The possibility to track the distance for a ride with the speed sensor 2 without manually starting an activity is great but it would be nice if a minimum distance threshold could be set by the user before a ride is uploaded as an activity. Otherwise, just rolling the bike outside of the basement is added as a 50 metre distance activity...
On a side note, it would be very convenient if gear and activity type (fitness, training, etc.) could be added in dependance of a sensor, e.g. a commuter bike is automatically added for all activities recorded with a certain speed sensor and the activity is labeled as fitness.
