The association used to have different names in the different Swiss languages. At that time, it was called IG Velo in the German part. A year or two ago, they standardized it to be called "Pro Velo" throughout the whole country. Chris gave the link to the brief info available in English, their main page is only available in
German or
French. There are local branches of the association
all over the country, here is the
one in Baden that was probably organizing that.
