Blamed Segway/Nine-bot for their shortcomings. Had to go to Segway directly to get a new motherboard, primary battery and 2nd battery replaced. Weeks later the rear brake just broke off. I wasn't even using it. Email below I sent to Segway as well: It is with much distaste that I have to write yet another email with issues with this scooter. I’m starting to wonder at what point do I give up on this thing, ship it back to you guys or E-Wheels, or whoever and ask for ALL of my money back! I’m pretty fed up with the issues, the shotty, worn out front tire with no option for just to purchase another tire (I’m told the entire motor assembly has to be replaced which I will not do. That’s insane), the lengthy time for replacing the motherboard and batteries last time and now this. Yesterday I ran to the grocery store on this scooter and on the way home the rear brake just breaks off. What’s even more crazy is that I wasn’t even using the rear brake at all!!! I was literally cruising down the paved bike trail and it just fell off. I have attached pictures to this email so you can see what I’m talking about. I limped home with no rear break which is a grave safety concern with being able to stop quickly. I feel like the longevity of this scooter isn’t going to hold up and I am now fearful to even use it to commute to work now for fear of it breaking and me crashing and getting hurt. As of now this is my formal email asking to return this scooter and I want all my money back. E-Wheels wasn’t helpful last time as apparently they aren’t an authorized partner of yours anymore and quite frankly I don’t care. That isn’t my problem and they literally blasted nine-bot (See attached email) about issues from their end as a vendor. Here I am caught in the middle of it with yet again, a broken scooter which is what I use to get to and from work all summer long. Let me know what I need to do to get my money back as I have a lemon here and I will *NOT* entertain fixing this anymore. This is pure insanity and I’m tired of dealing with all these issues.
