I decided to update my Opensource DIY EBike, mainly because I am using a better display now, a monochromatic instead of an OLED. This new one is much better to see on outdoors as also is bigger - I am being using this display and firmware on my Fiido Q1S scooter, since one year ago. A bit more...

My focus is being building an OpenSource modular system for EBikes and micro EScooterts, based on VESC motor controller + ESP32 board running high level fast development Python firmware. And I used wireless communication between them: - EBike/EScooter main board that connects to VESC - Display -...

Another user, 3D printed in clear plastic for the Bafang M500/M600 motor cover, and that red and blue LEDs from the EBike board, kills my heart!! 💕 The display is also great!!

On my Dengfu E10 frame, there is a button switch specifically to turn on the EBike. I connect this switch to the battery JBD BMS that has a specific connector for a switch like this. The JBD BMS switch is very important, because it switches the power on/off but in a safe way, avoiding sparks...

So, I am being riding my EBike, and here is a picture of a full day riding but with a lot of mud: I have some good news for this project: EBike / EScooter modular DIY OpenSource electronics and software 1. Wireless communication between the EBike board and display: There is a new Python...

The EBike modular DIY electronics and software, is featured as the Project of the Week on the Python on Microcontrollers Newsletter. This newsletter is written by the Adafruit Industries, an open-source hardware company based in New York City, that is popular among makers.

I just finalized the documentation / How to Build for my Bafang M500, I hope it can help others to replicate and learn how EBikes / EScooters works: https://opensourceebike.github.io/

I 3D printed the motor cover in ABS plastic - here it is, and just before I screwed it, I did put a fair amount of silicone to make sure it will keep the water prof: --------------- Yesterday I did a ride for 4h and it was a good test. Everything is working as expected. I was looking at the...

I do not plan to sell anything. The options are: - user is able to DIY his own solution - user asks to an electric engineer friend to do it - user asks on an electronics / EBike shop to do it

I did finalize the installation of the small VESC motor controller + EBike board, inside my Bafang M500. It works well as I expected, just like it did on my previous version with the external VESC FLIPSKY 75100. The final result is this one: And how is it inside?? Here it is, without that...

Display And I did finish the display. The schematic is so simple!! Only 11 wires to solder: I already tested and it works. Early tests showing the state of POWER, UP and DOWN buttons: It is not yet fully assembled because currently is waiting for the silicone to harden: When installed...

Detail of the squished silicone, after tightening the engine cover: I went for a test ride - it works very well: pedal very sensitive, fast response and high torque: I am not very happy the way that cables come to outside - I can improve that a lot. But, why bother if soon I may jump to have...

So, after the night, the silicone got hard as expected. Note that I also protected the connectors with silicone: And here is the very first test. I had to increase the length of the battery and motor phase wires, doing extensions. With that, all seems good: And now testing if everything...

The EBike board is ready and attached on the 3D printed motor cover. And here is the EBike board alone (including the magnetic encoder sensor green board): I wish to make the board robust to vibrations and water. Since I can program the board by wireless, maybe I will cover the board...

We currently have access as DIY to much more advanced technology than what the Ebike manufactures put inside. If you tell me 3 years ago that I would have an EBike with electronics that runs firmware in Python, and have Wifi and Bluetooth that let me develop and program instantaneously with my...
