Novice politician cycling backwards (4)
I believe the answer is:
tyro
'novice' is the definition.
(term for a beginner)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for tyro that I've seen before include "New" , "'Beginner, novice (4)'" , "Initiate" , "Spell for rookie" , "Novice; Tory (anag.)" .)
