Values come from the MERACH S29 Amazon US listing (checked November 2026), completed from the maker’s page for the same model only where the listing is silent. Neither states the labor warranty, user height / inseam range or the heart rate, so they score zero in FitScore and are marked “Not stated” where shown.
