Hold tight and pedal (6)
I believe the answer is:
clutch
I believe this clue is a double definition.
'hold tight' is the first definition.
(I've seen this before)
'pedal' is the second definition.
(clutch is a kind of pedal)
'and' acts as a link.
(Other definitions for clutch that I've seen before include "Brood of chicks" , "Grip tightly for car engine part" , "Keep hold of" , "number of eggs" , "Tightly grasp, eggs" .)
