Yes! You are able to pause your rental as many times as you'd like, as long as it doesn't exceed the maximal rental duration. Just use the in-app Pause function. The scooter will not be able to be moved, but you will still pay the price per minute.
After 2 hours paused, the rental will automatically end. Once you're back, simply end the pause mode in your App to unlock the scooter and continue riding.
