I want to buy a bicycle

What a nice weather outside, isnt’t it? I do not know about you, but I’m so drawn to nature, somewhere. River, forest.
For this I want to buy some good beach cruiser.
The question is which one is better?
First of all, I am interested in reliability and convenience.
What else should I pay attention to? Obviously the frame should be for women. Has to be suited for height? Or is it not necessary?
I just understand that I want a blue color 🙂 And we’ll deal with everything else.
