What is mechanical doping? IS it really possible to bring a motorbike to a bike race? In light of events at the world championship, we find out.
At the cyclocross world championships in Zolder, Belgium, a rider was – for the first time ever – caught with a motor in their bike.
There have been rumours about this for years, but this is the first time that we've actually seen or heard of hard evidence and a rider getting caught.
