Segway Ninebot ES4 Speed Hack - How To Unlock Speed Limit

Is your Ninebot ES4 limited on speed? Learn how to hack the firmware to unlock the speed of your Segway ES4 or ES2 electric scooter.


After upgrading an auctioned ES4 with a replacement dashboard, the scooter works and connects to the app but it will not switch modes when you double-tap the button.

Doing so just toggles the light, and whenever you turn on the light it activates the speed limit!

It does not however alter the LCD display which always shows the red-S indicating sport mode whether the speed is limited or not.

FYI the default functionality is a single-tap activates the light and a double-tap changes modes from Limit-mode (no S), regular-mode (blue S) and sport-mode (red S)

So now if anyone wants to use the scooter they cannot activate the light or it will cut the max speed in half.

Any idea how to fix this? Firmware has already been updated to latest.

Thanks

Sounds like you're on the home stretch to get this scooter working perfectly. Were you able to re-flash the firmware? Sounds like Bird has some funky code on the control board.

Replacing the control board with an original should fix the issue but will cost more waiting time and money.

Yes, the firmware flash brought it up to the latest according to the segway app.

I had heard that the Bird segways were not using modified controller boards like the Lime segways do. I guess that is incorrect.

I think it would be easier to just install a manual switch to connect the headlight to. Its not worth more than doubling the cost of the upgrade just to get the dashboard control of the headlight working.

So it looks like it is confirmed that the Bird segway ES-X conversion is a simple circuitboard swap much like the M365, unless you want a working headlight or need the ability to use non sport-mode.

Oddly turning on the headlight doesn't actually activate limit mode as I had suspected; the red S is still present and when I turn the limit mode down to the minimum setting in the app the max speed does not change when the headlight is turned on. Also the LCD seems to dim as if there is a power drain somewhere.

I guess for now I will use my Xiaomi when I need to ride at night and I will use this one when I need to go up a hill in daylight- it has slightly better torque.

you got a scooter with a faulty main control board. seems to be fairly common on the Segway ES scooters.

this link should explain more...

Yep thats it!

I salvaged another control board and problem solved! Still can't change modes but turning on the headlight no longer kills the speed. Could just be my imagination but it seems like the acceleration is better too.

When you say salvaged, do you mean, you pulled it from another bird scooter or bought it online?

I found this tutorial to fix it. Looks like it's as simple as replacing a resistor or fuse on the mother board

Could you post the link for the dash that you used? I also have a junked ES4 that I'm looking to resuscitate, but I've heard dash replacements are hit or miss. Thanks.

Try this to get the red or white S. Change the speedometer to METRIC/kph and tell me if you get the Red S. And on imperial for mph the white S.
