sorry if I write you in english, but unfortunately I don't speak german.
I've been already surfing your forum and searching for information for my Jetstream P8 f, but only now I decided to introduce myself.
I'm a daily commuter (10 to 30 km per day), I live in Turin and I'm one of the staff members of your italian "twin" forum bicipieghevoli.net.
Even if the use of bikes in italian cities is not so common as in your country, they are getting more popular and we also have new member registering every day. Of course you're all invited to take a look to it or refer to me for any request.
Using google translate it's not too hard to read it (better to translate to english) it just takes longer time.
As soon as possible I will show my bike and accessories in the dedicated area.
