I would love to have the ability for the app to select gear dependent on location. I have one bike in Holland and another in the UK and it would be great if it automatically knew which bike was used where rather than me have to manually change it every time.
I would like gear use preferences based on activity type. My default bike for "cycling" is my mountain bike, my only bike. When I do "indoor cycling" at the gym it also chooses this by default. There should be a more granular way to choose default gear.
