ixion

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

'he was bound to wheel' is the definition.
The definition suggests a singular noun which matches the answer.

'one by ten noon' is the wordplay.
'one' becomes 'ix' (I can't explain this - if you can you should give a lot more credence to this answer).
'by' says to put letters next to each other.
'ten' becomes 'IO' (IO resembles i0).
'noon' becomes 'n'.
'ix'+'io'+'n'='IXION'

Can you help me to learn more?
