Go by bike in section of icy clearing (5)
I believe the answer is:
cycle
'go by bike' is the definition.
(I've seen this in another clue)
'section of icy clearing' is the wordplay.
'section of' indicates the answer is hidden within the clue.
'CYCLE' can be found hidden inside 'icy clearing'.
'in' is the link.
(Other definitions for cycle that I've seen before include "Go by bike" , "Wagnerian series?" , "Recurring series of changes" , "Regularly repeated sequence (of events)" , "Repeated round of events" .)
