Cockeyed Bob leaving on bike (5)
I believe the answer is:
cycle
'bike' is the definition.
(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for cycle that I've seen before include "Recurring pattern of events" , "Travel (on wheels)" , "schedule?" , "Repeating sequence" , "Aeon" .)
