In your other thread, you wrote that you wanted the bike for
casual riding in the city and sometimes parks(I don't actually need one for rough surfaces)
but you are posting pics of mtbs with knobblies and big tyres ... no, go for one of the hybrid or trekking types recommended by
@AndyRM.
You are only making work and discomfort for yourself if you ride MTBs like that in the city and round parks. (Well, you'd be making even more work for yourself and probably the A&E department too, if you rode them on serious MTB terrain but ...)
Seriously, I ride my 20" wheel folder with its 'city' tyres for miles along much rougher paths than you get in parks (ie along my local canal towpath which gets seriously muddy in wet weather, rough and furrowed in dry weather and grassy all year round, apart from shortish improved stretches which are hard and stony or finely-crushed stone and eminently-skiddable/slippable, or even shorter ones which are tarmac or flagged.
Now, I am an old lady and I am not suggesting that you buy a 20" wheel folder - but the best choice for you and the riding you want to do will definitely
not be either a 20" wheel folder and nor will it be an MTB-SO!
