Henry Ford initially displays seat and cycle parts (4-5)

I believe the answer is:

half-moons

I'm a little stuck... Click here to teach me more about this clue!

'parts' is the definition.
(half-moon is a kind of part)

'henry ford initially displays' is the wordplay.
'henry' becomes 'hal' (short for Henry).
'initially' says to take the initial letters.
'displays' becomes 'moons' (mooning is a kind of displaying).
The first letter of 'ford' is 'f'.
'hal'+'f'+'moons'='HALF-MOONS'

'seat and cycle' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?
