To my eyes, that bike obviously has a battery in the downtube. But I'm not the average person where bikes are concerned so perhaps I should have said, "a bike that would fool other bicyclists."
Assuming the pros are cheating, the professional assistance is unlikely to be of use to a regular human. At the professional level, a 1% gain could be huge, whereas a normal rider could gain far more than that by better techniques/breathing/equipment/whatever.
Give me a bike that looks like a normal bike and gives mere mortals like me an extra 5 mph (power law makes that a lot worse for pros).
