.
In a statement sent Cyclingnews via email Sunday evening, the governing body said it is confident it currently uses a method of detection that is “extremely efficient.”
““The UCI has been testing for technological fraud for many years, and with the objective of increasing the efficiency of these tests, we have been trialling new methods of detection over the last year,” the UCI said.
“We have looked at thermal imaging, x-ray and ultrasonic testing but by far the most cost effective, reliable and accurate method has proved to be magnetic resonance testing using software we have created in partnership with a company of specialist developers. The scanning is done with a tablet and enables an operator to test the frame and wheels of a bike in less than a minute.”
The magnetic resonance testing was used to detect a hidden motor at the UCI Cyclo-cross World Championships in January at Heusden Zolder, where the UCI says it tested more than 100 bikes.
“We have tested bikes at many races this year (for example 216 at Tour of Flanders, 224 at Paris-Roubaix) and will continue to test heavily in all disciplines throughout the year. Co-operation from teams and riders as we have deployed these extensive tests has been excellent.”
In a report broadcast Sunday evening on France’s Stade 2 and published earlier in the day in the Corriere della Sera newspaper in Italy, Thierry Vildary and Marco Bonarrigo said they used an expensive heat detector to spot hidden motors at both the Strade Bianche race in Tuscany and the Coppi e Bartali stage race.
The two-page article in Corriere della Sera claimed that the heat detector – which was disguised to look a video camera, managed to spot seven different motors being used at Strade Bianche and Coppi e Bartali. Five were hidden in the seat tube, with two hidden in the rear hub and cassette. The newspaper report and Stade 2 video report did not name any riders involved.
Over the winter, the UCI introduced strict rules against what it describes as technological fraud and has carried out regular bike checks at the start of races using a blue tablet teslameter device that apparently detects magnetic fields.
However, the Corriere della Sera article describes the UCI tablet has “not very reliable’.
The UCI disagreed with that claim, however, saying “we are confident that we now have a method of detection that is extremely efficient and easy to deploy.”

quote:The Macau Marathon organizers are considering disqualifying Flomena Chepchirchir, the female runner who won the 2014 race while being banned by the International Association of Athletics Federations (IAAF).
As the Times reported first-hand on Friday April 8, Chepchirchir, a 35-year-old athlete from Kenya, won the 2014 Macau International Marathon while she was banned for doping. The long-distance Kenyan female runner was in the middle of a ban period decreed by IAAF after testing positive for a controlled substance at the Birell Prague Grand Prix Marathon, Czech Republic, on September 6, 2014. According to IAAF News Issue 159, the athlete was banned from competing for a 6-month period between September 6, 2014 and March 3, 2015.
Replying to questions posed by the Times, the Sports Bureau (ID) said that it “discovered in January 2015 via news that Flomena Chepchirchir might have participated in the 2014 Macau International Marathon while serving a ban given by IAAF.”
“Since the discovery of the issue, the Organizing Committee had immediately written to IAAF to seek confirmation and further information on the issue. But to date IAAF, has yet to provide an official reply and provide us confirmation of Ms Chepchirchir’s case,” ID stated.
The bureau also says that besides seeking conformation from IAAF, they have also tried to contact Chepchirchir’s agent who suggested that the runner was intending to appeal the IAAF’s ban.
The bureau’s statement adds that “pending the outcome of the case, retrospective action would be taken to disqualify” the Kenyan athlete and “adjust the results of the runners who finished in subsequent positions accordingly.”
According to the ID, Flomena Chepchirchir was asked to perform an anti-doping test after the conclusion of the Macau Marathon. She tested negative.
ID stated that the local marathon organizing committee “takes the issue of anti-doping in sports very seriously and we have always had a standard procedure and performed thorough checks to ensure the participating athletes are eligible to take part in our competition,” highlighting that Chepchirchir’s case was “isolated.” However, it is stressed that the case shows “there are still improvements to be made to our checking procedure, and in the future, we intend to seek more proactive communications and collaboration with international federations […] in order to prevent similar issues from happening in the future.”
sports bureau reply to the times
“The Organizing Committee discovered in January 2015 via news that Ms. Flomena Chepchirchir might have participated in the 2014 Macau International Marathon while serving a ban given by IAAF for the effective period from 6 September 2014 to 5 March 2015. Since the discovery of the issue, the Organizing Committee has immediately written to IAAF to seek confirmation and further information on the issue, but to date IAAF has yet to provide us an official reply and provide us confirmation of Ms. Chepchirchir’s case. We have also been in touch with the representing agent of Ms. Chepchirchir to seek clarification of the situation, and we were advised that they were intending to appeal to IAAF against the ban.
Pending on the outcome of the case, retrospective action would be taken to disqualify Ms. Chepchirchir’s result in the 2014 Macao International Marathon and adjust the results of the runners finished in subsequent positions accordingly if it is confirmed that Ms. Chepchirchir should have been banned from running in the 2014 Macau International Marathon.
Elite runners from all over the world have participated in the Macao International Marathon. For all invited athletes who participate in the Macau International Marathon, including Ms. Chepchirchir in 2014, the Organizing Committee perform a standard and thorough procedure to check if any of the athletes are serving bans imposed by IAAF before they are allowed to run in the race. At the time of the 2014 Macau International Marathon, there was no information from IAAF that Ms. Chepchirchir was ineligible to run in competitions hence her registration for the event was approved.
After the conclusion of the event, an anti-doping test was also performed on Ms. Chepchirchir and the result was negative. As Ms. Chepchirchir’s case only came to light in January 2015, the Organizing Committee could not have prevented her participation in the 2014 Macau International Marathon.
Taking this opportunity, we would like to emphasize the Organizing Committee takes the issue of anti-doping in sports very seriously and we have always had a standard procedure and performed thorough checks to ensure the participating athletes are eligible to take part in our competition. However, Ms. Chepchirchir’s isolated case highlighted that there are still improvements to be made to our checking procedure, and in the future we intend to seek more proactive communications and collaboration with international federations such as IAAF to ensure all participants in the major sporting events are eligible to take part so that we can prevent similar issues from happening in the future.”
quote:De discussie over mechanische doping kwam in een stroomversnelling nadat veldrijdster Femke van den Driessche op het WK tegen de lamp liep. “Zij gebruikte de eerste generatie motortjes”, legt Wathelet uit. “De motortjes die vandaag bestaan zijn veel duurder en veel geavanceerder. Ze werden oorspronkelijk gebruik in de ruimtevaart en zijn dus zeer krachtig en duurzaam, maar ook kostbaar. Ze kunnen zelfs worden aangestuurd door het ritme van je hart. Zo kan de motor helpen wanneer je een bepaald ritme overschrijdt.”

quote:Although 2010 is the year when the rumours about hidden motors first surfaced, Philippe Gilbert’s agent has said that he believes the machines may have been in use much longer than that.
“A very long time ago, Stefano Varjas [the Hungarian engineer believed to have been behind the most sophisticated motors] approached one of the riders that I am very close to,” said Vincent Wathelet to RTBF.be. “[He was] saying he had lost many races compared to competitors who used electric bikes.
“What we see in the report [the Stade 2 TV programme broadcast on Sunday – ed.], he had already shown him three years ago. I then contacted the engineer. I asked him for an explanation. I fitted out a bike with all these prohibited things in order to demonstrate to the UCI that it exists and that it is used.”
Wathelet said that the bike has been used in numerous youth races but also amongst the professionals. “We speak a lot of 2010, but I have evidence that it was in the peloton for much longer than that.”
Wathelet represents Gilbert as well as others such as Arnaud Démare and Boris Vallée He is also a TV producer of cycling races. He said that he has been trying to alert the UCI to the problem for a long time, both in relation to road racing and also to cyclocross.
The first ever confirmed case of a motorised bike being at a top level competition occurred in January when a spare machine in the pit area of the Belgian rider Femke Van den Driessche was found at the world cyclo cross championships. A verdict is expected soon in that case.
Wathelet said that he had made reports on the motorised doping issue to Umberto Langellotti, the president of the cycling federation in Monaco. He said that Langellotti was instrumental in getting the UCI to raise the sanctioning penalty in relation to the issue.
“At the time, a rider who was caught with a mechanical or electrical assistance risked a fine of 100 Swiss francs. It was so absurd. Fortunately, in 2014, the UCI regulations evolved.”
He gives a little more detail about what happened six years ago. “I hope that this case [the Stade 2 report] will make the cheaters think and that we will have the means to fight effectively. When you see that in 2010 some very famous riders carried their bikes in their hotel room and slept next to them, you ask a lot of questions because it is neither the purpose, nor the practice, in our profession.”
New detection methods needed
The UCI has said that it is tackling the issue as well as it could but Wathelet is not convinced. “I complained many times to the leadership [in previously years]. I said that controls were inadequate, that the UCI scanner was a toy, that it really does not allow them to effectively control.
“Remember these scanners that we saw happen in 2011 and 2012. They did not have the ability to check additional sources of heat and energy.”
The Stade 2 investigation used the kind of thermal imaging cameras that Greg LeMond has been calling for. Speaking to CyclingTips earlier this year, LeMond said that he believed the UCI’s method of measuring magnetic resistance was not enough to detect every type of hidden motor.
Wathelet urges the governing body to expand the systems used. “Thermal imaging cameras are the only way to demonstrate that indeed a bike delivers a source of abnormal energy, which is not a friction that comes from use of batteries.
“The current control system, finally arrived in cyclocross at the initiative of a Belgian officer [Walloon cycling federation president Thierry Marshal – ed.] allowed the catching of Femke Van den Driessche at the world cyclocross championship in Zolder. But I must say she used the first generation of engines.”
He said that such a system costs 7,500 euro and that 1350 were sold in 2015. However he believes that far more sophisticated motors are now available. [According to Stade 2, one such system uses electromagnets hidden in wheels – ed.]
“Basically, they are used in aerospace to open the shutters of a satellite when it is launched into orbit, so you can imagine how these engines are durable and powerful,” he said. “It also means that these type of materials that cost a lot of money are not easily recognizable in a scanner.”
Watching out for suspicious finger movement, as was red-flagged in the past as one possible sign of turning on a motor, is something he says is no longer relevant.
“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.”
Asked how to pinpoint those who are cheating, he said that both performances and physical parameters must be considered. “When you find an incredible pedalling pace in a slope at high altitude with low heartbeat, in my opinion, it is clear that there is cheating.
“It is a rule of three [factors]…the heart beat, the rhythm of pedalling and the slope. But as I said, it’s not sufficient [to form conclusions in this way – ed.] it is also necessary, in this case, that all legal mechanisms are put in place that the bike is seized, that the spare bikes are seized, and that mechanics don’t have the chance to approach the bikes.
“It is also necessary that in the future we forbid changing bikes except for serious mechanical reasons.”
