⚠️ Real-world range varies. Always carry enough charge for your return trip plus 20% reserve. Factors like stop-and-go riding, headwinds, and steep climbs can significantly reduce range.

📊 How We Calculate

Our calculator uses real-world data from thousands of e-bike trips. Base consumption starts at ~15 Wh/mile for a typical rider on flat ground, then adjusts for your specific variables:

Core Formula: Wh/mile = Watts ÷ Speed
Example: 7,500W at 40 mph = 187.5 Wh/mile
Weight: +3% per 25 lbs over 200 lbs
Elevation: ~10 Wh per 100 ft of climbing
Temperature: Li-ion loses ~1% per °F below 68°F, steeper below 40°F
Air Resistance: Power needed scales with speed² above 20 mph

✓ Calibrated with real-world data from high-performance builds (72V 50Ah @ 55 mph verified)

We provide a conservative estimate (shown large) and an optimistic estimate for ideal conditions. Plan your rides using the conservative number.
