biciklo en la mateno

Esperanto for bicycle in the morning.

I never knew this!

Esperanto is an international language, a 'help language'.
It is supposed to be a second language that people learn to be able to speak with other people from other countries.
Nobody in the world has only esperanto as mother tongue, though there are children who speak esperanto from their birth on, together with other languages.
So there is no esperanto-country in the world.
To hear esperanto you'll have to go to an esperanto-meeting, there are really many of them, or to listen to a podcast...
For example: http://www.esperan.to/podkasto/epizodaro.html
Esperanto is easy to learn, to write and to speak.
