Pressure to organise deal for bicycle part (5)
I believe the answer is:
pedal
'for bicycle part' is the definition.
('pedal' is part of 'bicycle')
'pressure to organise deal' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'to organise' is an anagram indicator.
'deal' with letters rearranged gives 'edal'.
'p'+'edal'='PEDAL'
(Other definitions for pedal that I've seen before include "cause a revolution in cycling?" , "sustained note" , "Of or relating to the feet" , "Part of cycle" , "work with press from Oxford?" .)
