I tracked down the at the time humorous piece in Cyclismag. It was from April 11, the day of Paris -Roubaix.

Rumor Cancellara

The secret of Fabian Cancellara? A dynamo hidden in his pedal, allowing it to move faster. The fantasy is all the funnier it became in an uproar within the platoon. A French rider has reported to http://www.cyclismag.com this "noise" surprising. Those who really believe the arguments brandished as many changes as Cycling Cancellara operates at full speed. It is already more original than a suspicion of doping!

Sorry, it's in their archive, and a link only goes to the current main page.

Lance did a bike change on the run up to Bonny Doon yesterday.

Strange, he did not have a flat.
Phil and Paul were puzzled.

Might need to add this to the Myth.
"It is not about the Bike"
Liar.

I think the rumor started with this statement and the press ran with it.

"Lance Armstrong is coming down this finishing straight like a Grand Prix motor car!"

If you allow electric rider aids like Di2 into the drive train, motors won't be far behind. Only mechanical, rider powered systems should be allowed, otherwise, go and watch F1 or MotoGP. How long till the GPS unit monitors the power meter, checks against its preset course profile and shift the gears automatically? Ban Di2 now.

I like the cut of your jib, whatever a jib is. I think a rule that only allows rider powered systems with the exception of simple cyclometer would be a good rule.

I want to get my hands on one of these hidden motor systems. It would be fun to dress like a total fred with jeans and a T-shirt, show up at a century, and put the hurt on people.

There's no way they could keep such a thing a secret. It would require a big team of highly skilled engineers to design and advanced manufacturing to make it small, light and quiet enough. Word would get out.

I knew it. I have had a sneaking suspicion that the pros have been concealing 50hp kinetic motors in the bottom bracket for years. Now, i know for sure why their is such a distance between their performance and mine. Damn cheats!

Such engineers and such secrecy exist. I did occasional product analysis for a venture capital firm and once saw a drill no larger than a fountain pen that drilled through 1" of hardened steel in seconds. My firm did not fund it, and I think the guy ended up with a military contract.

Interesting. The links I posted were from a year ago, so there's been time for improvements. And this was just the brand named in the article as an example - it said there are others. The limiting factor for this one would be that they need to limit the retail price so that the people it's marketed to can actually buy it. I imagine noise could be cleaned up with more expensive materials. If you could reshape the battery so it would fit in the bike, that could put everything out of sight.

Dear Diary, the story of the invisible scooter, which saves effort with a "pedal assistance," is holding bank Giro. There are developments: UCI, the world federation, announced spot checks are also used on bicycles here. . The suspicion that someone has quickly developed the mechanism by the Austrian "Gruber Assist" is so successful, that the highest international executives intend to move very firmly. . Already have alleged that some of the latest bikes classic Nordic Flanders and Roubaix in particular, were delivered to the technical committee for detailed controls. As the first touch of the Giro d'Italy.

"There's a lot of concern, we can not waste time 'talking is, engineer Mark Bognetti, Italian consultant of the' materials unit, a special group of boffins upholds the technological development of cycling, President Jean Wauthier. Always Bognetti "For the record, we are moving from the last Tour We found that this mechanism can save between 60 and 100 watts, which becomes a huge advantage in the finale of a long race. The checks are in progress, others are planned. Our engineers are still developing a special scanner that can detect the hidden motor inside the chassis. . It will soon be introduced and all the great bikes cycling will always be verified ....

The motor must be quiter than me puffing up the hills.
Then it will be a question of what packs up first the motor or the rider.
I got Pixies at the bottom of the garden behind the goosbery bush.
Just get the little people to pedal the bike.

Pat is from the land of Lepricorns they will beleive anything.

I think this also explains why some of the guys I ride with drop me at times. It's not because they're better than me, but they secretly have motorized bikes, which I can't be expected to keep up with. Now I can re-write history and declare myself the victor in all of our group rides.
 
Here's the response from my friend who is working on the next generation of engines, fuel cells etc. A very smart guy.

The only way you could do this would be to store energy in a tiny flywheel in the hub, if it was made of a dense enough material it might help. No idea how you would control it so that you could engage the energy when needed in a way that it would be undectetable. Putting in an actual motor would imply a battery which in principle could be stashed in the frame. The extra weight would not nessecarily be worth it as the power density would not be high enough to overcome the cost of the biker pedling it up the hills. So in conclusion you have to be kidding me...

Keeping the number of people involved down

Isn't the only person who is allowed to work on a certain triple grand tour winners bike his brother?

FWIW, I have two pedelec's (electric assisted bicycles) and they are completely silent (note, that is at 20mph).Being in a peleton is also rather noisy (woosh!!!).

I'm not convinced sound is a dealbreaker. I just think chances of detection and resulting ridicule are a show stopper.

Still think this is not true *cue Benny Hill*

His brother is his manager. His mechanic is a gentleman named Faustino Munoz. You can see him in action here.

I thought I'd bump this one, because the story is gaining ground. The Giro announcers for RAI Sports got their hands on one from a bike builder who wanted to stay anonymous. Cassani rode it and said he got up to 50 kilometers an hour with no difficulty. They showed how it works during their Giro post-stage show. There was a story about it in L'Equipe.

http://www.raisport.rai.it/dl/RaiTV...284-4871-4039-9ce8-2133a47be7ea-raisport.html

...has made a bike built by a builder who insisted on anonymity and declined to be frame.
"This bicycle - Cassani said presenting - in existence since 2004, weighing 9 pounds and weighs 50 grams and its manufacturer swears that some professionals have used it. The battery is positioned in the seat tube near the pedals, while the small button to activate the mechanism is hidden under the brake lever. I tried it a few days ago, I was completely surprised them: with a bike as I cycled to 50 hour without problems, without fatigue. In plain helps the motor, if it helps altroché ...»
