I was riding for a shorter distance steep uphill in level 5 and suddenly the <a href=\"https:\/\/www.leafbike.com\/products\/e-bike-hub-motor\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>bike motor<\/strong><\/a> was making an obscure humming sound and was vibrating very strong. So I stopped immediately and shut down the system. I checked the hub motor and the cable for overheating but they where just with normal temperature. After a while, I already turned to go back downhill, I started the system again but the problem still exists. It seems that it is maybe a problem with the controller because now there is no reaction in changing the power level (1-5) or turning the throttle on. The hub motor gets only around 10 Amps with a max. of 590W (measured with a installed Amp\/Volt meter in between). When starting pedaling or with the throttle with low speed the vibrations are immense but when I gain more speed the vibrations are reducing to a lower level but they are still there. When staying still and pull the throttle full, so the tire normally can spin free, only the vibrations and a loud humming sound exists. I know I do not have any warranty more leftover on this system but maybe you have an idea how I can repair this for a budget price.<\/p>\n<p>I already solved the bike conversion kit system problem.<br \/>\nFunny what unexpected small things could cause some different technical reactions. The problem of the bike conversion kit problem above was, that one of the 3 phase cables to the motor was broken. By the effect of the depicted problems above I really thought that something in the controller was burnt-out but happily I could find the broken cable very soon so now everything<br \/>\nworks fine again.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today I hit in a technical problem with the 20inch 48V 1000W bike conversion kit (Item ID:#LBCK20481000FN).
