Wheel bearings are generally sealed and so last well. Brakes tend to be easier to access and so don’t last - but it doesn’t matter because they typically wear enough before salt/dirt gets them that they will be replaced as part of normal maintenance.
An electric motor is sealed too. The point is that these components aren’t anything new and individually won’t introduce and new types of unexpected failures.
