Girl on cycle visits boy in trouble (6)
I believe the answer is:
hassle
'trouble' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hassle that I've seen before include "Bug" , "Informally annoy or bother" , "Harass; pester" , "Les has (anag) - a great deal of trouble" , "Annoy continually" .)
