Real range calculator

Range is just battery capacity divided by how much energy you use per mile. This calculator makes that arithmetic explicit and lets you set the consumption figure yourself, instead of hiding it behind a single optimistic number.

Where the numbers come from. The baseline of 15 Wh/mi is a starting point you can change, not a measurement — it's roughly what a mid-weight rider on a mid-assist setting uses on rolling ground. The multipliers are engineering rules of thumb: heavier riders, steeper ground and higher assist all pull more current. This is a model, not data. The real numbers live in the Real Range Database, and they come from riders. If you own one of these bikes, tell us what you actually get — that's what turns this page from arithmetic into evidence.
