Indoor Trainers · Power Meters · The Pain Cave
Smart trainers and power meters, compared on the specs
Trusted, spec-first picks for the rider who's upgrading, not starting over. We compile every published spec and accuracy figure and do the watt math. Units we claim to have bench-tested: 0 — and we say so.
What we did instead: read the manuals, compiled every published spec and accuracy figure, and did the watt math you can check. See our method.

Why trust us
The site that admits what it didn't test
Live, dated prices
Every price pulls from Amazon and is stamped with the day we checked it. No live number, no number — we show 'Check price', never a stale one.
A published rubric
We score accuracy, road feel, value and noise on a consistent scale you can see, using manufacturer specs and manuals — not a black box.
No fake test lab
We don't claim to have bench-tested twenty trainers. We compiled every published spec and did the math you can check yourself.
Buyer-first picks
When Amazon is the cheaper option, it's the pick — even when another link would pay us more. Commissions never move a ranking.
