Hello , I am reaching out to ya'll for your advise. I still can't get my new ebike to zoom zoom. Nothing at the motor, internal controller so it's a bugger to test it's all in the hub. Error code 10 so communication is not letting the power to hub motor either. Battery @ 52.7 volts , so it's perfect. I'm perplexed . Must be a sensor, communications circuit , or controller circuit ? There's probably 3 in there , don't really feel like disassembling and voiding warranties but this sucks I am ready to ride this thing
