Mechanized doping

Yes, you saw correctly.  Not only do we have Floyd saying that he has doped his entire career, and willing to come forward with the means he, and - according to him - several others have evaded doping controls. We now have people saying that some riders are motorizing their bikes to get an unfair advantage.  Most of the stories I have heard are the riders will use the bikes in the first part of the race, to save their legs, and then switch out the "assisted" bike claiming a mechanical problem for a traditional bike just in case the bike is scrutinized at the finish. 

The mechanisim in the video appears to be a Gruber Assist.  The video also seems to be pointing a rather accusing finger at Cancellara - even thouth they say that they aren't accusing anyone of using mechanical assistance.  Until they come up with concrete evidence that he has been riding what amounts to a motorbike in the peleton, I'm going to believe that he is innocent.

at 1800£ ($2600) it is a much cheaper means to cheat, especially considering Floyd has said that he spent about $90,000 a year doping.
