I’m piling on with others pointing out that your seat seems too low. I also am surprised that you’re having knee pain but seeing the photos of you riding explains that.
If you like bicycling, I’d also suggest looking into getting a better bike. Yours looks heavy, which might also explain your pain and discomfirt.
I think someone else also made this point, but I’ve personally noticed that too low of a gear can be less comfortable/efficient as well. Professional cyclists maintain extremely high rotational speeds but I don’t think that’s sensible for anyone else generally. (And some pros use higher gears and slower pedaling too anyways.)
