Couple cycled a little bit (4)
I believe the answer is:
mite
'little bit' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for mite that I've seen before include "Minute creature" , "Old piece" , "The widow's small donation" , "Tiny creature found in food" , "Very small creature or child" .)
