The most unhelpful, angry Bavarian I've ever met. I stopped by and asked if they could service my…read morebike that I bought on ebay. The guy threw a fit, and said "Wir machen das nit, nein, nein, nein! Das wir machen nit!" and insisted that they only do maintenance on bike that they had sold.
For a more relaxed, friendly service, go to Glockenbike up the street.
