I have a BMC hub motor in the front wheel of a cruiser bike. The wheel will start and run as long as there is power applied by the throttle. However, after coasting, the motor will not respond again until it comes to a complete stop and rests for a few minutes. To isolate the issue, I changed the battery and used an old pack with no BMS. The same symptoms exist so I eliminated the BMS shutting the pack off. The problem exists with or without the CycleAnalyst connected, I have set the CycleAnalyst speed to 99 to eliminate that cut out possibility. I also raised the Amps cut off to 30 Amps so the CycleAnalyst can't be the problem. I also swapped out the throttle with a brand new throttle and the same problem exists. Lastly I swapped out the Crystalyte 20A controller with an Infineon 25A controller and same problem. The motor runs until I let it coast with no power, then it won't re-start. Since I have been able to re-create the problem with 2 different batteries, two different controllers and two different throttles, I have to conclude the motor is the source of my pain. What could it be? Weak hall sensor signal? Incompatible controllers? Ghost in the machine?
Any help is appreciated.
