After quite a few changes to my Ninebot Max Scooter I am now completely satisfied with its performance. Here I show everything that I have done to it. I have ridden 1800 miles in total so far on the Max. Something I forgot to mention in the video is that the software needs reflashing along with the additional 12v battery that is all part of the My Max Mods kit. This was a simple task and there are plenty of videos online about how to do that. The reflash is essential to get the best out of the modification, also the reflash alone even without the extra battery improves the performance greatly.
Here are a couple more notes. The rear tire wears out after about 1000 miles, the front lasts twice as long. I would recommend only original CST (Chen Shin Tire) replacements as they have an anti puncture sticky goop bonded to the inside of the tire tread area. You should never get a puncture with these tires.
With the Monorim front suspension if you tighten all the 6mm screws in the normal fashion, you will damage all the bearings, For each pivot point there are two ball bearings pressed into the suspension arm from either side. The problem is that there is a gap between the bearings in the middle so when the screw is tightened, it simply puts side force on the ball bearings and damages them immediately making the suspension movement notchy. I replaced all the ball bearings (from Amazon) and added shims in the middle to prevent this damage. Its difficult to describe, I'll probably do a video on it.
