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

Easier than that, simply X-Ray the bikes at the finish line. Don't even announce which races will do it, that way partial enforcement can work.

That's now going to be necessary. It's not hard; my horse vet has a hand-held X-ray machine and a detection plate that connects to a laptop. An electric motor is obvious in X-rays. It would take maybe 5 minutes per bike. You only need to scan the leaders, of course.

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!

Here's the thing. No one to date has actually been caught using one. The banned woman was caught having one, on a spare bike in the pit. She claims it's owned by a friend (who corroborated) and that her mechanics mistakenly put it in the pit, etc.. it's a pretty shaky story, but the fact remains they have never actually caught someone using one during a race. There's a large number of people who think it just wouldn'…

On a long climb, timed right as part of an attack, it would definitely, definitely be a help. The difference between the top riders is so slim that it would without question make a difference, in my mind.

I think the Cancellara video looks odd, but he is super-human...

The Hesjedal video is just super weird. He could have knocked the motor on during the fall. He also gets up in a really suspicious manner IMO...

Racing bikes are wired to track cadence and speed already which is perfectly legal. These signals are sent to an attached computer on the bike. I don't know if you'd be able to separate out that signal.

For cadence and speed, they are very rarely "wired" anymore. Almost all use ANT+ for communication, it's a very low power protocol meant for low power usage.

Electronic shifting (Other than SRAM's newest) is however wired, but again it's a very low power protocol. It also uses two motors to perform the shifts, but they are very small and external.

I would imagine you could tell the difference and find what you're looking for with something as simple as this: http://www.amazon.com/Fluke-LVD1-Volt-Light/dp/B000B64ZDG

I used to use one for electrical work, and it worked very well.

Why don't they just weigh the bikes? Website states the motor weigh's 1.8kg, that would be easy to detect surely? The component spec for the bikes of a race team are probably fairly fixed, so shouldn't be hard to figure out what a bike should weigh?

A weight minimum is enforced for these bikes, which isn't really close to the possible minimum. It would be trivial to swap different components out for lighter versions in order to accommodate a motor.

By the way, have you seen this? I think it just came out a week or two ago.. https://www.youtube.com/watch?v=Wv5F5N6mFf0

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.

Yeah. Kickstarter has had a lot of interesting bikes in the last year. One YC company, Vanhawks (http://vanhawks.com/), came up through Kickstarter, and they've been shipping smart bikes in the last couple months.

Still, prices among electrically assisted bikes remain high. For example, the Faraday electric bike: https://www.kickstarter.com/projects/faradaybikes/faraday-co... starts at $2,700. It seems like they should be less expensive, but for whatever reason few electric bikes have appeared in the U.S. for under $2K.

It seems like price is holding back electric bikes more than anything else. The system discussed in the original article appears to be much more expensive than an entire electric bike.

The UCI limits the minimum weight a bike must weigh. Carbon bikes and parts can get a bike well below that minimum weight, such that some racers have had to tape weights to the bike to get it up to weight when it didn't pass tech inspection.

Now what if instead of taping weights to the bike...

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.

Me too, it would make biking to work in the summer a little less sweaty, which would make the co-workers happy.

Of course you could just get a motor cycle. I bet the reason you started ride to work had something to do with staying healthy.
