Electric

E-Bikes

The motor is the easy part. What decides your purchase is the battery, the class, and what the thing actually costs to run — so that's what we compute.

What you’re actually deciding

Almost every e-bike buyer starts by comparing motor wattage, which is the least useful number on the spec sheet. Peak wattage is a marketing figure measured for a few seconds under ideal conditions, and two bikes claiming “1000W peak” can behave completely differently. The numbers that decide your experience are the battery capacity in watt-hours, the motor position (hub or mid-drive), and the legal class, which determines where you’re allowed to ride it.

Watt-hours are the honest capacity figure: volts × amp-hours. A 48V 13Ah pack is 624Wh, and that single number tells you more about range than any manufacturer’s claimed mileage — because the claimed mileage was measured by the manufacturer, on the lowest assist level, by a light rider, on flat ground, in good weather. Treat claimed range as the ceiling of physics, not a forecast of your commute.

The thing nobody tells you about Amazon and e-bikes

The brands you’ve heard of — Specialized, Trek, Rad Power, Lectric, Aventon — largely don’t sell e-bikes on Amazon. They sell direct, or through dealers. What Amazon actually stocks is a different, less famous set of brands, and most published “best e-bike” lists quietly ignore that gap because their affiliate links point somewhere else.

We link Amazon, so we’re telling you plainly: this hub covers what Amazon sells. If the right bike for you is a Lectric, buy a Lectric — we just can’t earn from saying so, which is exactly why we’re saying it. What Amazon does offer in return is a returns process that actually works on a 60lb object, which is worth more than it sounds when the alternative is arguing with a direct-to-consumer brand about a damaged pallet.

What we can and can’t tell you

We haven’t ridden any of these bikes, so we won’t tell you how they feel. What we can do is read every listing’s published specs, tell you which claims are the seller’s rather than facts, and compute the one thing nobody else publishes: what an e-bike actually costs to run, with the electricity rate, its source, and the arithmetic all shown.

Heads up: we earn a commission if you buy through the links on this page, at no extra cost to you. It never decides what makes the list — here’s how that works.

What to buy

Our picks, with the live price on the card. No need to click through unless you want the reasoning — and you should want the reasoning.

The number that matters

The cost-per-charge shortcut.Battery watt-hours ÷ 1000 × your electricity rate = the cost of a full charge. At the US average residential rate of 18.83¢ per kWh (EIA, April 2026), a 624Wh pack costs about 11.7¢ to fill. Not per week — per charge. That is the entire running cost of an e-bike, and it is small enough that it almost never belongs in your buying decision.

Which means the real cost of an e-bike is the purchase price, the battery’s eventual replacement, and whether it gets stolen. We work all of that through in e-bike cost to run.

Common questions

How much does it cost to charge an e-bike?

Pennies. Divide the battery’s watt-hours by 1000 and multiply by your electricity rate: a 624Wh pack at the US average of 18.83¢/kWh is about 11.7¢ per full charge. The full arithmetic, with sources, is in e-bike cost to run.

Why aren't Rad Power, Lectric or Specialized in your roundups?

Because they don’t sell those bikes on Amazon, and Amazon is the only retailer we have an affiliate relationship with. Rather than pretend those brands don’t exist, we’re telling you: they’re worth considering and you’ll have to buy them direct. See the best e-bikes on Amazon for what that trade-off actually costs you.

Is a hub motor or a mid-drive better?

Neither — they’re different tools. Hub motors are cheaper, simpler and fine on flat ground; mid-drives use your gears, so they climb far better and wear your chain far faster. Most Amazon e-bikes are hub-drive. The full comparison is here.

Can I trust the claimed range on an e-bike listing?

As a physical ceiling, yes. As a prediction of your ride, no. Claimed ranges are measured on the lowest assist setting, by a light rider, on flat ground, with no wind. Hills, cold weather, throttle use and your own weight all cut it, sometimes by half. Watt-hours are the honest number — here’s why.

What e-bike class am I allowed to ride?

It depends on your state and often your local park authority. Class 1 (pedal assist to 20mph) is allowed almost everywhere bikes are; Class 3 (assist to 28mph) is frequently barred from multi-use paths. Check before you buy, not after — the classes explained.
