Original Control Board Replacement for Segway Ninebot ES1 ES2 ES4 Electric Scooter Mother PCB Controller Assembly Electric Kickscooter Motherboard Kit, 2.0 Upgrade Version

This seems to work well and be of the same quality as the original board. It was a tight fit but with the help of some tapping was able to be slid into the tube. I have rode a few miles now and it works fine.

Didn’t have any issues with this, I installed it and it indicated it was an ES2, but I have an ES4 so I just flashes the firmware to an earlier version used the Scooter Hacking Utility app then used hacked ES4 firmware from a website. Only issue was it was mad about my ES4 battery but after detaching and reattaching it worked fine.

I was skeptical at first, but once I got it installed, it worked perfectly with my external battery ES2 turned into an ES4 with the extra battery. The original control board, for some reason, kept kicking out a fault code. This new control board fixed the issue. My scooter is as good as new. I did, however, have to take the gooey strips off the side to get it to go into the tube. Otherwise, it is a win-win.

Ordered the control board and it did fix my problem however my scooter would not charge. I took it all back apart and inspected the charge port only to find the two pin connector on the board was flipped around. I unplugged it, flipped it 180 and everything works well now. Inspect your new board before installing!

First of all these are not waterproof. The first one I bought is missing a pin connector on the circuit board. The pins are there but nothing to plug into. The second one doesn’t work at all. The scooter won’t power up with either of the two controllers. I put the original one back in, and the scooter powers up. I will have to it a factory part from Segway. I have a little credibility here too. I have been a master mechanic on Lexus vehicles specializing in electrical. I am so ashamed I bought this crap.This POS probably cost 2 bucks to make.

The new components are working fine and installing the part easily

Had a problem with the board, they replaced it with no questions asked. Excellent customer service. Will buy again. New board works perfectly.

I don't know if this is the issue or not, but my scooter still doesn't work after replacing the board and the controller. There seems to be a 2 pin connector missing from this controller and my scooter doesn't accelerate at all. Brake trigger works because my light flashes but the accelerator doesn't work. Could be my throttle switch but I don't know. I don't have an error code.
