Hi all,
I had a 30H error on my e-bike (Himo c26). The display showed a 30H error, I could not turn on the light, although the display showed that it was on. Also, the electric motor did not work. The battery was 100% full. I disconnected all the cables except for the display and the battery. It was still showing error 30H. I tested with components from another same Himo c26 bike and came to the conclusion that the cable / electronics for brake detection is faulty. The display and speed lever as well as the front and rear brake cables are connected to this cable. Only when I released both brake levers (they were not attached to the brake levers) did the 30H error disappear and the light started working normally.
