Subpage under development, new version coming soon!
Subject: Giro d'Italia
in a few days, the tour de france :P
Go Contador!! ^^
Go Contador!! ^^
you think? If they do it wouldn't be nice to watch cycling on television, those motors make a lot of noise.
Do they really? It's electric, I think they would be very silent.
In 1st part of the video, Cassani show us how it work, and it doesn't seem very loud to me ;)
How is this plausible? What next?
Do they find a motor in Bolts unterpants?
Or a ball magnet in federers racket? :P
Or little green aliens in Czech Icehockey-team.

Silly counter arguments doesn't make it less plausible ....
I see electrical motors all around me, to make 1 fit in a bike isn't even a challenge for the best bikebuilders in the world, I'm sure about that. So show some evidence it isn't plausible at all, that would be real prove.

At minute 1.20, Fabretti asks Cassani what could be the top speed of this bike. Cassani answered 60Km/h (the subtitels says 50Km/h, but Cassani says 60!) in plain!!!
1) An electrical motor isn't soundless.
2) Other riders would notice if there was a special "button" under (or wherever) his handlebar.
3) Additional weight.
4) High possibility of damage -> additional weight for nothing. Makes less sense in races with cobblestones.
I once saw a whole list of arguments against it but I can't find the link anymore and I don't have time to search it.

almost...

I challenge you to watch the video and say "here!!! here we can see the button!!!". It's very easy to think the button purpose is to change gear.
3) Additional weight.
Bicycles as a minumum weight of about 6.8 Kg, but builder could make bicycles lighter than 3/4 Kg, so the motor's weight isn't important
4) High possibility of damage -> additional weight for nothing. Makes less sense in races with cobblestones.
I don't get the point. Are you suggesting could be more usefull to have a slower bicycle?

I didn't see any button btw ;-)
And if there were any, I'm sure other riders/managers would say anything!

No, I'm saying that if it doesn't work it's even harder to ride the bike ;-)
And here I found a very good video where Cancellara - and some others - describe his bike, his performance etc. I don't know if you can watch the video because it's from the Swiss TV and I think it can only be watched in Switzerland. And if you watch it, it's in Swiss anyway ...

But it analyzes different things, for examples Cancellaras "power bursts". They measured his pedal frequency and his performance and they showed that even if you don't see anything Cancellara is able to accelerate due to his pedal frequency.

Here is a pretty good reason in my opinion:
Cancellara din almost 50 km in those 2 races after he got in front. For that period of time, he had almost the same rithm and speed. To have such an electrical motor powered by batteries for so long, you either need a lot of batteries, or new technologies just discovered. As i don't think the team or bike manufacturer discovered new battery technology, he needs a lot of batteries. And batteries are heavy-very heavy. Just as comparison: almost all the weight in your cell phone is the acumulator. The battery for a laptop has about 600 grams. This are examples of low power batteries, with which you can't drive a motor.
To provide power for about 1h for an electric motor that could actually help you cycle I think you need something similar to a car battery. And those are heavy, way over the 7 kg limit of the bike.
So it's not the motor itself that makes this thing BS, but the way to give power to that engine.

Unless the battery is powered with the movement of wheels...
anyway it wasn't said that he uses it all the time - just let's say when he is having a power crisis and needs some 'time off'.
