Froome's Acceleration on the Bike ??

[Clausfarre]

I think it is a bit silly to discredit the idea by assuming it isn't possible. This isn't rocket science, it's small battery powered motor science.

But it may be silly because would they seriously do this - on a team level...? When it comes to cheating in sports I find that morals isn't really that big of an obstacle. Admittedly, I DO find this ridiculous...but I wouldn't ever claim that some riders or teams would never pursue this.

all of the systems about at the moment are noisy as they are geared, this was what was said about cancellara bike.to make these motors you need to use neodymium magnets these are very powerful and all you would need is a piece of steel to check for them it would stick to frame if a motor was in there. we are working on one that would fit in the bottom bracket the crank spindle will have a sleeve that fits over it and become the armature and use normal ferrite magnets that would be harder to find and noiseless and deliver 500w for 1 hour.

You are actively looking for a way to cheat?

Why? apart from the obvious financial gain i suppose.

Energy density of a typical Lithium battery is 1.8 MJ/Kg.

That's the equivalent of 280 watts for an hour.

To pull 500 W for an hour takes ~1.8 Kg of battery.

Given motor efficiencies, you are going to need 2-3 Kg of battery.


So yeah, this isn't going to be used for a whole climb. Its not the motor, its the energy storage thats the issue.

Some form of Nuclear power source seems to be involved then

All of this motorised bike stuff is utter, utter speculation. According to most Froome is already bang to rights as a chemical experiment, seems superfluous to add baseless innuendo of powered aid too. Silly season.

It perhaps warrants it's own thread, but not one directed solely at Froome IMO

some consider Froome's acceleration, in particular on Ventoux, as INSANE, ALIEN, NOT NORMAL

 

[JimmyFingers]

Wow, until you changed the font size and bolded it I never realised you felt that way.

It doesn't change the fact that no such motorised device has been found in a pro-rider's bike, there's little but hearsay that such devices even exist and are effective and nothing but an over-active imagination to link such activity to Froome. You even linked to a viral marketing video as 'proof'.

I mean if you're doping as heavily as you would have us believe Froome is, would you need motors?

 

[poupou]

That is an electric motor able to provide more than 200W

And there is battery prototypes with a much higher density than usual lithium.

you are on the right track with stepper motors sir
dyson of vacuum cleaner fame leads the way in small motor tech they have a big research centre in uk

no we are not looking at comp just saying it could be used in comp.
we are looking at it as a cycle aid has to be cheap and easy to install.

As I posted - I don't think motors are being used to cheat.

BUT... my job in the 80s - we could have done it then.
It is long from a technical issue these days to get big power short term needed to cheat. The issue is are they doing it (no IMO), not can they (yes).

The only real issue is long term power. I can't think of how to power it for a whole climb, or long TT, but for an attack, or sprint - it is not a difficult task.

Now that we Know with FACTS that such devices are being developed for awhile & with rumors being whispered about that equipment's usage in the peloton- I ask - what would be the penalty if someone is found using this kind of "doping"??? IMO this is even "WORSE" than medical doping, since is an advantage "beyond" the basic principles of cycling-and therefore should be punished with Lifetime ban without a doubt-that means the rider & the team.

The baseless innuendo has been about his doping.

Convinced he's doped to the gills? Well then, what is he taking? How is he passiing his drug tests?

I've yet to get a reply to this question. As for the motor, it's not a rumor. It's just something no one outside the small world of pro cycling knows about or has ever seen.

But it exists and it's been used by pro riders to win races.

Those that win the grand tours do so with a team, and lots of money.

So...how about there are no rules on this. Just have your bike weighed and if it is under 6.8Kg then you are fine - motor and all. It has been a long while since it has been just about the rider. I believe the motor would make about as much difference as the brand of bike that is ridden if everyone had them.

OR...its just like the doping stuff when anyone wins we spend a year questioning it.

Come to think of it, if they did this it might shut to forum down. Rather than talking about who has the better pharmacist it would be who has the better engineer. Shouldn't it really be that way anyway?

I did not know power supply was anywhere near that. That is huge.

Where can I buy that? I'm not a pro, just want to go on a local club ride and 200W might help me beat everyone. If they don't know I have it and I beat them is that immoral?

I have heard that Volvo did experiments for electric cars where the charge was stored in the carbon fibre of the structure.

 

[drawkrb]

with motors as in pic, you can hear the gears this is what they said about cancellaras bike it was making a funny noise that is where it all started.

Can anyone find the Cancellara thread discussing the motor ? and post it up please.

If anyone was to use one of these, better wait for a chaotic moment when one has 2 helicopters, 3 motorbikes and 4 team cars around.

It wouldn't be difficult to use a water bottle as battery. Just pre-install some wires and connectors to the bottle holder and you can swap a regular bottle with a battery one at will. Wireless recharging tech is also nothing new - it would only require parts to make contact and a bottle could do that easily.

The noise issue is still what makes it unlikely to me. But somehow, I can see this becoming a real cheating tool contender at some point in the future.

 

[veganrob]

I don't think noise is an issue. They are nearly silent, and with the crowd screaming so close to the riders the motor wouldn't be heard.

Has anyone EVER seen the supposed X-Ray machine that the UCI uses ?? does it even exist ?

 

[veganrob]

UCI has done a an admirable job of suppressing bad tests but it is getting harder now. But there is no outside agency to answer to in fiding a doped bike so it is like gold to UCI. They have total control.
One poster mentioned they were x-raying bikes but I doubt it. Besides, how easy would it be to just set up a phony machine. Pretty damn easy. It would take way to long to check all the bikes. Not gonna happen.

I guess it was bought with a donation from Fabian, and as widely used as the mythical SYSMEX machine....
