I have the previous phone, 7 or 8 years old, still running as a GPS or Strava on the bicycle. That phone is electronic waste otherwise, on the motorcycle I can connect it to the charger and the battery is not a problem. In this context "don't mount any phone ..." is wrong. If you want to say "don't mount your main phone", you are right, I never do. Only when I cycle I use Strava on the main phone in the pocket, not on the handlebars, but this is not the use case in the article.
