The UCI has announced that officials carried out checks for mechanical doping on the bikes of ten teams (Orica-GreenEdge, Lampre-Merida, Wanty-Groupe Gobert, Direct Energie, Cannondale, Movistar, Ag2r-La Mondiale and Delko-Marseille) at the start of Paris-Roubaix.

They used tablets to check race bikes lined up at the team buses as well as spare bikes on top of the team cars. According to Cyclingnews, UCI officials used the blue tablet to check frames, cranks and wheels of each bike.

The UCI confirmed that 196 bikes were checked, plus 27 bikes from the Junior race that finished a few hours before the men's race. 

Cyclocross racer Femke van den Driessche put bike racing in the news. The Belgian athlete has the dubious distinction of being the first rider accused of “technological fraud,” or mechanical doping, after a hidden motor was discovered in one of her spare bikes at the 2016 UCI Cyclocross World Championships.
