AIGLE, Switzerland (AP) The International Cycling Union says there were no cases of riders using hidden motors inside their bikes on this year's Tour de France.
In a statement Wednesday, the UCI said that 3,773 tests ''using magnetic resistance technology'' were carried out unannounced ''prior, during or after racing, throughout the 21 stages of the (race)'' and that they all came back negative.
A magnetic resistance test is carried out with a tablet computer using software to scan a bike.
It can detect motors, magnets and batteries in a bicycle's frame, wheel hubs and rims in less than 30 seconds.
This testing led to cyclo-cross rider Femke Van Den Driessche of Belgium being caught using a hidden motor at a world championship race. She was banned from cycling for six years in April.
