No, you can't lock the E2 Pro electric scooter without a phone. Locking, like anti-theft mode or activation, requires a connection to the Segway-Ninebot app via Bluetooth on a smartphone. If the app causes problems, reinstall it on another phone to unlock.
1. locking without an app: It is not possible to lock the e-scooter directly without an app. The safety functions, such as the Air Lock, require the use of the app to enter a code that is requested when the scooter is started.
2. changing the riding mode without the app: The riding mode cannot be changed without the app. The app is required to change settings such as the riding mode (Eco, Standard, Sport, Walk).
E-scooters are generally not completely waterproof, but do have a certain degree of water resistance. For example, you should be able to ride your scooter in the rain without any problems.
The scooter does not have cruise control. Information about such a function is not included in the available data. If you have any further questions, please let me know
