Would these be for wearing while cycling, or as a gear bag during transportation?

For times when I put my bike in my car for rides where I'm driving to the start (after-work rides, most often), I have found that one of my daughter's softball backpacks is excellent for packing the gear I need because of the following features:
- Main compartment has a removable separation panel, dividing it into upper and lower sections. The upper section I use for clothing. The lower section is accessible with its own mesh-panel zippered flap, which makes it great for shoes.
- Exterior pockets (intended for bats) make a great place for water bottles.
- Front smaller pocket for computer, lights, etc.
- Helmet-holder (tucks away in a zippered pocket when not in use)

The one I use is similar to this...
