The UCI checked the bikes used by the medallists at this weekend's cyclo-cross World Championships for the presence of motors but found nothing. It was the first time that the federation scanned bikes after claims made by Danilo Di Luca that the use of motors would be possible.

Danilo Di Luca attracted much attention when he gave a much-discussed interview on Italian television, making several claims about doping in the peloton. One of his claims was that it would be entirely possible for a bike rider to use a motor in the professional races.

Whether it happened in response to Di Luca's claims or on their own initiative is unknown but the UCI decided to check the bikes used by the medallists at this weekend's cyclo-cross Worlds for the presence of motors. According to Het Nieuwsblad, UCI officials removed the saddles from the bikes and used a camera to check inside the seat posts for the presence of motors but nothing was found.

Di Luca's comments are not the first to start a discussion about the use of motors. After his dominant ride in the 2010 Tour of Flanders and Paris-Roubaix, Fabian Cancellara was accused of using mechanical assistance to take his wins in the big classics.

Cancellara firmly denied the claims but the UCI decided to scan bikes at that year's Tour de France. Nothing was found and since then, there has not been much talk about motors in the peloton.
