This gives me all the cycling data I need, but also gives me step counts, all day HR monitoring, sleep, steps, calories, etc. This helps save the battery on the phone too so I don't have it being drained by a GPS app so I can actually make a call if I need to after a long ride.
+1 for the Garmin VivoActive HR. Two pushes of a button and it works for either my rides or my runs. I've owned several Garmin products and this is by far the easiest interface I've ever had for a GPS watch. Unlike jitteringjr, I just wear it on my wrist even on the bike. I can look at it if I really want to to see my average speed, distance etc., but find I prefer not having the numbers staring up at me from the handlebars all the time....particularly when suffering against a strong headwind
