My reasons for preferring EUCs:

- It can be easily combined with public transit. Its much smaller footprint causes less trouble for you and those around you. You can place it behind your legs while sitting and keep between legs while staying.

- Absolutely no issues with stairs and escalators (at least with the models on the lighter side).

- You can get it with yourself into office. In many places you can not bring your bicycle or scooter into a desk space or it will be strongly frowned upon.

- It does not take much space when stored at home.

- Because of the smaller footprint and lack of protruding parts like handlebars, it's much safer and easier to move in a relatively dense pedestrian traffic.

- It easily fits into a car's trunk.
