Select a moped in the emmy App and click on "Reserve now" (free for 15 minutes) in the detailed view. When you reach the moped, click on "Start Rental" to open the helmet box of your moped. The helmet box will then make a typical clicking sound and the moped is ready for you to ride.
The helmet box isn’t opening or you cannot start the moped? Alternatively enter a keyword for your problem at the top of the search function.
