I've ridden in and through the region several times, and would certainly recommend the cycling there. There are obviously lots of fantastic mountain roads, and some lakes not too far away. The roads tend to be decent quality (better than many other parts of Italy) and in many of the larger valleys there are separated bike paths that give a nice alternative to the main roads, which is something that doesn't exist in most of the rest of the country.
German appeared to be by far the dominant language in many parts of the region, and I had very little Italian.
