Exercise wheel locale (4)
I believe the answer is:
cage
'exercise wheel locale' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cage that I've seen before include "In which birds or animals are kept" , "Wired enclosure" , "Enclosure made from metal bars" , "Nicolas - - (films)" , "Place of confinement" .)
