I’ve heard people have trouble with HR while biking but my experience is pretty good. And I ride a bit of everything. As of connection issues, I don’t think that would be a problem, I don’t see the reason. Battery and hot sun could be a problem sometimes, but that depends on weather and duration of the activity. I’m still waiting for full sunny day this spring 😬
So yeah, dedicated bike computer is most certainly a better option, but I still think I would use this mobile/suunto watch combo. I guess that would be good enough for most average users. Apple as it seems thinks this too, so it’s probably not entirely nonsense.
