I'm not sure about the whole motor thing, but I could see it being true and Floyd not having first hand knowledge. Hamilton talks a lot in his book about there being an additional circle with Lance, Johan, and Ferarri that no one else was a part of. Basically Tyler was insinuating that Lance had a secrete weapon aside from the things everyone else did (test, epo, and BBs). Who knows what this weapon was. Maybe it was an additional BB. Maybe it was synthetic hemoglobin. Maybe it was a motor. Lance himself would say that he was doing exactly what the other guys were doing and he was just better. Point is, I can see motors (if they exist) being another level of secrecy. Floyd spilled the beans on what he knew, but I think its possible he wouldn't have known. However, to your point, Floyd did win the tour in 2006 and if motors were widespread one would imagine that Floyd would have needed to use one. And I don't think Floyd was holding back info when he finally confessed.
yep
