Well, I guess it is time to show you my work.

Image

Once upon a time there were two Lime-S M1.1 (Lime Gen3 variant with e.g. two brakes, slightly different handlebar or simpler display). First one was found in the trash, without handlebar and with some wires cut and second one was standing for about 4 weeks in the park with bent handlebar and broken handlebar holder, after a tree had fallen on it. I gave myself permission to take them both.
The second scooter was my base. I straighten the bar and used handlebar holder from the first scooter to replace broken one. I successfully uploaded unlocked software to the controller and got 28km/h v-max.
I wanted to have cleaner look so i managed to take out the black box from the green box and put it inside diagonal pipe, just above the controller (first I removed sim card of course and disconnected the speaker, which annoys me). Yes, it fits there perfectly, you just need to move controller slightly down in the pipe so it will be screwed with one srcew only, not three. I covered the holes from the removed box with broad matte-black tape.

Image

I wanted to use the original display so I had to make the cable longer, now that the black box was much lower than before.
First I wanted to solder an extension, but then I thought that while black box will be just next to the controller, I will not need connector cable between them and I can use it as an extension cable. I needed 4 pin cable, and the cable I had was 6 pins, so it was just the matter of drilling 2 holes for extra pins in blue socket of black box. The solution worked.

Image

Additionally I wanted to have front light much lower, so I used light power cable from the first scooter to extend my cable and I put it in the fork tube so that the cable goes out of the opoening in the bottom. I took the lamp from green box and drilled a hole in the back and screw the lamp to front reflector holder.

Image

Now some switches: first I wanted to be able to turn on and off brake light and front light.
I soldered thin wires to front light power cable and managed to put them through a hole where brake line goes. On the bottom of brake lever I installed small lamp pull-switch (without a rope, of course), that I can move with my thumb.

Image

As for brake light I manage to solder the same switch to the brake power cable in the back and hide it behind the side of back wheel fender. I used a small homemede L-shaped metal part that I screwed with one of the fender screws, not to drill any extra holes in fender.

Image

I also wanted to turn off my scooter and turn it on without plugging the charger in. This thread helped me: viewtopic.php?f=13&t=6233&start=60 . I installed hidden switch in the bottom plate of the scooter. It is located on a cable that connects battery and controller. There is also a push button there located on a new "bridge" wire that connects original battery-controller cable with original chargerport-controller cable. Basically, when you push the button scooter "thinks" the charger is plugged in and starts. I glued and insulated both buttons with silicone.

Image

I spray-painted it matte black and gold. Glued some sandpaper to cover Lime logo in the foot plate. Glued little sandpaper stripe on the bottom of diagonal pipe to protect it from shoes.

Image

Glued some round furniture floor protectors to cover little lime logos on grips or damper tops etc. I did not like color led light so I cut rubber stripe with small round opening and screwed it to cover the light almost entirely and create neat colorfull dot. I screwed smartphone holder taken from selfie stick to one of four holes below the handlebar head.

Image

I plan to glue a sandpaper stripe on top of back fender to protect it as well. There are also some reflective stickers to be installed. And perhaps a little led light stripe on the floor;)

To sum it up - I am really happy with the result, especially since I had to learn many skills and concepts to get to this place.

Thanks for watching ;)

Your Scooter looks awesome :O

Which ST-Link adapter did you use? And did you connect anything to the controller except the adapter?
Can you upload some Images please?

Thank you!

I used most common no name ST-Link, I guess. I bought it in local electronics shop.

It worked flawlessly, no errors. Everything was connected to the controller when I flashed it. Charger as well, of course.

Hmm, okay... I have the same ST-Link adapter, but I get the same error code for every controller.

Do you also use Windows 10? And did you also connect the black box without a SIM card?

Am I just too stupid? : D

Yes, I used Win 10 laptop and took out SIM card from black box.I used this program:

Image

The pins are connected to the ST-Link like this:

Image

Basically they go to the controller in reverse order, so when you look at controller from this perspective

Image

brown goes to first pin from the bottom, then goes red, then orange and then yellow.

Thanks for doing the job of writing it all down! This is awesome :)

I actually did everything the same ... But maybe my controller is just broken. I will test it again with a different controller and hope that it works then :D

How did you get the screen working? Only the front and rear lights work for me, while the screen and the led under the screen are dead. Two days earlier it was still working, it showed speed, but the led was pulsating in red. When the controller flashes, my scooter runs for 1 minute and then turns off. :roll:

The last picture is taken from M20001 instructions. Check another controller and another ST-Link if you get errors, and let us know.
