Breakfast radio host Eoin Cameron has copped a tongue lashing from Perth cyclists over a flippant remark he made on air last Friday morning.

The popular ABC presenter was discussing repairs to the Fremantle rail bridge when the conversation briefly turned to cyclists.

Eoin Cameron is under fire for a brain snap on air involving cyclists.

"I'm going to get a roo bar on my car to sort out the cyclists, they're proving to be a bit like mozzies in my area," he said.
