I have been to many bicycle stores in Munich and this has by far been the best experience I have had in purchasing a bike.
The guys at the bike store were very knowledgeable and gave me a lot of valuable inputs (from various points of view) to help me narrow down the kind of bike that I thought was the best fit for me. They even let me try several different types of bikes (road, hybrid/fitness, city, etc) just so I could get a feel for them before I made up mind about the bike I was interested in.
The quality of the bikes they had was excellent and they had an expert mechanic on-site who went through the entire bike, and ensured that all the components of the bike were just as they should be before they handed over the bike to me. They even offered me a free first bike service/maintenance appointment.
The staff spoke both German and English, and were very friendly and tried to assist me in every way possible. 10/10 highly recommended!
