Another suspected ebike cheater

When the day comes when E-bike races happen professionally...there will be cheaters too.
Someone will have an extra battery hidden pushing there 52v class bike at 72v or something.
There will always be someone who wants a trophy more than the experience of earning it.
 
There is a saying in NASCAR (the most American of motorsports) that "if you ain't cheatin', you ain't tryin'"...... In the end it is more about the financial rewards that accompany a trophy than the tinware. If that's your full time job and your income depends upon a good race finish and you have no other life skills, well, the pressure can be enormous. At least in this case no ones health was jeopardized with weird drugs and medical processes.

Hehe... That writer, an electric motor is not a "real actual motor".
 
Any further info on the "electromagnetic wheels"?

This is the most important part of the story. If one was not trying to hide the system/cheat, there is great potential here. Putting the motor in the rim gives great torque advantages over a hub motor and I can see this concept being developed further..... It won't cost €200000 for very long, I am sure much of that number includes the payoff for keeping it all secret.
 
Possibility to build a carbon deep dish rim with imbedded copper PCB type foil conductors coils in the matrix without iron. Would possibly be a low weight low power setup that is relatively economical / efficient use of materials. Would be a interesting way to get a low power setup for certain. The 200k wheel motor in the article is in the 60 - 100 watt output range. Hardly worth it unless you were trying to hide it completely which should not be promoted in any fashion IMO.
 
Next they will hide the motor inside the rider. Motorized hips and knees, soon they will have to add X ray to dope tests. Cheating is so common now, that I would not be surprized to see competitions to crown the world best cheater. :D
 
so...electromag wheel...
They say they need the magnets close to the wheel...
...why not hide them in the brake caliper, magnetic brake pads?
 
Lots of chatter on the mechanical doping but few clues have yet to be confirmed. No one sure how they have spotted the motor signatures either and more developments in the works. Looks like they may be using some sort of radio frequency detection on running bikes! Not sure if they are looking for controller signals or just rotating mag fields. They claim to be able to check in the pits also. Any Ideas on what could be going on?

van den Dreissches was on a watch list going by some reports before the start of the race. Not at all sure it was not just a tip that caught her.
 
Thermal imaging is very sensitive these days, and I'm sure I read a comment about doing temperature testing.
It should be pretty easy to pick up even minor temp increase in either a motor or a battery, especially as they cannot be getting much cooling enclosed in a bike frame.!

They took her bike from the pits.
Since they say a tablet was used, maybe the motor's controller was showing up on the list of Bluetooth devices or something like that?
 
Certain they will try a variety of detection methods now that they confirmed a cheater at worlds. Will thermal be able to detect a cold system in a pit bike? Certainly it would be able to see hot spots from running components. Not sure how easy it could pick one out of a massive group of riders, but you certainly could not hide a motor system easily once warmed up and suspicions arise. Wheel (Rim) motor may camo better with rim brakes possibly masking heat from braking action.

Advantage of a thermal imager, is you could put officials at random on parts of the course where a motor would be most advantageous (critical climbs, sprint zones, etc) almost inconspicuously, and just scan (and record !). all passing bikes.
Warm motors, batteries,, controllers, etc, would show up easy.
...and they don't use brakes much on climbs or sprint sections !
This is common , proven, industrial technology, used daily for fault finding electrical systems.
If they are not using IR imagers , I would wonder why not ?
....but of course that assumes they actually do want to detect ALL the Ebikes in the comps ! :shock:
 
Thermal imagers are common enough that they could be used in mass for certain. Many adapt to smart phones.
