These ridden miles — newspaper articles follow (6)
I believe the answer is:
mopeds
'these ridden' is the definition.
(mopeds can be ridden)
'miles newspaper articles follow' is the wordplay.
'miles' becomes 'm' (abbreviation).
'newspaper articles' becomes 'opeds' (op-ed is a type of newspaper article).
'follow' means one lot of letters go next to another.
'm'+'opeds'='MOPEDS'
(Other definitions for mopeds that I've seen before include "Low-powered motorbike" , "Low-powered motorbikes" , "Light motor cycles" , "Lightweight motorcycles" , "Low-powered motor-cycles" .)
