What bike to choose?

Australian here. I really like this cult, im 5ft10. I want to do more street and some park. Not sure if I should go 2.05, 2.75 or 21.0.

I like this cult. It has no free coaster tho. Should I get just buy one down the line?

Alternatively. There is a cheap fitbike that comes with one but is a smaller 2.05 frame.

And the Sunday. I really like. But the cheaper and better colour is gone. So I’d be paying $1600AUD over the $1400.

New to bmx. Done a bit of skating. I wanna do mostly street, and maybe a tad of park rarely
