I found these sentences from a passage "Ann rides her bicycle. Ann rides her little bicycle to work. Ann rides her little, red bicycle to work every day"
I don't think those adjectives are coordinate so they should not be separated by a comma.
I wonder why we need to put a , (comma) between these adjectives (little and red)?
Thank you!

Commas are used between adjective words or phrases when the adjective independently has certain properties: for instance it is not primarily attributed with one, and then with less importance for the other attributes.
The commas are not necessary where the meaning is obvious.
Compare:
Since "red bicycle" is not understood as a special type of bicycle, the comma doesn't help to clarify anything. We know without the comma that "little red bicycle" means "bicycle which is little and which is red".
"red [something]" could be a special kind of something. For instance "red book" could have a meaning other than simply a book whose cover happens to be red. Because it is not the official name of the book, and the nickname is only used by a small group of people, it is not capitalized as Red Book. (See Dragon Book for instance).
In the second example, we can drop the comma, because the old man is probably not reading stories from some special "red book of stories" that isn't actually red colored. If it were the title of the book, it would be capitalized Red Book, and then the comma would be entirely inappropriate.
In the first example, we may not add a comma.
How about with more than two adjectives. Continuing with the "red book":
The presence or absence of a comma does not resolve everything. For instance:
If we add the comma, we clarify that the second interpretation is intended. If we omit the comma, it remains ambiguous.
In speech, we can say "deep blue" as one word, and leave a pause afterward, but in writing "deep-blue" or "deepblue" would be considered erroneous.
This is one of those situations in which the written language must be restructured to avoid ambiguity, where spoken language doesn't have to.
That brings us to compound adjectives. You can see how the commas are visually helpful in breaking up the clusters of words into chunks:
Commas are practically mandatory in situations like this; it looks quite bad when written without commas, and far worse with misplaced or inconsistent ones:
In the first example, the writer confused the reader because he or she started using commas to separate the nouns, creating the expectation that commas are being used consistently and correctly, but then neglected to do so between "cornered" and "public".
Inconsistency and incorrectness with regard to the placement of commas can often be worse than neglect to use commas at all.
