A bit of reverse engineering on the serial protocol of the bike controller (they are all the same, AFAIK) could open up MANY interesting possibilities :)

The heading says it all. Solder according to the schematic and program the Arduino using attached program (adjust as needed, defaults work well for me). Should work instantly. You can put the Arduino Nano inside the controller case (insulate using shrinking plastic), in that case connect the...

Update: No joy. :( Now I actually took apart my previous e-bike to get access to the PAS sensor, connected the output to ZL1, ZL2 and various other inputs I could think of and it does not budge. Am at my wits end. Any other ideas anyone?

@docw009: This is exactly the kind of info I needed :D Thank you, thank you, thank you! Off to test it out :D

Thank you for that info, but I'm saving that for plan B and I would build it myself in any case (Arduinos FTW :D ). What I really need is an advice from somebody who's more familiar with these controllers than I am, I'm sure I just need to connect the proper pins on the controller board. These...

Hello, I'm a lurker here for a while, but this is the first time I need help that I couldn't find using forum search, so I finally registered. I'm working on my second e-bike conversion. I bought an e-bike conversion kit on Aliexpress, 500W geared hub motor with rim, 18A Bafang BBSX controller...
