Sorry, something went wrong while retrieving the video.

Allegations of motorised doping have been fired against Movistar by the Italian media, after a video appears to show the rear wheel of one of their bikes still spinning once the rider had fallen off.

La Gazzetta dello Sport question whether Ion Izagirre’s Canyon bike may have had a hidden motor concealed inside when Spanish rider fell during Wednesday’s opening stage of the Volta a Valenciana.

The suspicion follows last weekend’s revelation that under-23 rider, Femke Van den Driessche, was found to have a motor hidden inside one of her bikes during the Cyclocross World Championships in Belgium.

No rider within the men’s pro tour has ever been found guilty of riding a bike that contains a fitted motor despite claims dating back to 2010 that this practice exists.

However these latest allegations mirror the ones lodged against Ryder Hesjedal in 2014, when in an almost identical incident Hesjedal’s bike moved across the road of its own accord after he fell off.

Movistar faced accusations of mechanical doping at the 2015 Vuelta a España, when a video emerged of a team mechanic allegedly trying to hide a broken bike halfway through a stage.
