I am hoping someone can answer this question as there isn't anything on the Kalkhoff site. I have purchased a Kalkhoff Image 5.I Advance with the Impulse Evo motor. Its great but I have found a bit of a "glitch" - maybe I am missing something. In the settings there is a shift sensor change - which I wasn't sure what this does. As normal I started to fettle with the settings and I put this onto the fastest setting of 50ms. Unfortunately, when I do that the crank sensor seems to not engage until after the first pedal turn - tricky at roundabouts or traffic lights on a hill! I returned it back to 150ms and it seems to be ok. I am just wondering if someone else has had this problem?
