The doped bike exists (video of pro version)!

Easy...

I don't even know if it needs a switch. Just set it to run at fractional power starting, oh, 45 minutes in and disengage when dead. They guy gets maybe a 1kj work reduction during a boring part of the race, or makes a break he wouldn't otherwise.

It's wrong, of course, and requiring inspection with clear channel down the seat tube, and an inspection hole in the downtube seems like it would suffice to avoid x-ray machines.

another example

another real implementation of similar tech:

Dump the seat bag and put the battery cells in the frame.It's a little noisy, but i'm sure that could be improved, and for pro use, you aren't going to hear it over the noise of crowds, motorbikes, etc... like when climbing the Muur in Flanders?

It's not a hoax. It was part of the official Giro d'Italia post stage show here.
http://www.raisport.rai.it/dl/RaiTV...284-4871-4039-9ce8-2133a47be7ea-raisport.html

If you read the Tuttobiciweb article I posted at the real, non-Clinic thread, you'll see that the bike was given to them by a bike builder who wanted to remain anonymous. If a custom frame builder can set this up, what could, say. Trek, with their "Formula 1" team devoted to helping Amrstrong win Tours do? He has his frames delivered by the Trek liaison in person - no giving them to UPS or FedEx. Then Lance flies them to races in his private jet, where the same guy from Trek puts then together. Just planting the seed, but if anyone in the peloton knew about ways too gain advantage, it would be him and Bruyneel.

Trek said:
Ok, I am not a Pharmstrong supporter at all, but why all these PED's and retirement if he could have continued to win with zero positive test risk with this silent bike motor? He would have beaten AC Dopador last year. No way Pharmstrong has used this. As the bike was supplied to Cassani by an italian source, it is highly likely that it was used by some italian riders, not? But who knows, one shouldn't accuse anyobdy without any substantial evidence. So most probably we will never know.

I actually now watched that part of Flanders shown on that video when I recorded it on TV (higher resolution), Cancellara does indeed fiddle around with his fingers but he doesn't change gears, no way. So what was that all about :confused:

could it possibly be he was slackening off the brakes that were rubbing after all the cobbles? i know on campag there's a button on the break lever that loosens the cable to the brakes. not sure about sram/shimano though.

amazing how cancellara rode so quickly away on the climb while sitting in the saddle dropping boonen who was out of the saddle.......if caught specialized might aswell give up bike racing and go into motogp....

I had to register for this one

OK his accelerations definitely look a bit weird. I don't know what to make of it but most of us mortals when we accelerate hard on a hill there is some body language that suggest effort. Look at Boonen trying to stay with him. FC almost looks like he takes a breather and just goes.

Whole thing reminds me of this.

one of the most impressive performances I have ever seen on a bike, is Cancellara in 2008 Tour de Suisse, stage 9 where he was off the front in about the last 7kms.

http://www.youtube.com/watch?v=iWljwietzYo

compare the upper body and technique.

I know the reference, is au bloc, over the last 7 or so km, versus the last 50km in Roubaix or last 30km in Flanders.

So, I acknowledge, he might be putting out, 550 watts in Suisse, versus 500 watts in the monuments. But one was riding away from classics riders, one was riding away from a Protour peloton on a flattish stage (which ofcourse, requires a massive effort, but not in the mode of the monuments)

opinions?

An Italian guy proved that Cancellara's bike at Flandres and Roubaix had an engine! Look at this video http://www.youtube.com/watch?v=8Nd13ARuvVE

All that proves is that there are a lot of guillible people.

Anyone with any clue about engineering or TV could tell that the Italian report was a hoax. A glimpse of the battery packs (disguised as bidons), visible wiring, barely suppressed smirks. A few other things too. No shame in missing this stuff - it's not your field.

Seriously. There is no electric (or otherwise) powered bike that exists that could be passed off as a regular bike. If you think there is then show me the patents for it.

Don't agree. Any one who takes a brief five-minute look at the remote-controlled hobby aircraft section of their local bookstore will think this could be a credible problem.

Miniaturized batteries have revolutionized the hobby in the last few years. Electric battery power aircraft have now supplanted gas-powered ones, largely because of lithium polymer battery packs.

Just take a look at the power/watts stats of these electric motors when they profile these planes and you'll be amazed. I can't remember precisely, other than that they put up many hundreds of watts, and can easily be way above 500 watts. These planes have huge power/weight ratios, largely from the revolution in battery power (miniaturized, light weight, with huge outputs and endurance that can now rival gas-powered planes). The profiles of individual planes give all the stats, including power/weight ratios, LOL. :D

I remember when looking at these articles thinking: "These things are putting out a hell of lot more power than Armstrong's fearsome legs".

The batteries are miniaturized. Can very easily fit in a seat tube. And seat tubes are long. There's lots of room.

These things would have no problem putting out more than enough power to push a cyclist, and if they modulate it for JUST :rolleyes: an extra 50-100 watts, the endurance/length of the boost would be impressive (far in excess, a huge multiple, of the extra weight).

LOL, I remember Devolder's comment before Flanders that if Cancellara is TT'ing at 60km/hr, he and Tom would be chasing at 50km/hr. These guys don't believe Cancellera, and this, from guys who are unlikely to be clean. Doesn't look like Armstrong/Michael Rogers believe him either, given their quips on Twitter vis a motorized Cancellara. They don't believe him.

Also: see these odd PRE-PLANNED bike changes like a F1 pit stop. Why?

http://www.youtube.com/watch?v=T25fqnRb-mU

I remember the rumour once about Heras' bike change at the top of mountain in the Vuelta, and some of his Liberty Seguros colleagues as well, and descending like rocks then, with Dennis Menchov not knowing what hit him. The rumour was they'd switched to bikes with heavy wheels. Ha, ha, ha.

The bike in the Rai report has a huge circular BB area to house the motor. Looks like a totally different system to the Gruber one. And that would be pretty noticeable to anyone who looks at the BB

In the video that supposedly proves it by showing him changing gear, when he is meant to pressing the on button. You can clearly see the Doubletap lever moving. Another thing it claims the motor moves at a cadence between 30-90rpm. Another moment where they claim he is using it his cadence appears to be about 105

It proves there are scary explainers out there. The video was part of the RAI Sports Giro coverage. The guy in the video, Davide Cassini was a former pro. He got a call telling him that the bikes exist, and told him where he could get one. His story is in L'Equipe, and knowledgeable people in cycling around the world are discussing it right now. A couple of weeks ago Cycling News already had a response from McQuaid, and the UCI is working on a way to test the bikes. This is real world, the story will be everywhere, and people who deny the existence of something like this are usually hiding something. Troll away.

No I agree the Gruber assist in combination with LiPo batteries could be used. The system highlighted by Rai looks like it needs a custom frame with a large circular BB with the motor also visible so their claims are the ones I'm questioning.

That video above then goes on to show the Gruber assist as if it was the same system. Anyway lets have all the riders with SRMs and HR monitors and submit their SRM files after every race, and while we are doing that use that as part of the Biological Passport ;)

(and I'm not trolling. I'm offering my observations, if you want to counter any of them go ahead.)
 
I cannot possibly be the only one thinking the following (and a comment or two from some of the real-life riders on here would be great)...

In my mind there would be a huge difference from a riders perspective to using PEDs and to using a motorised bike. Using PEDs, although wrong and all that, is improving YOU and it's still YOU beating all the others. With a motorised bike you're actually accepting that you can't beat the others with your own body alone.

So even if this machine exist (the RAI clip is not from April 1st, is it?) I think it would still be far-fetched to assume it's in use in the peloton.
