Hello I am a New user and have had my Niu for a few weeks and it has worked perfectly untill yesterday… I was out riding when it just died, the display went black. Had about 70% of battery left.
Tried tog disconect the battery and then reconect without sucess, the display ass still black and nothing happend when turning the key. Had to walk with it home. After loading for 2 minutes I tried again and it works as it should……
Anyone that knows what it could be or have has a similar problem?
