Wow, wow, wow!

Denial ain't just river in Egypt. I'm just floored. I shouldn't be. But I am.

I still don't get the rim magnets thing.

lsd, I think they work something like this: You have (say) 4 magnets in the rim, spaced equally. In the seat tube under the seatpost is wiring that can be activated to become magnetic or turned off. The wiring pulses, turning on as the magnet approaches the rear brake, then off as it passed by the wiring. So each "on" pulse pulls the top of the rim forward. No moving parts, no noise.

So should be easily detected with the bike at the start line.
And they have to lug that extra rotational weight, which is not infinitesimally trivial like a disc rotor - these magnets are way out peripherally.
So I still don't get the rim magnets thing - for a long road race.

I am hereby declaring the term "mechanical doping" null and void.
Henceforth we shall call it as it really is, "Some arsehole racing a motorcycle in a bike race"
Yes, it's more cumbersome to say but its accuracy cannot be dismissed.

I can definitely feel the difference with heavier vs. lighter tires. But I can feel a lot more of a difference, when back in junior racing days, I'd get a brief push to stay on the pace line. Those wattage numbers they're throwing around seem to me more akin to a push, than even rotating weight.

Another fan of heat guns, Gianni Bugno, ex-pro, now a pilot who scans power lines with a heat gun looking for problems.

http://www.cyclingnews.com/news/bugno-calls-on-uci-to-use-heat-cameras-to-detect-mechanical-doping/

The best part of using heat guns is that they are real time, ie showing what is actually happening on the course. Swapping bikes to avoid detection doesn't work. That recorded heat signature (assuming you simultaneously video record the rider's number) would be all you would need. Of course, this would lead to a bigger problem for UCI, conceding that Greg Lemond was right.

But not on all the time. There is only so much energy in a battery.

Yeah, each cheating rider has probably an hour or less of juice. But say you had 4 guns on the course. One of two on the big climb or climbs. A couple located at a random points. That would make using your motor pretty risky.

Edit: and of course, you could have one on an accompanying motorcycle.  That would put a real damper on use.

A lifetime ban for the first offense is warranted.

Come on people, quit ruining my favorite sport!

Yeah, after Flanders and Roubaix, I was kind of loving the sport again. Then I read about that masters d!ck in california and scanned through the motor stuff yesterday and am ready to turn it off for the summer.

The best part of season is over anyways. Amstel Gold was fairly brutal to watch. http://velonews.competitor.com/2016/04/news/the-calm-after-the-storm_402425

Another interesting angle...

“This material can be triggered by your heart beats when you exceed a certain heart rate. In general, the limit is 160 beats which allows you to recover while your engine compensates. But like everything which is miniaturized, it is very difficult to detect.”

Six year ban... not sufficient. Lifetime
