I will suggest that the language in this forum will be strictly in English.
I think that the topic in other langue’s beside English is a petty because the discussions is not understood by all members!
Ibikes are sold to many other foreign counties as wall as here in the States.
Whenever I come across a question in other language and someone is able to answer to that question in this forum, I find the beauty of it in that we are helping each other.
Once I helped a foreign friend, who cannot speak English, in setting iBike up. He thanked me, saying that a problem of 6 month struggle is solved in a snap.
As John said, I could understand what is going on in that thread of the question with the help of Google translation. Questions in other languages are very few. So, just let it be like that!
