Outlaw speed bumps on bendy road (9)
I believe the answer is:
desperado
'outlaw' is the definition.
(desperado is a kind of outlaw)
'speed bumps on bendy road' is the wordplay.
'bumps' is an anagram indicator.
'on' means one lot of letters go next to another.
'bendy' indicates an anagram (the word is bent out of shape).
'speed' with letters rearranged gives 'despe'.
'road' anagrammed gives 'rado'.
'despe'+'rado'='DESPERADO'
(Other definitions for desperado that I've seen before include "reckless one" , "Bravo" , "Road speed (anag.)" , "Bandit, outlaw" , "Reckless guy" .)
