PowerInsight’s six-part ride report

Editorial interest 77/100 Selection signal · not a rating of the site

PowerInsight turns .FIT or .TCX cycling files into a plain-language power analysis, computed in the browser.

Landing page captured for the 2026-09-24 issue.

For: Cyclists analyzing power-meter ride files
Worth noticing: It declines to rank riders because its reference tables are not solid enough, and says single-sided meters cannot answer left/right questions.

Field notes

The described workflow accepts .FIT or .TCX exports, with weight, FTP, and other profile details optional. The site says missing inputs are called out instead of estimated around, and a critical-power fit appears only when the ride contains sufficiently long and hard efforts. Multiple files lead to a longitudinal report; saved rides build a history, with trends described as available after five rides.
