It must be quite hard to properly test bikes though. Given most of a bike can be tweaked by just a few simple things (seat, tyres, bar, stem etc) and those tweaks will make it feel quite different.
Also, I bet most tests are not scientific – you and your journo mates get to ride some demo bikes for a bit and then your fed beer and grub while listening to the marketing powerpoint.
Then you have a deadline to file a readable report with pictures.
Its most likely to be made up.
Whereas if id test them id do timed laps of a trail, in set conditions and have to spend a few days testing, checking and calibrating and fiddling – all for the conclusion that most bikes are fun to ride.
