Real-world e-bike range calculator
Brochure range assumes perfect conditions. Tell us how you actually ride and we’ll give you a realistic band — and show what affects it most.
How we estimate
We start from about 10 Wh per km for a 75 kg load on flat ground at 20 km/h（a medium assistance mode, then adjust for each factor. Cold weather reduces the energy a lithium-ion battery can deliver; we keep 5% in reserve. These are typical figures from how e-bikes behave, not a specific maker’s data — for your model, the maker’s own range tool may be more precise.）
