Ring about daughter getting a bicycle part (5)
I believe the answer is:
pedal
'a bicycle part' is the definition.
('pedal' is part of 'bicycle')
'ring about daughter' is the wordplay.
'ring' becomes 'peal' (synonyms).
'about' means one lot of letters goes inside another.
'daughter' becomes 'd' (genealogical abbreviation).
'peal' going around 'd' is 'PEDAL'.
'getting' acts as a link.
(Other definitions for pedal that I've seen before include "Foot-operated lever" , "cause a revolution in cycling?" , "Plead for bike pusher" , "work with press from Oxford?" , "One may be sustaining" .)
