Bikes are a lot less delicate than people seem to think. My daily driver has road bike rims and tires. They're quite durable. The region has some bike paths that are crushed limestone on hard clay, and sometimes I find myself on gravel roads, off-road shortcuts, or even "easy" mountain bike trails. The main issue is comfort. Riding rough roads on hard tires gets old after a while. Also, real MTB'ing, where the trails are designed to be challenging, is its own beast. I also prefer avoiding car traffic if possible.
