⚡ E-Bike Range Calculator
Estimate how far your e-bike goes on one charge — from battery size, assist level, rider weight and terrain.
Your setup
Quick examples
How the estimate works
- Range = battery Wh × usable % ÷ consumption (Wh/km).
- Consumption presets are grounded in published data: real-world tests put Eco at 6–9 Wh/km, touring at 9–14 Wh/km and turbo/throttle at 15–25+ Wh/km (Himiway range guide); an Electrek-verified real-world ride measured 6.9 Wh/km in slow pedal-assist; Trek's 800 Wh eco claim implies ~7.6 Wh/km.
- Rider weight: ±7% consumption per 10 kg from a 75 kg baseline (rolling-resistance share of total drag).
- Climbing: E = m × g × h ÷ 3600 ÷ 0.75 motor efficiency, in Wh per km.
- Cold weather raises consumption ~15–25% (industry guidance), which works out to roughly 13–20% less range.
Disclaimer: this is an estimate — real range varies with wind, tires, temperature, battery age and pedaling effort.
FAQ
How far can a 500 Wh e-bike go?
On Eco mode at about 7 Wh/km, a 500 Wh battery gives roughly 64.3 km of usable range (500 Wh × 90% ÷ 7 Wh/km). On Turbo at 20 Wh/km the same battery gives about 22.5 km.
What is a normal e-bike consumption in Wh/km?
Typical real-world consumption is 5–20 Wh/km: Eco 6–9, touring 9–14, sport around 14 and turbo 15–25+ Wh/km, depending on assist level, weight and terrain.
Does rider weight affect e-bike range?
Yes. As a rule of thumb, every 10 kg above a 75 kg baseline raises consumption by about 7% — so a 95 kg rider gets roughly 56.4 km where a 75 kg rider gets 64.3 km from the same 500 Wh battery in Eco.
How do hills change the range?
Climbing 100 m per 10 km costs about 3.6 Wh/km extra for a 100 kg bike+rider system — dropping a 500 Wh Eco estimate from 64.3 km to about 42.3 km.
Does cold weather reduce e-bike range?
Yes — below about 5°C expect roughly 13% less range, and up to 20% less in freezing conditions, because lithium cells deliver less usable energy when cold.
