E-Bike Range Estimator

Physics-based range estimate from battery Wh, assist level, rider weight, and wind/terrain factors.

WattQuick

Drivetrain + discharge losses (typical 88–95%)

Rolling + friction baseline (8–10 Wh/km)

Rider + bike + cargo

Primary result

28.9km

15.9 Wh/km consumption · 460 Wh usable

Power consumption15.9Wh/km
Usable energy460Wh
Assist multiplier1.75×
Weight penalty0.15Wh/km
Wind / terrain factor1×
Assist level3L

Note: Range = (battery Wh × pack efficiency) ÷ Wh/km. Base rolling consumption defaults to 9 Wh/km; assist scales 1.0–2.5 (levels 1–5); +0.1 Wh/km per 10 kg above 80 kg total mass; wind/terrain factor 0.8–1.5.

About E-Bike Range Estimator

Wh/km range model

Range = (Wh × efficiency) ÷ consumption. Consumption combines an 8–10 Wh/km base, assist multiplier (1→2.5), wind/terrain factor (0.8–1.5), and +0.1 Wh/km per 10 kg above 80 kg.

Planning note

Estimates are for planning rides, charging, and battery health—not a substitute for manufacturer specs or professional e-bike service.
