Pedal off with one group to find chief guide (4,5)

'pedal off with one group to' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'chief guide' is the wordplay.
I cannot quite understand how this works, but
'chief' could be 'lead' (I've seen this in another clue) and 'lead' is located in the answer.
'guide' could be 'pilot' (pilot can mean a navigator) and 'pilot' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'find' is the link.

Can you help me to learn more?
