chedech is a good price ($2k) at the lower end but carbon a worry for rough and tumble of public and car transport.
ti brommie all in is not cheap ($3-4k) and a hassle to pull together. Ultimately genuine Brommies are fine and if I really needed the bike in the interim, that is what i would have gone for.

And they are fairly lightweight and can be easily built into ~16lbs hybrid bike or ~18lbs light mountain bike.
I like both but not for commuting due to folded size and fold/unfold faf.

There is no other bike I am aware of which promises to cover its range. We will indeed see if practice lives up to theory.
