Don't bicycle races have inspections? Safety or otherwise? I'm more familiar with motorcycle and car races where there are long lists of "class", safety, and weight requirements. Would be trivial to detect either by weight or looking down seat tube.

they aren't saying how

bikes have minimum weight and can be made lighter than that so weight can be masked

I remember a Kickstarter that was popular that had a bicycle wheel with a motor in it that you could fit most bikes. I'd be far more interested in a solution like this for a daily commute, seems very elegant.

they are readily available

> Here's the thing. No one to date has actually been caught using one. Actually 6 weeks ago Femke Van den Driessche was caught with a motor in the Cyclocross World Championships. The UCI are pushing for a lifetime ban and a very hefty fine for Van den Driessche, so there is a significant disincentive: http://cyclingtips.com/2016/03/uci-seeking-lifetime-ban-and-...

That doesn't matter, the UCI code considers all equipment that a rider or team possesses within the confines of the race area as to be part of the equipment covered by the rules, and every rider and team knows this.

    The presence, within or on the margins of a cycling competition, of a bicycle
    that does not comply with the provisions of article 1.3.010. The use by a
    rider, within or on the margins of a cycling competition, of a bicycle
    that does not comply with the provisions of article 1.3.010. All teams must
    ensure that all their bicycles are in compliance with the provisions of article
    1.3.010. Any presence of a bicycle that does not comply with the provisions of
    article 1.3.010, within or on the margins of a cycling competition, constitutes
    a technological fraud by the team and the rider.
No rider brings into a competition area any equipment that they do not intimately know and they are fully aware that the UCI is going to have access to look at it all. Her excuse that it was a friend's is about as sound as Sharapova's excuse about doping yesterday. Possessing the bike, bringing it into a competition area, mixing it with competition equipment... it makes no difference whether or not anyone proves it was "used" (by any definition), the rules were explicitly clear.

There are two videos on Youtube that have been regarded by bike fans as suspicous. I will let HN readers make their own minds up! https://youtu.be/8Nd13ARuvVE?t=3m35s and https://www.youtube.com/watch?v=ideiS-6gBAc I would love to hear smart people's thoughts!

That second one is either a motor or a flywheel. No way a normal road racing wheelset could spin a fallen bike like that. Just my gut talking, though. I could be wrong...

Rotating a light bike like that takes a lot less energy than you might think. Kinetic energy is also V^2 and the out edge of that wheel is probably doing 30+mph as it's down hill, so IMO it's actually believable.

Granted, it would be much easier to get a motor to do the same thing.

I'm not arguing she's not guilty of something, I'm saying that what the other guy wrote was technically correct.

Is there any way to scan these bikes for EMF radiation?

Not necessary. Just weigh the bike. Racing bikes are very light. Bikes with a motor in them are substantially heavier. Any rider with a suspiciously heavy bike gets extra screening.

Real race bikes are artificially heavier to meet the UCI minimum limits and have been so for many years. It is standard practice to add lead weights to the center of the bottom bracket, for instance in order to 'make weight'.

I'd never would have thought to use a worm ring geared motor hidden in the frame. Reminds me of how nitrous bottles are hidden inside roll cages and cooling systems in racing cars. Cheating is an art of itself.

The favorite nitrous story I heard was the guy that had it hidden in the hood of his car. The first thing they would do during inspection after he was accused would be to remove the hood.

A few other commenters have touched on it, but I'll go ahead and say it -- the UCI really needs to drop the minimum weight limit which I think will be an effective disincentive (along with more draconian life time bans).

They are artificially holding back the state of the art in a way that promotes cheating (if you need to add weight to your bike to make the limit, why not a motor instead of dead weight.)

Here's Cancellara winning Strade Bianche this past Sunday: https://youtu.be/X8YJH23dIAc

I think it looks pretty similar in terms of terrain, style, and effort, and it was a win over a tough field. With all the concern about mechanical doping, they checked his bike and there was no motor in it.

Of course there's no way to know what happened in 2010 for sure, but he has shown he doesn't need a motor.
