Headshot Posted June 1, 2010 Share The system they show being fited to a tourer could have been adapted but where to put all the batteries. A brushelss motor runs far longer than a brushed kind on a given battery supply but still... I'd have liked to see a better expose on that carbon race bike they show.

Wyatt Earp Posted June 1, 2010 Share A brushelss motor runs far longer than a brushed kind on a given battery supply Not really that much longer and you would have to use lipo batteries. Besides, with the diameter of the actual unit being thicker than the bike's actual seat tube, is enough reason for me to find this a joke. Link to comment Share on other sites More sharing options...

MaxUmis Posted June 1, 2010 Share I don't think it's a question of whether it can be done, but rather if he did it. He won't need to run the motor for the whole race; only when he needs it. so 5 x 18650's with a 2.5A draw will supply close to 50Watt of electrical power... Put 50Watt ontop of what those athletes push into the pedals and you'll find that 50Watt is a big bump in power. Remember that if they did it, it' wouldn't have been a home hack job, so they could easily hide the batteries in the top/down tube with no external cables.

Wolweseun Posted June 1, 2010 Share I do love a good conspiracy theory!This one does have me sitting the fence though.... It's true because:- My first impression of Sparty's acceleration and subsequent motorbike TT was that it was too good to be true. The guy absolutely smashed the world best cyclists (including past winners).- A wee motor like that one can produce about 200 watts for one hour - enough to ride a 40km TT at rididuclous speed. It's false because:- It's just too flipping obvious! The motor noise' date=' the extra weight, the extra little buttons on the gear levers - someone MUST have spotted it. Especially because there is a strong cycling paparazzi who specialise in spotting new gadgets - especially at unique races like Paris-Roubaix. I guess I think it's false - but my mind can't stop saying "what if!!!".[/quote'] 200w is a pathetically low power output for a Pro Rider Even I can sustain a lot higher power than that for an Hour Link to comment Share on other sites More sharing options...
Martin PJ Posted June 1, 2010 Share If it is technically possible, then someone is doing it. If I had 50 extra watts throughout the local races, I could ride with the pros. Floyd Landis could maintain 350 watts at threshold, Tom Boonen 420 watts. 50 watts is all the difference between the average pro and the elite.

Lucky Luke. Posted June 1, 2010 Share 200w is a pathetically low power output for a Pro Rider Even I can sustain a lot higher power than that for an Hour The idea is not to stop pedaling and free wheel to victory. Cancellara is already putting out 400+ watts. Add 200 to that and his power to weight ratio becomes somewhat ridiculous. This whole story is pretty ridiculous too though.. imagine if it's true! hahaha Here's an English summary of what the Rai journalist is saying:http://theinnerring.blogspot.com/2010/05/electric-bikes-are-in-peloton.html Link to comment Share on other sites More sharing options...
Wolweseun Posted June 1, 2010 Share If he is generating 400w and is using a 200w motor the 200w motor would probably slow him down A few years ago his avererge power output on the TDF Prologue was 540W Cancelara is a machine get used to it (not a mechanical one either) Link to comment Share on other sites More sharing options...
Woofie Posted June 1, 2010 Share It could be true. At the end of the day even if it only provided 20 extra watts of power to the pedals it will make a big difference over the hour. A motor that size and a small lipo battery pack could be hidden away so so easily in the downtube. Small remote controlled switch could easily be consealed in the bars and under the tape. They are building bikes so so light that they could have easily chopped and changed some components to get the bike back to the 6.8kg even with the battery and motor. Maybe they should even start making motors an optional thing? Imagine the kind of technology that would come out of that in a few years. It would be the commuters ultimate dream. It would also add a extra twist onto road cycling, making it even faster and more entertaining. Link to comment Share on other sites More sharing options...

Anyhow the whole story is pretty unbelievable. I'm not trying to lend it any credence, but you have to admit it's pretty funny. Not to mention the name - 'motorised doping' - as if any kind of cheating is now a form of doping. Theo Bos chucking Daryl Impey into the barriers at Tour of Turkey - would that be rope-a-doping?

Headshot Posted June 1, 2010 Share And heres a link to the conversion system http://www.gruberassist.com/category/englisch/ I see a comment on another forum mentioning that a pro cyclist had claimed that Cancelara's bike had made a strange whirring noise during another race.
