I don't know how to drive a motorcycle, = same thing
No, because in English you don't use "drive" for motorcycles. You have to use "ride" even if you are the one operating the motorcycle.
Good to know, thanks!
I see! Thanks!
You have a word missing. I do not KNOW how to ride...
It is not needed, because the "knowing" is implied in the he verb "umět" itself.
The correct word "know" was missing from the options
