Watch a mum knock her son off his bike after warning him to avoid 'idiots'

The hilarious moment a mother knocked her son off his motorcycle minutes after warning him to 'watch out for idiots' has been captured on a rider's helmet camera.

The video begins with the mother and son duo having a conversation about conjunctivitis. After about a minute of chatting about people with gooey eyes, the son walks away to get on his motorbike.
