Sofia,
I bought a Clem frame and have been riding it for a couple months, it’s one of the best utility bikes I’ve owned.
I have 60mm tires on it now and it will easily fit 70s.
I lucked into being on the waiting list for a Platypus and recently built it up.
It easily fits 55mm tires.
I’ve grappled with the the same question.
I thought I would give the Clem to my niece but she doesn’t think a nice bike is justifiable.(crazy, right).
So my Clem will be a more heavy duty utility bike to carry a load and have big fat tires and the Platypus will be a more elegant lighter build.
So if you’re looking for a little nudge from the devil on your shoulder….doooo it😈
