The amount of energy in a battery pack the size shown in the video
would be roughly equal to 1 or 1 1/2 of Fabian's pedal strokes, not
even remotely work hauling the extra weight around. That's taking into
consideration UCI weight limits.
Looks like to me the amount of No Load spinning in the Video would be
about all you could get with out adding 40lb of battery.

Nice link. The guy obviously did some work and to a first
approximation the numbers look believable.
The odd thing is: if you were going to pick an attack which
demonstrated something fishy, that wouldn't be it.
You know, his bridge up to the leaders at Beijing was more physically
impressive.
The attack in the gutter at Paris-Roubaix was well-timed, but nothing
that hasn't been seen before in that race, at around that time in
proceedings. If that's the only indicator, it isn't convincing. So
somebody doesn't necessarily know something, but they think they
might. A tip-off, rather than a smoking gun.
Boardman's "1kW from an AAA" is nonsensical. A power recovery system
that got back more than a small fraction of power input would be of
interest - but the power still has to come from somewhere.
Let's say the rider sits in the bunch for 5 hours - we know from
previous analysis that he can cruise and expend 100-150W. Let's say
he puts in 200W for 5 hours instead of 150, so there's 0.25kWh to play
with.
He needs 1500W for 10 seconds, that's only 0.004kWh. So the system
doesn't even have to be that efficient. If it exists, he can spin it
up for only 15 minutes at 50W excess input power at 33% efficiency.
The only real clue we have at the moment is Phil Liggett's potentially
Freudian "He's a machine" line
Anton Berlin
The author is biased. He has a obvious man crush on FC. ( looks like
it's been going on a year + now )

If I was Fabian I'd get an ex parte before this stocker does something
creepier than advertising his love in a blog.
