Post Body

I just purchased a Aniioki A9 Pro Max Dual Motor. I got about 40 miles out of it before the bike started showing error 21 on the screen and no power is shown going to the front motor. I’ve disconnected and reconnected each wire connection, uninstalled and reinstalled the battery several times, and factory reset the bike. I still have full power to the back motor but can’t get the front to work again. Has anyone had this problem or can offer any advice on fixing the issue before I bring it to my local bike shop? Thanks!
