From what site did you buy your Kugoo S1 ? Geekbuying or Geekmaxi or somewhere else ?
What is your inscription in the motorweel ? Starting with WB something ?
I think I have read about similar problems on the earlier Ryssian Kugoos.
Their is a hall sensor inside the break that controls the electrical brake. Might be that issue that Hall IC is damaged in some way. Their are guidelines in the Ryssian forum how to fix this.
Not very easy but probably not too difficult either. Think you can find videos on youtube to how to take the brake apart and put it back again.
Probably the biggest problem is to get a new hall IC. Can probably buy it from some Ryssian webshop or Alibaba.
Though a bit strange regarding the light.
Blinking back light should only mean you have activited the light on the front as well.
Then when breaking with lights on it will be a steady red back light insteed.
So might be something else then the Hall IC.
Though the indication that brake is on at the display when you turn on the scooter indicates that something is wrong with the Hall IC if I remember the Ryssians correctly.
I know people have discussed similar tings in the Ryssian forum but I didn´t spend to much time on it until I know I have someting to fix on my bike and need to dig into it.
