The honest core of this site

How we rate helmets

Every claim we make about a helmet rests on this page. In a safety-critical category, if we get this wrong, nothing else we publish is worth reading.

We do not run a crash lab. We don't have one, and we're not going to pretend we do. When a safety number in one of our reviews came from someone else's lab — SHARP, a standards body, a manufacturer's homologation — we say whose it is and we link to it. When we couldn't verify something, we say that too, in those words, on the page.

What we actually do

We research. Specifically, we work from:

  • Published manufacturer specifications — treated as claims, not facts. We write "Klim rates it at 1,450 g", not "it weighs 1,450 g".
  • Certification and the standards bodies. We read the homologation on each model (DOT FMVSS 218, UN ECE 22.06, Snell M2025, SHARP) and cross-check it against what each standard actually tests. Every certification claim on the site links to its source.
  • Independent third-party testing— above all SHARP, the UK government's program that buys helmets off the shelf and impact-tests them. We cite it by name and link it. Borrowing someone's credibility with attribution is honest; implying their measurements are ours is not.
  • Aggregated owner reports — treated as evidence, but weak evidence. A recurring complaint across thousands of riders is a real signal about comfort, noise or reliability. It is not a substitute for a specification.

The US-versus-Europe rule

This is the discipline that defines the site. Many flagship helmets sold in the US are a different homologation than their European namesake — often DOT or DOT + Snell rather than ECE 22.06, and sometimes a different model name. We always give the US-market certification first, because this is a US site and Amazon.com sells you the US build. Where the European version differs, we note it and cite it — never misattributing a European SHARP star to a differently-homologated US unit.

What our scores are, and what they are not

Every helmet carries five metric scores out of 10, and an overall score that is simply their mean. These are judgments from documented research.They are not lab measurements, and we will never present them as such. We publish the rubric because nobody else in this category does — if you can't see what a number is made of, the number is decoration.

The five metrics

Certification
The strength of the marks on the US-market shell — DOT (floor), ECE 22.06 (rotational-test gold standard), Snell M2025, and SHARP stars where independently tested. This leads every score because it's the only objective pre-crash safety data.
Weight
From the manufacturer's published grams. Lighter means less neck load in a crash and less fatigue on a long ride — a real factor, judged against the category.
Quiet / refinement
Wind noise, seal quality and finish, from aggregated owner reports and our reading of the design. What you live with every ride.
Fit & versatility
Head-shape suitability, field of view, and configuration options (peak, sun visor, comms readiness) — weighted by whether you'd actually use them.
Value
Performance and certification per dollar at the LIVE price — so this metric, and the overall score, move when the price does.

Why our scores can change without the helmet changing

The Value metric is computed against the helmet's liveprice. So when a helmet drops in a sale, its Value score rises and its overall score moves with it — even though the helmet is identical. That's deliberate and honest: "is this worth the money?" is a question about the money, and the money changes weekly.

How the prices work

  • Prices come from the Amazon Product Advertising API, refreshed daily.
  • Every price is stamped with the date we fetched it. The most recent refresh was Jul 21, 2026.
  • If our price data is more than 48 hours old, the number disappearsand the button falls back to "Check price on Amazon". We would rather show you nothing than a figure that has rotted.

What we will never do

  • Write "we tested", "hands-on" or "we measured" — because we didn't.
  • Invent a price, a certification, a weight, or a SHARP rating.
  • Publish a customer testimonial. We have no customers; we sell nothing.
  • Let a commission rate change a ranking.
