Fabian Cancellara has come out defendng himself against speculation that he used a hidden motor to help him take his recent major victories on the eve of this year’s Tour de Suisse.

“I know how I achieved my wins. I have an engine, but it’s in my body. This is the strongest one you can imagine. Over the last decade I’ve shown that I don’t need any other motor,” Sporza reported Cancellara as saying.

“It’s frustrating that these stories keep popping up about me, but that’s life.”

A video purportedly showing Cancellara making unusual hand movements, perhaps to activate a motor, during his two wins, was published on Youtube.com that spread like wildfire across the internet, drawing the attention of the main-stream media to the story.
