How do publicans manage those on their bike?
I believe the answer is:
handlebars
'those on their bike?' is the definition.
I can't tell whether this defines the answer.
'how do publicans manage' is the wordplay.
I cannot really understand how this works, but
'manage' could be 'handle' (synonyms) and 'handle' is located in the answer.
The remaining letters 'bars' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for handlebars that I've seen is " Part of bike".)
