Looking for potential riding buddies in Luxembourg (or failing that, routes)

I’m moving to Luxembourg for a new job before the end of the year and going from familiar leafy Surrey to the middle of Europe. It looks like good for riding both on and off road but I’m aware that finding the best routes in either discipline are easier (and more fun) with local help.

Does anyone know where I can start. Don’t mind speaking French of course, just I don’t speak Luxembourgish (who outside the country does?).
