Hey guys!

So, it seems that the sim card device is actually connected via bluetooth to the scooter.

Basicly the lime scooter is "loked"
Ha ! Thats clever.
Really obvious and decently secure method now I think of it...
One would need a method to flash that portion on its processor to defeat it. Otherwise fit a replacement control board...

Guys, you can confirm that Bluetooth connection theory?

I'm thinking to replace dash and motherboard from original ES2. The only thing that bug me about , it's the original battery have a 4 pin connection to the motherboard, and Lime's have just 2 pin connector to charge port. All the others connection could be rewired normally.

Another alternative it's buy a generic controller, throttle, and dash. It's possible to find even a "kit" on Ali

After feeling disappointed with the difficulty level to convert Bird's first generation scooter, the Xiaomi MIJIA M365, to a personal scooter I've started to look for a new project. You can check out the Xiaomi MIJIA M365 project here.

My sites are now focused on seeing if I can do the same thing with Bird's second generation scooter, the Segway Ninebot. The expectation is things will be more difficult this time around since both Lime and Bird have the same scooter model in their fleet. I'll be attempting to convert both companies scooters to function independently from the Bird or Lime platform.

I've gone to eBay for sourcing the OEM parts from China. Unfortunately, I'll be waiting until late December or even January for them to show up. To view images REGISTER or LOGIN for full access.


Here are the parts I purchased and will keep this thread updated with my progress.

Looks like the ES4 has some new way of wiring that doesn’t fit the motherboard you purchased. So it definitely won’t be plug and play. But I’m sure a new clip can be added
Yes in deed, I did found an abandoned Lime, looks like a ES2, don't have a external battery just a GPS module in front and this is the motherboard that I found.

1. Charging port
2. This is connected through the tube to the lower part of the scooter
3. Dashboard connection
4. Connection to battery
5. Goes down through the tube to the lower part of scooter passing by a long rail just in front of battery.
6. To battery
7. That cable was unplugged. I assume to connect directly to a kind of programing interface.
8. That cable goes to GPS module, I assume one of them brings the signal to the motherboard to turn on the scooter.

And this is the GPS module

As you can see the circuit on the left holds the SIM card

Connection description

Pink arrow cable comes from motherboard.

Yellow cable it's the connection between that circuit and the big circuit to the left that holds the SIM card. I assume the white or the orange cable says to other circuit turn on the scooter.

The red arrow cable it's unplugged cable that I found in the back of module. I assume for programing.

So now I ask.

There's any way to replace the motherboard of this model? It's very different than the original one.

Or just run a jumper wires from one side to the other two complete connectivity and omit the SIM card entirely?

The screws on top of the Bird brain are T6. Here is a post I did the other day on the parts purchased to do the Bird conversion. Jump recently launched in Atlanta as well so I'll be trying it with them too. Unfortunately the parts are now going to be here on Jan 10th. To view images REGISTER or LOGIN for full access.

From post #3063

I purchased the stock parts below from eBay to try and convert it back to a personal scooter. They come from China and it'll be end of the year or later before they arrive. Also, you'll need a security screw driver kit to disassemble the Bird.
