War on Hidden Motors Goes Undercover

The International Cycling Union (UCI) is enhancing its efforts to detect and prevent "mechanical doping," which involves using concealed motors in bikes. This action follows a 2010 incident where a Belgian cyclist was banned for using a hidden motor. Advances in technology are making these motors smaller and lighter, thus more difficult to find. The UCI acknowledges the ongoing challenge as a "technological arms race" against increasingly sophisticated cheating methods.
