Hello from Geneva, Switerland. Last week, my neighbor asked for help with her Fuell 1S she bought last year and drives 15-20km everyday. Since a couple of weeks, the motor makes a noise which gets louder day after day. As no local reseller nor bike repair shop seems to be excited about opening the motor, we decided to made a short video and ask for help on this forum. Any way that can help solving this problem is welcome!
