Dash through cycle lanes (4)
I believe the answer is:
elan
'dash' is the definition.
(I know that dash can be written as elan)
'through cycle lanes' is the wordplay.
'through' indicates a hidden word.
'ELAN' is hidden within 'cycle lanes'.
(Other definitions for elan that I've seen before include "Energy, style and enthusiasm" , "Vigour, panache" , "Dash in Paris" , "Panache - ardour" , "Vigour, style, enthusiasm" .)
