In the case of the bicycle example, what is learned consciously is of a
different nature from that learned unconsciously.  Your conscious
learning about bikes is largely in the form of acquiring formal rules:
"to turn left lean the bike to the left and turn the handlebars left".
Your unconscious knowledge is more in the form of recognition of
patterns, perhaps quite complex patterns, and reaction to them.  Your
unconscious has detected an association between turning the handlebars
right, and turning a corner to the left.  But it is not a formal rule.
The unconscious learning does not have the type of formal structure you
tend to associate with knowledge.  It is more a cumulative effect of
experience.

I've taken the liberty to add the word "not" above.  I'm guessing that
was what you were intending to say.  To a large extent I agree.  I
believe unconscious learning is vitally important, and a major function
of consciousness is to expedite unconscious learning.  This might seem
to contradict my comments on formal structure and conscious learning.
But the formal structures of conscious knowledge are usually encoded
linguistically, and the unconscious can learn to recognize the patterns
of associated words without regard to whether they represent a formal
structure or not.

I would say that conscious learning is less accurate than unconscious
learning.  Perhaps this is because it is rapid, so based on less
experience.  As for rapidity of conscious learning, this is due to
consciousness providing a feedback system which reinforces learning.
That is, since we are aware of our conscious thoughts, they are in
effect recycled as input, and this constitutes a reinforcing feedback.

An excellent question.  However I think this has it backwards.  That
is, unconscious learning is already quite broad.  Consciousness
provides a focus, so provides narrower learning.  By way of example,
conscious rote memorization is very narrow.  The unconscious learning
associated with the bicycle example requires very broad learning, since
a non-obvious association was learned.
