Charged the electric bike battery because I was staying there for some hours. Started on the way home and after some heavy hills (about 3 km)it was completely dead. The electric bike kit system was running like normal up to this, but suddenly all power on the electric bike motor wheel was gone.  <\/p>\n<p>Those three led lights on twist throttle for electric bike battery were still lit. I tried to turn e-bike off and on again, but same result.  Today the electric bike kit is still dead.  <\/p>\n<p>Do you have any idea? Measured 0,1 Ohm between the electric bike motor(hub motor phase wire: yellow, green, blue).Infinity between hub motor cable and hub motor cover. So it does not look like it is burned. The electric bike motor controller has 41,8 Volt input.  <\/p>\n<p>Measure the hub motor hall sensor:<br \/>\nRed, black, yellow, blue, green wires.<br \/>\n1.The voltage between red and black is 4.5V;<br \/>\n2.The voltage between yellow and black is 4.2V or 0V,(When use hand to turn hub motor, the voltage will change from 0~4.5V~0~4.5V)<br \/>\n3.The voltage between blue and black is 0.2V; (When use hand to turn hub motor, the voltage could not change)<br \/>\n4.The voltage between green and black is 0.1V. (When use hand to turn hub motor, the voltage could not change)<\/p>\n<p>From above test data, I doubt there were two hall sensor inside the electric bike motor that were broken.<\/p>\n<p>Electric bike hub motor kit was gone, how to solve it?<\/p>\n<p>Hub motor, electric bike motor, electric bike kit supplier: Leaf Motor Technology Co., Ltd<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Electric bike hub motor kit was gone, how to solve it?
