Why does cold reduce e-bike range?

Cold temperatures lower usable battery capacity. The calculator applies a temperature derate so winter estimates are realistic.

Ebike Range Calculator

Q: What affects e-bike range the most?

Speed, hills, wind, total weight, tire type/pressure, temperature, and how much you pedal have the largest impact on range.

Q: How do I estimate range for my commute?

Enter battery voltage and amp-hours, rider and bike weight, average speed, and choose terrain, wind, tire, posture, and pedaling. The calculator outputs miles or kilometers and a sensitivity band.

Get a real-world range estimate of your range.

Estimate real-world range based on your battery, weight, speed, terrain, wind, and riding style. Switch units, tweak assumptions, and share a link to your exact setup.

Range FAQs

What affects e-bike range the most?

Speed, hills, wind, rider & bike weight, tire type/pressure, temperature, and how much you pedal.

How do I estimate range for my commute?

Enter your battery V/Ah, your weight, average speed, choose terrain & wind, and the tool will estimate miles for your setup.

Why does cold weather reduce range?

Battery chemistry delivers fewer watt-hours in the cold; we apply a temperature derate to reflect real-world performance.
