Everything on my S1 WAS TIP TOP until one day I went to turn it on and a second after the green light came on it shut off and I havent got it going since. I had only had it three months and thought the warranty would cover it but I wasn't going to pay to have it shipped out to them over buying a GOTWAY and forgetting about the problem.
I'm moving to Miami on the 1st, flying out, getting rid of everything. Busted ninebot has to go.
You could part it out and come up ahead with the charger and batteries alone.
I also have my GOTWAY mcm4 which runs like a dream that I have to do something with because it can't fly out with me so any reasonable off I will consider.
Make me an offer.
