After much speculation on the subject, the day has come: a professional rider has been found in possession of a bike subjected to "motorized doping", i.e. featuring a concealed motor in the frame. The incident occurred at yesterday's Cyclocross World Championships, where 19-year old Femke Van den Driessche's bike was discovered with cables coming out of the seat tube and a motor concealed in the BB area.Femke Van Den Driessche (Belgium) winning the women's U23 European championship (Bettini)Speaking at a news conference today, UCI boss Brian Cookson said “It is no secret that a motor was found, we believe that it was indeed technological doping. Throughout the 2015 season, we carried out unannounced bike checks at major road events and we will conduct similar controls throughout the 2016 season, we have introduced in 2015 a set of Regulations that enables us to take action, and we’ve been trialling new methods of detection but you’ll understand why I don’t want to go into details of those methods."The rider accused is denying any wrongdoing, as reported today on Cyclingnews "I didn’t know anything about it. I don’t know how that bike got there. I was surprised to see that bike standing there. It’s not my bike. There’s been a mistake,” she told the Belgian broadcaster Sporza. “There was nothing in the bike that I used at the start of the race. I train hard for it too, you know. Then it’s no fun to be accused like this.“If I would’ve been on a bike like that I would’ve been more consistent. I’ve always peaked towards those moments. I worked really hard for it. I haven’t got anything to say about it but it’s really terrible.”Van den Driessche offered up a potential reason for the bike’s presence, saying that it was owned by someone she’d been training with. “That bike belongs to a friend of mine,” she said. “He trains along with us. He joined my brothers and my father. That friend joined my brother at the reconnaissance and he placed the bike against the truck but it’s identical to mine. Last year he bought it from me. My mechanics have cleaned the bike and put it in the truck. They must’ve thought that it was my bike. I don’t know how it happened.”The UCI reportedly implemented a new scanning technology to detect this kind of cheating at this very race. If the first race they try it at reveals a cheater, what does that say for racing in general? Could motors already have been used in MTB races? In light of the history of doping and cheating, it would be foolish to assume not...Femke now faces a suspension of minimum 6 months and a fine of 20,000 to 200,000 Swiss Francs (approximately the same amount in USD). We'll monitor the story further as it develops.
