[Grammar] Ride bicycles/a bicycle

[Snappy]

If I say, "I can read a French novel," it means that I can read a single French novel (not more than one).

Then, are the following sentences acceptable?

I can ride a bicycle.
I can ride bicycles.
Can she drive a car?
Can she drive cars?

No, it means any that comes in your way.

Of course, I cannot ride more than one bicycle at a time.

The point of my question is:

"I can ride a bicycle." (Is this gramatically okay? Doesn't it imply that I can ride only a particular type of bicycle?)

I can ride bicycles. (Do native speakers of English misunderstand that I am an acrobat?)

I can ride a bicycle.
In this sentence 'a' gives the noun a general meaning (=any representative of the class). The sentence states your ability to ride a bicycle. It does not imply any particular type of bicycles.

Thank you for your comment.

Can I use "I can ride bicycles" as well. If yes, what's the difference in nuance between "I can ride bicycles" and "I can ride bicycles"?

I can ride a bicycle. - is about your ability to operate this type of machine.

I can ride bicycles. - is basically about the same. There may be some stylistic or application nuances that differ it from the first pattern but you'd better ask a native speaker about it.
