Hello guys, I'm new to the forums and very glad I've eventually found it to share & get some knowledge.

I'm a programmer, hobbyst logic board repair specialist, currently working on a lime scooter you are trying to reverse This is an image - REGISTER or LOGIN to view.


I will share what I know and plan to do as I get home in the evening This is an image - REGISTER or LOGIN to view.
Looking forward to your findings. I'm trying to reverse engineer the controller board and make a custom firmware with open source motor controller. Only problem is that I can't find the time to work on this project right now.

How it works without GPS/GSM tracker? how company communicate with the scooter?
Communication is relayed through the renters phone ’app.
When a scooter is scanned, the phone communicates data and GPS with the scooter company. Over Bluetooth, the phone app relays the unlock/lock codes to the scooter.
This saves scooter company money because communication is carried on the renters phone data.
But its higher risk. The company only knows status and location of that scooter the last time somebody rented it.

Sooo evry one can easly steal Gps has easly 4 bolts that can be unscrew with torx 15/20 when you unscrew just make strong pull out and don't cut cables ! just pull it out with strenght take some screatch or paint in can and make the pipe black so nobody will suspect that it's lime propety . But in case take bandana and mask up so fbi won't find you that easly This is an image - REGISTER or LOGIN to view.

So I decided to give a try to chinese motor controller some of you have used. Before any installation, i wanted to connect everything to see if it works. Everything is connected correctly, but when i’m trying to connect the red ones to the battery (red circle), sparks are coming out, so i think i’m somehow short circuiting it. When i connect only the thinner red one (translated chinese manual says its „lock power supply”) there are no sparks and i have 4,9 V on throttle wires (green circle), but short circuiting them gives no effect, wheel is not moving. It doesn’t matter if i try to connect the thicker one alone or together with thinner, it’s the same effect, only connecting thinner alone „partially works”. Any ideas on what may i be doing wrong?

It's looking like to be easy hackable scooter, only need to know what strings is send via BT and you can repeat it again This is an image - REGISTER or LOGIN to view.

Hey there
So you should have 4 red wires all together

1 for the hall sensor power ~4.3V output
1 for throttle sensor power ~4.3V output
1 for battery power in ~41V input
1 for the ignition lock that has no voltage

If you're not using an ignition lock that cable can be connected direct to the 41v input wire that goes to the battery
I can't say I saw any Sparks at all when I was setting mine up so doesn't sound great

Once you have double checked the wiring you could always connect the two white wires together (the self study wires) and then connect the power
If the wheel spins you will know that the power , ignition, motor and hall sensor are working .
I didn't take a great photo of my wiring but you can have a look at this one

A thought. Since the company is able to unlock the unit remotely..wouldn't there be a way to do this locally or emulate the unlocking part via a 3rd party app?
Yeah, but I think a hard reset would do the thing to get out of the locked state, because you can change all the other settings, just not the locked state. A security feature made by Ninebot, and Voi took advantage of it. Now we just need to figure out how you hard reset the control board.
That would be even better yeah, agreed.
I have an unlocked VOI ES2 that rides when I plug the dashboard. So I'm out of this hassle and I just need to replace the dashboard ?
