But to save batterytime the tracker have ''sleeping'' cycles until it is ''waiting for movement'' again.

- If someone is moving your bike, you can get a notification in the app (Read how to get notficiation here).

- This movement sensor is measuring all movements on the bike. Just remember, if the bike is put in a place with strong winds, or in a bike rack where people are putting their bikes, you might get some false alarms due to these movements.
