Is a new thread is in order? This one was originally about whether something was fishy regarding Ryders bike, based on a video.... I think that the majority of clinicians agree that at best (or worst?), the video evidence is non-conclusive, and not significant evidence of a motor. You all know my position on it.... I think this conversation is over and will not be contributing further to this unless a decent argument comes out in favor of the motor theory.
However, I think the conversation regarding motorized bicycles in the pro-peloton has far from run its course. In particular, I find the warnings from ex pros, such as Boardman to be interesting. I also am interested in a discussion about the current extent of bike inspections vs the extent warranted (given the state of technology today). It's not clear to me what the standard procedure for a UCI bike inspection is, what sort of motor it would uncover, and what sort would *likely* go undetected.
Another interesting topic: A lot of posts in this thread allege that a hub-motor would be the best way to cheat. A lot of other posts allege that a hub-motor would be too small to be practical. Does anybody have any evidence, one way or the other? I've done a bit of googling around to look at various hobby motors, and the like. Intuitively, I am inclined to think that a hub motor could be built without *too* much difficulty that is able to provide ~20W power. IE, a useful amount, but not a MAJOR difference maker, once you account for the extra weight of all the equipment. However, this is really just speculation on my part. One big obstacle to a hub motor is power supply, as I cannot think of a reliable way to provide power to a racing style road bike hub that would not be immediately obvious. Electrical Contacts embedded right into the dropouts? Maybe. In any case, the sophistication and customization would require input from a team of technicians / mechanics / engineers that is serious about putting a motor into a performance bike hub. Starts to look like a much bigger conspiracy than just a racer and his personal mechanic.
I am very interested in the most recent allegation that Contador changed bikes after being warned that the stage winner's bike would be inspected. Is the winner's bike normally inspected? Can this be confirmed / proven by somebody? While not at all conclusive, this would be an interesting development. At the very least, it would *suggest* that contador's bike was not up to code. I know he has a history of switching bikes though for a favorable gear ratio, so that's really all we can say.
