Some quicker bikes feature by pavement? (4)
I believe the answer is:
kerb
'pavement?' is the definition.
(thesaurus)
'some quicker bikes feature' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'KERB' is hidden in the letters of 'quicker bikes feature'.
'by' is the link.
(Other definitions for kerb that I've seen before include "stone by the way" , "Pancakes" , "Edge of road" , "Pavement edging" , "Stone edging to footpath" .)
