The balanced answer: 26.8 measured miles, 23.6 mph and dual disc brakes at a weight you can still fold into a trunk.

Claimed vs measured · every figure sourced
Manufacturers rate range with a light rider on flat ground in eco mode. Across twelve scooters ridden until they shut down, the average delivered 71% of its claim. We put the claim and the measurement side by side, name the source, and date it.
Top picks
The number-one pick from each of our main comparisons. Every one is ranked on a figure a named third party measured — never on the number printed on the box.

The balanced answer: 26.8 measured miles, 23.6 mph and dual disc brakes at a weight you can still fold into a trunk.

The lightest genuinely usable commuter we found data for — 26.4 lb, and it still measured 24.2 miles.

Rider Guide's best-under-$500 pick: 20 mph, 14.6 miles and 37.4 lb at a listed $439.

59.8 measured miles and 61.2 mph from a 3000 W street hyperscooter — extraordinary numbers, extraordinary caveats.

Start here
Most people arrive with one binding constraint — a hill, a flight of stairs, a body weight the category ignores, or a commute that is longer than the numbers support. Start with yours.

Range you can plan a commute around, weight you can actually lift, and brakes that work in the rain.

Ranked on the range somebody measured, not the range printed on the box. The gap averages 29%.

The least independently tested corner of the market, which makes the claims matter more and deserve more skepticism.

A payload rating alone tells you almost nothing. These have the range, brakes and frame to match the number.

Watts against your body weight, and an honest note on the suspension specs nobody publishes.

The reference section: real range, IP ratings, brakes, hills, legality, maintenance and safety.
Why this site is different
Every competitor in this category leads with a testing claim. We have no test program and will not invent one. What we have instead is something you can check in five seconds.
Each real-world number names the publication that measured it, links to it, and shows the date we read it.
Manufacturer figures carry a visible label. The distinction is generated from our source registry, so it cannot be dropped on one page.
Where no figure exists, the table says so. Brake type is missing for a third of models and IP rating for nearly half — that is worth knowing.
Scores are computed from specifications by formulas printed in full on our methodology page. You can check the arithmetic.
Read these first
If you read nothing else here, read these three. They are the reason the rest of the site is ordered the way it is.

The full claimed-versus-tested table. Average delivery 71%, best 90%, worst 53% — and not one scooter exceeded its claim.

Every number on the box, the conditions that produced it, and how far off reality it is likely to be.

It is a design limit, not a target. Hill climbing degrades first, then range, then braking — all well before you reach the number.
