All this if taken literally and out of context can just be so much nonsense. Under repeatable test conditions, yes you can test for maximum output, lung capacity etc. works fine up to a point on the track - a little less so on the road for diverse reasons Now to the bike, Are you sure that scientific methods actually work that well to the point you are presenting, I'm not not sure. Racing standards are set by the benchmark already set. If that benchmark is raised a lot higher are you blaming the bike technology? If so you are on a losing streak. Track racing in GB has risen, no question about that but study the reasons. Amateurs are Pro's now - no work considerations. many older track riders would loved to not have that roofing job(s) to complete etc. (example) On the road, with these modern tech bikes - is the performance that much better ? I don't think so. Have you studied average speeds from the late 50's to now from anything from the 1960's Milk Race (Tour of Britain) to TDF / Giro / Paris Roubaix - other classics, I have and quite apart from discrepancies about exact length/ timing /weather/ wind etc - nothing that much has changed - check it out for yourselves. This is all an industry led argument.

I can break the hour record using an electric bike that looks like a vintage Raleigh.
With concealed battaries inside 531 tubes. -
After watching these documeteries I translated it to my mountain biking. My speed in general as well as downhill offroad is astonishing. I've got up to 55mph and 60mph a few times downhill. I've done 30mph on a fairly flat route. All down to changing my body position. Tracked with a GPS and the mapping is accurate.

Great video.
