The doped bike exists (video of pro version)!

[Nearly]

Breaking news: AFLD busts Spartacus! Tests positive for Ducatti DNA. Suspicion raised initially by enemacam revelation on Your Tubes. Specialized Shivs banned for driving unregistered motorised vehicle - sold by Riis on eBay to finance Fab's fuel needs.

 

[DAOTEC]

Mr. 60+ teams up with Mr. 50+

So Contador can give it a try with Riis in the next Tour de France if he gets in trouble to win it

 

[nia O'Malley]

Gee, if everyone's a suspect. ..... what would be said of Eddy Merckx in today's climate of suspicion?

Would he be doped both physically and mechanically?

What a sad joke this sport has become.

It's just back to basics, is all

The winner of the 2nd Tdf in 1904 was disqualified for using a train on a night stage after all.

x ray of the bike behind podium for first finishers. I hope the uci know what they are looling for, it can be tiny.

Found the thead so put this in here.

Why is Frankie Andreu pointing this out if it isnt a possibility its being used ?

UCI check 36 Milan-San Remo bikes for motors

where are all those posters who were laughing at this possibility ??

I agree. I still say Cancellara doped ... I just don't see anything except an engine being used.
Its just to easy

UCI really committed to catching teams cheating...

Teams were notified 20kms from the finish that there would be bike checks.

And people think Cookson is anti doping. HAHAHA!!!!

Here's a selection of reactions to the epic "Ryder Crash - Motor?" thread.
Would be good to hear back from the same posters, also in light of the CIRC report where motorized bikes are mentioned.

Not so convinced about Ryder. Cancellara was the controversy that made the UCI start checking bikes. With good reason I think.

by the way, haven't seen Granville57 for a while now. Is he still around?
He was on a roll in that thread.

 

[Catwhoorg]

His profile shows him as banned if you click on it. Not sure if that's a time based ban or permanent.

CIRC report has revitalized suspicions.
Not so convinced about Ryder either, but point is the speculation was fully justified.

You didn't quote me, but my opinion remains unchanged.

And, sorry to cite your post here as we already have a healthy debate ongoing over another subject.

Engineering, configuring, sourcing the requisite parts, manufacturing and actually hiding a motor in a bicycle is one thing. The physical equipment is the first challenge, the control software and the operating design (single cadence, cadence range, on/off, etc.) to support the requisite 'duty cycle' in a TdF stage or a TT another.

Integrating an appropriate storage capacity remains, in my opinion, the most problematic of all. How would you power the kWh required for meaningful boost? Supercapacitors, Li-ion, Lead-acid, NiCd, NiMh, all would probably support minutes at best with any meaningful power outupt. That moves you to consider NaS batteries and flow batteries. Not likely.

In terms of checking the frames, they don't need to look down the tubes. Just put your hand on the frame and check to see if it is really, really hot.

Notably, there are lots of start-ups and others trying very hard, with lots and lots of other people's money, to make e-bikes. They are all at least a few light years away from anything like this or anything that could broadly be described as 'seamless integration'.

Even though the initial concern regarding Spartacus and Ryder was raised from outside the UCI, the picture of the officials looking down the seat tube deserves a caption along the lines of 'looking for dope in all the wrong places'.

Notwithstanding what CIRC had to say (they are obviously not engineers), it would be more believable if this were some sort of conspiracy to pretend that people were looking for rule infringement while letting cyclists cheat by doping like crazy.

Dave.

Let's do a few quick back of a beer mat calculations here.

Top end mobile phone battery is 10Wh (Watt-hours). Say you could squeeze 10 in a frame somewhere, that is 100Wh (6000Wmins). Assume no recharging and a perfect motor, max rider wattage sustained = 6W/kg, average weight 60kg = 360W. So using all the energy in the batteries would allow freewheeling uphill for 6000/360 = ~17 minutes. Worth it for the last climb at MSR for instance? Would allow the sprinters to hold on ready for the sprint. You could recover energy like a Prius too downhill. Marginal gain. You could hide the batteries in the on bars soap dispenser.

matti breschel was riding out of his aaaarrrrssee on CSC-tiscali or CSC-Saxo that year. he has never touched that form since. He was riding like Greg Van Avaermart has been. But Breschel is about Daryl Impey level, damn solid, but not a champion. Van Avaermart or however you spell it, is better, but he is not Philippe Gilbert. even tho Gilbert was still doping like the rest of them.

 

[blackcat]

hypothetically, if a powerful team like USPS in 2002, or Sky in 2014, is using a motor -this is a hypothetical remember, if a power team, if a power team is winning the Tour going into the final stage, when it is uncovered, is it not covered up?


I wanna know Race Radio's opinion. I heard from RR and Betsy they were getting the knives out for Rass before the Tour, and they were ready to swoop during the tour, not because he got in yellow, but the info from the MTB'er about the artificial hemoglobin in the northwave or sidi or Time shoebox, could not be suppressed any longer, and Rass had to pay. It was just a coincidence he had won the Tour when they pulled him.

my caveat, well, there is the devils advocate. Rabo were one of the few strongest teams, Verbruggen is Dutch too (or is he Belge?), so, Rabo did have the deck stacked in their favour, but they were still f'ed over.

is not a tell, the fact that no-one has sought to capitalize on any advances and commercialise this. even if it is only 50 watts for 5 minutes.

if you use PEDs filtering onto the blackmarket after Armstrong/Froome/Wiggins get their hand on them, a rough rule of thumb ~5 years, then we should start to see product available thru other channels. Certainly the norcal and socal midlifecrisis dopers doing tris and fondos, would look at this, and it would build to be more than whisper.

the counter-factual, is the meta answer.

 

[Chipist]

Maybe this is why Sagan keeps pulling wheelies, it is the motor at max watts! Also a clue, must be driving the back wheels and not the front. How long before we see spoilers on bikes?

but Sagan has always been the phenom, starting at Tour Down Under he did well as the 19yo showing up all the pros. I cant even remember the team he rode for, Liqui Cdale i assume, it was italian, dont think lampre

It's very simple, really. The "usual handful of people" were totally being "conspiracy theorists". I stand by what I said, as I would even if it was proven that Hesjedal or anyone else used a motor, because what you guys were posting in that thread wasn't motivated by the evidence at all. It wasn't rational. If it turns out Hesjedal was somehow using a motor, then you'd be right, but for all the wrong reasons, so it'd be more of a fluke than a win or a vindication.

That said, what does this prove? They were already looking for motors after the Cancellara thing. Nothing has changed.

did not buy the hesjedal occurrence. but, i was suspicious of Cancellara, more so on the flat, but i was never high level, when he went away in Flanders on the flat from the front group, they let him go yes, but they would have been spinning at 40kmph, now, when this 15 man groupd are just rolling thru, it looked like Cancellara just went away putting out 500watts, but not exerting this force. Well, if anyone could look effortless, and put out 500, only two could do it, and not sure Boonen was in the group or in form this year. He seemed to put out significant power, but it looked effortless. And I am not confident in my appraisal, because I am not a racer.

 

[Archibald]

considering that the following year, Boonen rode away and solo'd from an even greater distance... and 3 Sky riders couldn't gain ground on him... yet no one's saying his bike had a motor.

currently we're at the entire peloton being "never tested positive" for these mystery motors, when you'd think that they'd be much easier to find without the aid of microscopes or lab equipment and medico's...

Ha ha.

Here we go again.

Let's assume a perfect motor?

Ok, let's assume there is no gravity, and that the cyclist rides in a complete vacuum while somehow managing to still breath.

Dave.

P.S.

Ok, I will offer a tiny bit of education here, though I imagine that it will be completely overlooked as even more crazy estimations continue.

Motor efficiency (e.g. brushless DC) is high at low power output, and tails off (to zero actually) at maximum current draw. At maximum power, efficiency is perhaps 50% of its peak.

And that is just one minor engineering issue to grapple with.
