I have a half dozen bikes but most ride a Specialized Tricross Comp (gravel/ADV) and Brompton. I may be downsizing from a home to condo soon and will probably get rid of everything but the Brompton. As it is, I split exercise rides pretty evenly between the Tricross and Brompton, but the Brompton is my go to for the city, utility, travel (car), and bicycle touring (I don't commute any more). I've tuned the Brompton to be nearly as comfortable and efficient as the Tricross so the versatility of the fold makes it an easy decision for me.
