“Advertised e-bike range is inflated” is said everywhere and proven nowhere — in one citable place, per listing, with the work shown. This page is that place.
Below is the Range Reality Index v1.0: 25 budget e-bike listings, each with its claimed range and battery capacity taken from public sources on October 4, 2026, checked against physics using our published methodology. Every row shows its work. The headline finding, stated plainly: not one of the 25 headline claims survives contact with physics at typical consumption. Five claims are physically implausible for real riding; the other seventeen achievable ones require ideal conditions (light rider, lowest assist, flat ground, warm weather). Three listings couldn’t be audited at all — and the reasons why are instructive.
This is not a lab test and not a survey. It is applied physics with stated assumptions — which is exactly what makes it honest. If you disagree with a row, the methodology section shows every number that produced it, so you can check the math yourself.
How to read this table
- Battery (Wh): watt-hours, computed as volts × amp-hours from the listing’s own spec sheet. This is the fuel tank.
- Claimed range: the headline number from the listing or manufacturer page, captured 2026-10-04. Where a listing gives a range (“35–60 mi”), we audit the headline (the larger number) — that’s the figure doing the selling.
- Implied Wh/mi: battery Wh divided by claimed range. This is what the claim requires the bike to achieve — its miles-per-gallon equivalent.
- Physics-checked range: usable energy (headline Wh minus ~12.5% unusable reserve) divided by the typical consumption band for the bike’s category. This is what the same battery delivers for a real rider.
- Claim ÷ reality: headline claim divided by the midpoint of the physics-checked range. A 2.0× means the headline is double the physics estimate.
- Verdict: Implausible = the implied consumption is below what physics allows for real riding in that category. Optimistic = achievable only under the kindest test conditions. Plausible = inside the typical band (no listing in v1.0 earned this).

* Row 7 (E500): “E500” is a model name shared by multiple sellers whose spec sheets contradict each other — 48V 15Ah, 18Ah, and 20Ah versions are all listed under the same name, with claimed ranges from 35 to 60 miles. There is no single claim to audit, which is itself the finding. See our E500 disambiguation review for the full picture.
** Row 8 (CTVXXC): a 6000W dual-motor machine capable of 45 mph is not a bicycle-class e-bike — it’s an off-road e-moto, and standard e-bike consumption bands don’t apply. Checked against realistic e-moto consumption (50–80 Wh/mi at speed), the 70–100-mile headline implies roughly 19–31 miles of real use. Included as a category warning, not a like-for-like comparison.
What the index actually tells you
Finding 1: The headline is the fantasy; the physics is the budget
The median claim-to-reality ratio across auditable rows is roughly 2.6× — the typical headline promises more than two and a half times the physics-checked range. This isn’t a few bad actors; it’s the industry’s standard marketing grammar. The practical rule from our decision framework holds up against all 25 rows: expect 60–70% of the claimed range at best, and plan around the physics column, not the headline.
Finding 2: Five claims fail physics outright
The Vivi 26″ (row 18) is the clearest case: a 288 Wh battery claiming 50 miles implies 5.8 Wh/mi — below what’s physically plausible for a bicycle with a motor, a battery, and a human aboard. The Engwe EP-2 Pro’s “up to 80 miles” from 624 Wh (7.8 Wh/mi on fat tires) and the TotGuard’s “up to 60” from 374 Wh (6.2 Wh/mi) fail the same way. The XPlorer’s 60-mile headline (11.2 Wh/mi on fat tires) and the Aventon Soltera.2’s 46-mile claim (7.5 Wh/mi) sit just under their floors — borderline, but borderline on the wrong side.
To be fair to Aventon: it’s one of the few brands that publishes ranged, rider-weight-specific estimates (20 miles throttle to 46 miles pedal-assist for a 160-lb rider) rather than a single fantasy number. The methodology still flags the headline, but the brand’s underlying disclosure is better than most. Headlines are the problem; footnotes are often fine.
Finding 3: The honest listings cluster at ~2×
The best-behaved rows — Ride1Up Portola (1.8×), Velotric Discover 1 (1.9×), Lectric XP 4.0 (2.2×) — still overclaim by roughly double, but their implied consumption sits well clear of the implausibility floor. There’s a meaningful difference between “optimistic under ideal conditions” and “impossible under any conditions,” and the index exists to draw exactly that line.
Finding 4: Some listings can’t be audited — that’s data too
The isinwheel (row 3) publishes no range claim at all — arguably more honest than a fantasy number, and a reminder that “can’t audit what isn’t claimed” cuts both ways. The E500 (row 7) shows the white-label problem: when three sellers list three different batteries under one model name, the consumer can’t verify anything, which is a finding about the marketplace, not the bike.
Methodology v1.0 (so you can check our work)
Energy: Wh = volts × amp-hours, taken from the listing’s own spec sheet. Usable energy = 87.5% of headline Wh (the top and bottom of a lithium pack are held in reserve by the battery management system).
Consumption bands (typical real-world consumption for a ~170-lb rider at moderate assist on flat ground; floors are the physical plausibility limit for real riding):
- Commuter / city: typical 15–25 Wh/mi; implausible below 8 Wh/mi
- Folding: typical 15–28 Wh/mi; implausible below 7 Wh/mi
- Fat-tire: typical 25–40 Wh/mi; implausible below 12 Wh/mi
Physics-checked range = usable Wh ÷ typical band (high end of consumption → low end of range, and vice versa). Implied Wh/mi = headline Wh ÷ headline claim. Verdicts: implied below the floor → Implausible; implied between floor and typical-low → Optimistic; implied inside the typical band → Plausible.
What this method doesn’t do: it doesn’t account for rider weight, hills, cold weather, throttle-heavy riding (all of which reduce range further), or unusually efficient setups (which is why “Optimistic” means “possible under ideal conditions,” not “false”). It audits the headline claim, not the bike — a bike flagged here may still be a good purchase at the physics-checked range.

Listings change; claims get quietly edited. That’s why the index is versioned — see the changelog below.
Disagree with a row? Check it yourself
Every number in the table is reproducible in under a minute: take the listing’s volts × amp-hours, knock off ~12.5% for reserve, divide by the category band above. If your result differs from ours, the most likely explanations are (a) the listing’s specs changed since our capture date, or (b) we applied the wrong category band — both are correctable, and corrections are welcome. Run any single listing through our interactive spec-claim audit tool for the same math applied to a claim of your choice.
Changelog
