Hi @mariapavs !
While it is true that you want some clearance between you and the bike for safety, not too much is needed on a road or hybrid bike like this one. You should likely have little trouble mounting or dismounting the bike.
Sometimes with mountain bikes, we recommend more clearance, as dismounting can happen more unexpectedly during that activity.
As @REI-JimL mentioned, there are some other step-thru options that we could explore. I’m just not sure if they might be more relaxed than what you are looking for. Here is an example of what we are talking about. I own this bike personally in addition to my road bike and I love it.
With all that being said, I do think you will find the large CTY to be a better fit than the medium of that is the direction you go in.
Hope this continues to be helpful dialogue!
