To get together, cycle home first (2,6)
I believe the answer is:
in tandem
'to get together' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'cycle home first' is the wordplay.
'cycle' becomes 'tandem' (tandem is a kind of cycle**).
'home' becomes 'in' ('he's home' can mean 'he's in').
'first' says to put letters next to each other.
'tandem' put after 'in' is 'IN TANDEM'.
Can you help me to learn more?
(Other definitions for in tandem that I've seen before include "Together - as on a bicycle made for two" , "Working together" , "'One behind the other, as on a bicycle (2,6)'" , "Manned it as twosome" , "One behind the other or alongside" .)
