The latest accusations emerged Sunday on Stade 2, a sports program on the French television network that is also the host broadcaster of the Tour de France. The report suggested that motor doping is also at the highest levels of the sport. Suggestions that top riders are rigging their bikes have escalated in the past several years. As was the case in the early 1990s with more conventional doping, riders who are the targets of such accusations have dismissed them." Sort of old news, but it looks like the main stream have picked up on it now. There have been rumors for a while now of people using motors (see examples below), most notably Fabian Cancellera performing super-human feats with seemingly no effort. See odd hand motion at 2:32 followed by putting 300+ yards on arguably the other great cyclist of the event in only a few seconds. He has done this several times in other races which led to suspicions. Bike wheel has a life of its own. It seems that no matter what, cycling will never be clean.
