Can anyone provide advice. I'm on my second Kalkoff pedelec, it's a Endeavour purchased at no small expense two years ago. I've already had the motor changed once; there was an intermittent fault with the torque sensor & apparently its easier to change the whole system. I use the bike extensively on winter touring holidays in Spain. Just finished a long ride and again the bike appears to developed the same fault? No matter how hard i press the pedals or adjust the power settings I get no motor support, then all of a sudden I get burst of power that quickly fades away. The bike is serviced by the Kalkoff dealer in the U.K. Before I start another rant with the dealer has anyone had similar problems & more importantly found an answer?
