E-bike range claims are everywhere and rarely comparable. One brand says “up to 80 miles”, another “est. 25–65 miles”, and a third “60–90 miles” for a battery of similar size. The differences come mostly from test conditions, not from the bikes.
The good news: you can make your own estimate from one number every brand publishes, or lets you calculate: battery capacity in watt-hours.
Watt-hours: the size of the tank
Watt-hours (Wh) measures how much energy a battery stores. It equals volts × amp-hours. A 48V, 15Ah battery stores about 720Wh. When a brand gives only volts and amp-hours, we multiply them on this site and mark the result “≈”, as with the Himiway D5 2.0 (≈ 720Wh).
Estimating your range
Energy use per mile varies with how you ride. As a rough guide for a typical rider on mixed terrain:
| Riding style | Approx. Wh per mile | 500Wh battery | 720Wh battery | 960Wh battery |
|---|---|---|---|---|
| Low assist, flat, steady pedaling | 12–15 | 33–42 mi | 48–60 mi | 64–80 mi |
| Moderate assist, mixed terrain | 18–25 | 20–28 mi | 29–40 mi | 38–53 mi |
| High assist or throttle, hills, heavier rider | 28–40 | 12–18 mi | 18–26 mi | 24–34 mi |
These are estimates, not test results. Your own riding will land somewhere in the table depending on the factors below. After a few rides, your bike’s display or app will tell you more than any formula.
What drains a battery fastest
- Assist level and throttle. The biggest factor. Throttle-only riding uses far more energy than steady pedaling with low assist.
- Speed. Air resistance grows with the square of speed, so 28 mph uses much more energy per mile than 18 mph.
- Total weight. Rider plus cargo plus bike. Heavier loads need more energy, especially on climbs.
- Hills. Climbing takes a lot of energy, and you only recover a little descending.
- Tires. Fat, knobby or under-inflated tires roll harder.
- Temperature. Lithium batteries deliver noticeably less energy in the cold.
- Stop-and-go riding. Accelerating from every light takes energy.
- Wind. A headwind acts like a hill.
Why brand claims differ
Brands choose their own test conditions: rider weight, assist level, speed, terrain, temperature. Some describe them, many don’t. The Vanpowers GrandTeton Pro claims Up to 93 mi (test conditions stated) from 705.6Wh, while the Velotric Nomad 2 claims Up to 65 mi from 705.6Wh. Same battery size, very different claims. That’s why our rankings use watt-hours. See best long-range e-bikes.
Range over the battery’s life
Lithium-ion batteries lose capacity gradually with charge cycles and age. A battery that delivers 40 miles when new will deliver less after several years of regular use. Storing it partly charged at room temperature and avoiding deep discharges slows the decline. See battery care.
How much range do you need?
Take your longest regular ride, double it if it’s a one-way commute, then add 30–50% for cold, wind and battery aging. If that number is far beyond what one battery covers, look at bigger batteries, dual-battery bikes or charging at work.
Worked example
Say you commute 9 miles each way on the Lectric XPress2 (672Wh), with a few moderate hills, at medium assist. At about 22 Wh per mile, the round trip uses roughly 400Wh, leaving a healthy margin. In January, with cold reducing usable capacity and a headwind home, the same trip might use 25–30% more, around 500Wh: still inside the battery, but closer to empty. That’s why we suggest sizing the battery at 1.5× your typical daily use.
Compare the Aventon Soltera 2.5 (345.6Wh). The same 18-mile round trip would use most or all of its battery in winter, so you’d need to charge at work. For a 4-mile commute, though, it would last several days between charges.

Frequently asked questions
How many miles does an e-bike battery last on one charge?
It depends on battery size and riding. A 720Wh battery gives roughly 29–40 miles at moderate assist for many riders, more on low assist and less with throttle, hills or cold.
How do I calculate e-bike range?
Divide battery watt-hours by your estimated watt-hours per mile. 15 Wh/mile for gentle riding, 20–25 for moderate, 30–40 for throttle-heavy riding with hills.
Does a bigger battery make an e-bike heavier?
Yes. More cells add weight, typically a few pounds for each extra few hundred watt-hours.
