longer, which increases total idle consumption.
Plan on about 90% of the nameplate figure. The battery management system holds a reserve at the bottom of the pack, and most riders recharge before zero anyway. Multiply that again by state of health: an 85% SoH pack on a 3000 Wh nameplate gives about 2,295 usable watt-hours.
