My city bike / all rounder is my upgraded '66 Moulten... the ride to the south co-op (where I teach classes) is only 8km while the commute to my shop is 32 steps. The north shop (co-op) is only a few minutes away from me and is not even a warm up.
I also ride a 2001 bikeE CT which is a great city bike... and quite nice for rambling through the river valley.
These have been my go to bikes for the season, sometimes they get a break when I decide I want to change it up and yesterday used my 1954 Raleigh Sports.
