Meant to travel with daughter's bike (6)
I believe the answer is:
tandem
'bike' is the definition.
(I've seen this in another clue)
'meant to travel with daughter's' is the wordplay.
'to travel with' indicates an anagram (I've seen 'travelling' mean this).
'daughter' becomes 'd' (genealogical abbreviation).
'meant' anagrammed with 'd' can make 'TANDEM'.
(Other definitions for tandem that I've seen before include "Two-seat bicycle" , "Bicycle for two (plus)" , "Two-person bike" , "Two wheels for two" , "Two-wheeler for two" .)
