回过头
I am reading a Chinese practice book and I am stuck on the specifics of this sentence:

*After the main character is called by a friend*
他回过头一看，有个男的骑自行车过来．

I understand that it means something along the lines of: He turned around to give a look, it is a man on a bike coming over.

But what is the direct translation of 回过头？ As far as I know, 回=return，过=go over, and 头=head. What are the specifics?

Answer

It's same with“He turned around" “过来”is just for emphasizing the action More important, it's just an idiomatic expression of Chinese,and you also can say“回头一看”.

Answer

Here, to help you understand, "过" can be silenced, which makes the sentence to "他回头一看，有个男的骑自行车过来． 
" As "过" added, it can be understood as a result that he has turned his head back.
