Recover to ride again (7)
I believe the answer is:
recycle
I believe this is a double definition.
'recover' is the first definition.
(thesaurus)
'ride again' is the second definition.
('cycle' is an answer for 'ride' so perhaps 'recycle' is OK for 'ride again')
'to' acts as a link.
(Other definitions for recycle that I've seen before include "What Greens do" , "Process something so it can be used again" , "Process for further use" , "salvage for further use" , "Convert waste into form to be used again" .)
