I had decided on the Kettler exercise bike because I fell with a no name product ever on the nose. When the unit arrived, I unpacked it and set up. The good quality of the product has pleasantly surprised me. Had it not as good expected. After a construction of about 30 minutes, the first sample seat. CLASS. Simply SUUUPER. The exercise bike is absolutely quiet, comfortable and very well made. Real stable. The computer is amazing. Many settings for each workout.
