Are the police allowed to give you a breath tested if you are drunk on a bicycle? And could he get points on his license?

My mate was riding home on his bike (standard, not electric), got stopped by the police who gave him a breath test and promptly arrested him. I fully understanding him getting booked for public intoxication or even endangering the public. But why the breath test and the cops said he could get points added to his license?
