a. If the battery is powered, please use a battery voltmeter or a multimeter to test the battery voltage. The voltage of a full battery is 54.6.
b. If the battery cannot be charged or the battery power cannot be displayed, it is a battery problem and needs to be replaced. If it is determined to be a battery problem, you do not need to check the following steps.

1. Press the power button to start the bike.
2. Press + and - for 3 seconds at the same time to enter the parameter setting. Press M to set parameters to P08 and + to set numbers to 80-100. Press + and - to save.
Set PAS1 to 5 to achieve the release speed.
Please charge the battery more than 10+. Press the power button to start, press the M key to POW, we need to check the battery voltage. The voltage of a fully charged battery is shown at 54.6V. Please send me a photo of the display for confirmation.
