How Far Can an E-Bike Really Go? Range, Explained
How-To · Commuter
That "up to 68 miles" on the spec sheet isn't a lie — but it isn't your Tuesday, either. Here's how e-bike range actually works, so no number ever surprises you again.
Every e-bike range number you've ever seen is a best-case number: lightest rider, lowest assist, flat ground, no wind, perfect weather, fresh battery. It's the highway-mileage of e-bikes — real, but earned under lab conditions.
For normal mixed riding, plan on 60–70% of the claimed max. If you ride throttle-only or live on hills, plan on closer to 40–50%. So a bike rated "up to 68 miles" is a comfortable 40–48 miles in the real world — and still a 65-mile machine if you pedal and keep it in eco. That's not a downgrade. That's how to trust the number.
The one equation that explains everything
Range comes down to a single idea: how many watt-hours (Wh) of battery you have, divided by how many watt-hours each mile costs you.
What you have: Volts × Amp-hours = Wh. A 48V × 20Ah commuter battery holds 960 Wh in the tank. What each mile costs: anywhere from ~14 Wh/mi (eco, pedaling, flat) to ~30 Wh/mi (throttle, hills, headwind, cold). Same battery, very different days:
The 6 things quietly eating your range
If your real-world miles fall short of the box, one of these six is almost always why:
- Throttle vs. pedal-assist. Throttle-only is the single biggest drain — you're asking the motor to do 100% of the work. Pedal-assist (PAS) stretches the same battery 30–50% further.
- Assist level. Level 5 feels great and empties the tank. Dropping to 2–3 on flats is the easiest range you'll ever find.
- Weight — rider + cargo. More mass means more watt-hours per mile, especially from every stop.
- Hills and headwind. Climbing and fighting wind are where the motor gulps power — a flat and a hilly commute can differ by 40%.
- Tire pressure. Fat tires at low PSI feel plush but roll slow. Keep them near the top of the printed range for distance days.
- Cold. Lithium batteries lose 10–30% of usable range in the cold. It comes back when it warms up.
Save this: the Real-World Range Cheat-Sheet
Based on a ~960 Wh battery. Scale up or down for your own pack (Volts × Amp-hours). First, what a mile actually costs by riding style — and the honest range each one buys you:
| Riding style | Rough cost | Est. real range |
|---|---|---|
| Eco — pedaling, flat, level 1–2 | ~14 Wh/mi | 65+ mi |
| Mixed — normal PAS, some stops/hills | ~20 Wh/mi | ~48 mi |
| Throttle-heavy — hills, headwind, cold | ~30 Wh/mi | ~32 mi |
And the six range thieves with the quick fix for each:
| Range thief | What it costs | Quick fix |
|---|---|---|
| Throttle-only riding | −30 to −50% | Use pedal-assist; save throttle for hills |
| Max assist (level 5) | Big drain on flats | Drop to level 2–3 when you don't need the push |
| Extra weight / cargo | More Wh every mile | Lose the dead weight on long days |
| Hills & headwind | Up to −40% | Plan flatter routes; lower assist downhill |
| Low tire pressure | Steady drag | Inflate near the max printed PSI for distance |
| Cold weather | −10 to −30% | Store the battery indoors; let it warm up first |
Forget the max number. Do your number: weekly miles ÷ real-world range = how often you plug in. A 5-mile commute, five days a week, is 50 miles — about one charge a week on a 960 Wh bike, with room to spare. Shop range that way: not "what's the biggest number," but "does one charge cover my week?"
The bike behind the math: Kommoda 3.0
We used the Cyrusher Kommoda 3.0 for these numbers because it's a textbook commuter battery: 48V 20Ah (960 Wh), a 750W motor, a step-through frame, and a real-world ~48 miles that covers a full work week on one charge — for $1,499, rated up to 68 miles when you pedal and keep it sensible. And when you're spending four figures online, it ships with a full manufacturer warranty, free shipping, a 30-day return window, and real people on chat. You're not on your own after checkout.
