Mechanical doping

[1] Four years later the issue was raised again when Ryder Hesjedal was the subject of allegations of mechanical doping during the 2014 Vuelta a España: Hesjedal crashed on stage seven of the race, and video footage of the crash showed his bicycle's rear wheel continuing to spin after it had fallen onto the road, leading to a number of media outlets including the website of French sports newspaper L'Equipe questioning whether the bike contained a motor, although it was suggested by Cycling Weekly that the bicycle's movement could have simply been due to it sliding on a downward gradient.

[2] Public pressure on the UCI led to the race commissaires examining the bikes of Hesjedal's Garmin–Sharp team the following morning: no motors were found.

[9] Van den Driessche and her accomplice broke an eight year silence to speak with the podcast series Ghost in the Machine[10] in 2024, revealing that they had experienced death threats, closed down their business and were forced to flee Belgium for their safety.

[12] In May 2010 former rider Davide Cassani demonstrated a motorised bicycle on the Italian public broadcaster RAI, claiming that similar bikes had been used by some professional cyclists since 2004.

[23] In March 2018, the UCI announced that X-ray cameras would be used in future on Grand Tour stages and classic cycle races, to detect the use of hidden motors.
