How We Rate
How we rate
Every rating on Gear Matrix is published alongside the information it is based on, so you can judge the score for yourself rather than take it on trust.
Gear Matrix ratings are editorial assessments built from published manufacturer specifications and comparative specification data. They are not presented as the result of physical product testing. Where an article is based on a first look, a launch announcement or a press release, the article says so.
Weight-to-power on e-MTBs
Where a weight-to-power ratio is shown it is calculated from two manufacturer-declared figures: the bike’s weight in kilograms and the motor’s declared output. Both inputs are required before any ratio is displayed. We never estimate a missing value, and we never infer a figure from a different model in the range.
The full breakdown of rating criteria is being prepared and will be published on this page.
