Not to add any fuel to the fire, but after about 10 seconds on google I found this:
http://www.reefbikes.com.au/invisitron-r1-electric-bike-carbon-road-racing/
This may have been presented before, but it at least adds some credibility to the fact that it's possible.
That's not to say that I think this is what has happened in this case, or that I think that the pro peloton are using bike doping, but the fact that this is now commercially and readily available leads me to conclude that with the budgets of pro teams, that a beefed up version of this would be very easily possible. Once again, not saying that I think this is what is happening, just that it definitely shouldn't be mocked as much as it is.

Ryder is all over the place trying to gather his bike. Walks to the right, only to find out his bike is about to spin all the way to the left.Archibald said:

We sceptics aknowledge we don't have the training or the education to be suspicious every time something weird happens, because freak occurrences are a fact of life and have a perfectly normal, scientific explanation. I see Hesjedal's bike doing a funny thing, but I don't see any reason to believe it's due to a motor.sniper said:
I just experimented with my bike in a similar position on the road to Hesjedal's and i simply cannot believe it could possibly have moved like that due to a spinning rear wheel (i also dont think it would have still been spinning due to the contact with the ground for what looks like a good second or so). Like i said before, it looks like the sort of motion you'd maybe see under gravity on a steeply banked velodrome but very hard to see how it would happen on this fairly flat road...

from the link posted earlier....one of the videos is interesting
THE REAR WHEEL - High Torque Performance - thats the speed which Ryders wheel was spinning and recoiling.

And they xray downtubes, not rear wheel hubs.
And there's enough pawls and metal bits in a rear hub that you'd not necessarily see it, even if you could reliably xray it.
Does this explain Froome's seated accelerations? And his belief that his victory will stand the test of time coz the doping was mechanical?

Woah. Didn't make it to the video section, but THAT is interesting...
Still not leaning one way or the other, but those dismissing this as easily as they are would be well served having a watch of that YouTube link.
One thing I'm certain of in cycling is that if someone thinks they can get away with something, they'll give it a go...

Energy density of the power source is the biggest issue.
A good number for estimating that is about 300 Wh/Kg. (with some leeway) There are some higher numbers available, but not likely to be used in this sort of application
A brushless DC motor may hit 90% efficiency, but mid-high 80's is more likely. They can be pretty compact.
I don't think it was happening with Ryder, it looked to me like gravity was the key.
Mechanical doping is a huge risk for a team, as it would have to be done with the teams knowledge and consent. If found out they could easily lose their license.

I agree. Trememdously risky for a team and it would not be so simple as to point the finger at an individual (and then fire them from the team) since they share equipment and a lot of support people would have to be involved.
That YouTube clip of the hub is interesting. A motor like that would provide plenty of energy savings over a 200+km course. I'm sure we'll be seeing them at Gran Fondos and the Master's racing scene soon, if they aren't there already!

What noise? You can't be serious? The first video sounds no different to cranking up the speed - and that's in a studio. Add wind noise of 30-90km/hr and you'll hear nothing.

You'll definitely hear that when riding next to someone.

The clinic is in full *** mode...which isn't anything out of the usual I know.
But, the rear wheel was spinning, causing a gyroscopic effect, as well as it being a steep downhill, and the bike was partially balanced on the pedal, making it easy for the bike to rotate...

Granville57 said:Not sure how you're arriving at that conclusion.
I would agree with that. I'm just confused as to why Freddy feels that the moto driver and Hesjedal "don't see that bike turning on its own."Archibald said:
As in "they didn't anticipate it"? (which I would agree with)
Or "they didn't witness it." The implication being (I thought) that had the moto driver witnessed it (or at least noticed what was happening), he may have made a statement afterwards or some such thing (even though in real time, this whole thing would've transpired rather quickly).
Maybe Freddythefrog could clarify exactly what he meant. I think there's just a simple misunderstanding of each other going on here.

I've said this before, but I feel very strongly that if anyone were ever found to be mechanically doping their bike in the pro peloton, there would have to be lifetime bans for rider, mechanic and DS. No way such a thing could take place without the knowledge of at least those three people. No way.
It would be such an egregious distortion of the sport, so thoroughly premeditated and with such a high degree of complicity among such a trio (if not more people), that it would have to result in lifetime bans.
Otherwise, what would be the point of any rules whatsoever?
Bike doping = the worst of the cheating offenses.

My sentiments exactly. Well, I guess some people find their April Fool fun any time of year they can manage to find it. 'Cause one thing for sure - it's either a fool's errand, or humor. I won't make any bets either way, although I do see some posts I could make a solid wager on the humor side.
My vote in the poll went for "Aliens abducted Ryder's bike and replaced it with a duplicate".
Because there wasn't a Vino option.

It really is that simple. It's an odd occurrence, even to the more level-headed folks like Cosmo and hrotha. It's worth discussing. Simple.
