‘Technological fraud’ discovered at Zolder cyclocross worlds

One thing I find interesting, for road cycling at least, is that the UCI mandated weight minimums could make it easier for a rider to attempt something like this. Many of the bikes need weights in the seat tubes to bring them up to the minimum weight, so the extra weight of a motor and battery wouldn't stick out as much. If they were to lower the 6.8kg minimum, a bike with motor and battery might end up weighing noticeably more than the average bike in the peloton.
From Cancellara's Paris-Roubaix acceleration [1] to Ryder Hesjedal's [2] bike "moving on it's own", to even Chris Froome [3] Tour accusation it's been getting heated at the top levels.
The UCI introduced mobile scanning machines in 2010 [4] and this would be the first actual confirmed case.

tbh it hasn't done him much good results wise, unless he was using it in the Giro 2012
The scanning is simply going to have to become pervasive.
Manufacturers have used the "spare" weight for aero purposes - deep wheel rims, profiled tubing etc. The incentive to shave off grams is just as strong. Every gram saved by skimping on strength is a gram that can be used to reduce drag.
Safety has been dealt with by the certification scheme for frames and wheels. Every frame and wheelset used in a UCI sanctioned race has to be tested to UCI standards, so the weight is academic.
The technical playing field is far from level and costs have never been higher. The leading WorldTour teams can afford a lot of technology that's out of reach for Continental teams. Two aero bikes, two climbing bikes, a classics bike, a TT bike, eight different wheelsets, plus wind tunnel time to get it all working - that easily adds up to $100k per rider.
Also note that frame efficiency is more important than its weight. For instance there were silly light, silly expensive bikes around which had crap performance, because they twisted like noodles in the wrong places.
Super light weight is a great magnet for dentists.
What is the benefit supposed to be of getting hit by a heavier bike?
There's an argument to be made that the technology has improved, and that the limit could be lowered.
[1] A component which has had its strength and durability compromised in the interest of saving weight.
Weight minimums are good for keeping a level playing field by keeping the cost to entry "low" by keeping it to the thousands.
There are no bikes in the in the World Tour peleton that retail for under $10,000. You can easily build a sub 6.8kg bike for that.
They're also good for safety reasons, both for the rider and others they might crash into; there's no incentive to try to cut too much weight in a way that could impact safety if there's a weight floor anyway.
There's some truth in that, but the limit is way, way lower than where it is at the moment. The fact that weights are being added to push bikes over the limit has no safety impact.

AUD $4,300 - eek!
I think they get much more widespread adoption when the systems get lighter and cheaper.

this said anecdotally I am seeing more and more people on e-bikes here in North America too, bike commuting every day these days at least a few times a week I get passed by somebody riding one of them, did not happen at all until a few years back
the other thing: a change in chainrings and cassette makes a much larger difference in "ease of pedaling" than a fancy carbon frame. if you buy a fancy carbon frame and carbon wheels the reason is to go faster while suffering just as much. want a easier time getting up hills, slap a mtn triple crankset, long reach derailleur, and wide cassette on your clunker. now you can exert yourself as little as you want and you spent $150 instead of $2000.
eBikes are readily available in all sorts of styles, some can set you back $5000
Stuff like that happens a lot when taking a bidon from a car, or when talking to a doctor and is somewhat accepted, but this was deemed to be excessive.
To me, this fragment isn't that clear. Yes, he easily gets out of the group, but the others seem to slow down a bit, and he had more ambition to get back to the leading group because he was aiming for the overall win of the race. Also, he was the better rider in that group, and camera angle doesn't help.
He (for a large part thanks to hard work by his teammates) did manage to return to the leading group, though, and many in that leading group would have kept the speed high because they knew an important contender for the overall win was behind.

This said I wonder what principle(s) the "handheld detector" was operating under, maybe it could detect the winding(s) of the electrical motor via inductance or something?
This sort of high-tech cheating reminds me of Smokey Yunick's various tricks ( https://en.wikipedia.org/wiki/Smokey_Yunick )
Oh yeah? I can't imagine such a cheat would pass overhead of the coach. It feels like VW executives saying it was a couple of zealous engineers..
For example, Lance Armstrong's "coach" Chris Carmichael (notoriously) had little to do with his training (Michelle Ferrari developed his training programs). Carmichael probably knew about his drug use, but it's likely there are plenty of other similar cases where a national coach had even less contact.
"National Coach" is often more akin to a manager/selector role.
Notably, in this case her father was her trainer. Apparently her brother is currently serving a suspension for EPO use[1].

How much advantage can that provide, after taking into consideration the extra weight?
“This model has three settings,” he explained. “It produces between 50 to 75 watts for about an hour and a half, does 150 watts for an hour and in its highest setting, produces 250 watts for up to 30 minutes."
It can provide a substantial advantage at the high levels of competition.

250W for 30 minutes is more than most non-racing recreational cyclists can manage.
Shimano, Campagnolo and SRAM all make batteries designed to fit in the seat tube for electronic gear shifting.
Electronic shifting uses almost no power; the derailleur just has to periodically move a few millimeters. There's absolutely no comparison.
In total, there is "plenty of room in a frame" and so it's probably theoretically doable, it would just require much more work to pack it with cells and wire everything up. The companies currently making these motor kits are probably using off-the-shelf battery packs.
Maybe you're right, though, that a smaller battery providing "bursts of power" would be enough to make a difference though.
In something like cyclocross, the difference from a frame motor would probably be even bigger. The races are shorter (60 minutes vs 4-6 hours) and the power bursts are short and intense - power through a mud pit, stay on bike instead of running a super steep hill, etc.
Here's a 4kW (more than 5HP!) motor that's less than 5cm in diameter and 10cm long:

One problem with fitting these into a bike is that they require plenty of active cooling to not overheat, but it shows that such power densities are definitely possible. Especially if for intermittent use with long periods of cooling. 4kW is also extreme overkill if all you're after is a small competitive advantage. As for batteries, 250W for 30 minutes is 125Wh, around the same energy as a typical 9-cell laptop battery.
It appears this type of bicycle motor can maintain 250 Watts for around 30 minutes.
Bottom line - it can make a massive difference to a cyclist performance.
We'll see soon enough. With the amount of cameras and witnesses around it shouldn't be too hard to get to the bottom of this.
It will be interesting to see how the battery was hidden.

She's a fast cyclist. The pace rider who trains with her may need some assistance.
However, that bike should have been painted bright pink so that it was obviously not a compliant race bike.
I don't understand. Are you suggesting that's what I'm implying?
> Why would someone "on her team, who sometimes trains with her" have such a bike?
Because it's a bike from a previous season she sold to them (a well known practice that even pro teams engage in to make some money on the side from bikes they get from sponsors), and they added the motor? And it's not someone on her team.
> It seems quite clear that either there was cheating, or a very inventive attempt to frame her.
There's no logical necessity for choosing only those two scenarios. Here's another one: some guy bought an old bike of hers, added a motor so he could seem like a tough guy (in case he kept it secret), and it got mistaken for one of her bikes.
> Van den Driessche was eventually forced off her bike on the final lap when she was struck by mechanical problems and ended up walking with her bike. Her bike was taken for inspection along with several other bikes after the race. It gives Van den Driessche the dubious honour of being the first rider to be discovered to be using a motor.
Which is slightly different to yesterday when it was reported as being discovered in the pits.
But I really don't know or care enough about sports to defend this position.
Also, I'm 99% sure the NFL's world is about to come crashing down when there is some sort of forced acknowledgement of how many players are taking HGH
Cycling can't seem to decide whether it's a clean contest of human performance or a contest of artificial performance enhancement.
