Man perhaps bananas to go round bus when cycling (7)
I believe the answer is:
husband
'man' is the definition.
(I've seen this before)
'perhaps bananas to go round bus when cycling' is the wordplay.
'perhaps bananas' becomes 'hand' (hand can mean a group of bananas).
'to go round' indicates putting letters inside.
'when cycling' is an anagram indicator.
'bus' anagrammed gives 'usb'.
'hand' going around 'usb' is 'HUSBAND'.
(Other definitions for husband that I've seen before include "manage wisely" , "manage thriftily" , "Consort" , "Conserve" , "Partner; use carefully" .)
