I’m recovering from a back injury, and the reason I want to upgrade the bike is because I’m using it much more than before, and cycling is more recommended than running with back issues (generally speaking). So I’m currently intending ~ 1 hour rides a few times a week in a bike path. But to reach there I have a short commute with more city bumps.
