Programing Adventure controller

Hello

I have been researching reprogramming my Aventon adventure ebike. I want to reprogram power assist levels, voltages, etc.

I have the phone app but most of the settings I want to change are not (apparently) available.

Is there a usb programming cable that will interface with the controller for a rear hub bafang 750w motor? Using this method, I should have full access to all the parameters.

I am not finding any discussion on full programming of the Adventure controller.

Can someone tell me what they know on how this is done and provide a link to any discussions and cables needed?

Thank you
 
I do not believe that is possible. Not sure which controller on your model, but I have not seen an OEM program or aftermarket program to change those settings. I ended up purchasing a more powerful, programmable controller for my Aventon Levels
 
I have found alternate methods of programming the controller. It appears however, that only a few features are programmable using your phone in Bluetooth connection to the controller. Many of the manufacturing parameters are greyed out and cannot be changed without changing the controller and most likely the display
 
Yeah, pretty sure they have that locked down. Hell, I asked Aventon a question about how many amps the Battery BMS was and they refused to tell me.
 
What you want to change is built into/contained in the controller. The fact you have a Bafang geared hub motor has little to do with it. What you are likely reading about are the Bafang mid drives which have a built in controller. Some of those (the UART based) ARE programmable.

Most hub drives, no matter the brand, use controllers that are NOT programmable beyond the absolute basics, like wheel size for instance. That makes the aftermarket controllers pretty popular. Check into the KT controllers for instance.

Most likely because they don't know....
 
I have considered a KT controller but I will likely need a new display.

The replacement controller is not likely to fit in the tube frame.

That's one possibility. The other is there might be one that WILL fit. Lot's of variables make it difficult to predict without knowing the dimensions of the area you are working with and the existing controller's dimensions.

There is no doubt the KT, or any other aftermarket controller, will need a compatible display. If going KT, I doubt seriously that you'll miss the one you have now, and they aren't THAT expensive, especially when purchased as a package with the controller.

Absolute worst case is you have to mount the controller external. That's been done, neatly, over and over again!

Have you checked out the dimensions of the KT-22a? If going EXTERNAL, check out the KT-35a. With that, you will very likely pick up not only the ability to program, but also a pretty significant performance increase. Worth mentioning for sure, any of these are going to require some DIY ability. There will be no plug it in and go option.....

Great advice, keep it coming!

Has anyone replaced the 46 tooth crankwheel with a 54 tooth and adding a few more chain links?

I did. I found myself frequently spinning out while pedaling in the highest (8th) gear on my Aventure. I replaced the 46T chainring with a 50T and it's an improvement though I wish I went to 52T. I did not see an available 54T.

Replacement was easy with crank removal not necessary. The existing 120 link chain still worked but it was definitely at its limit; I added four more links and two SRAM PowerLink connectors. The required chainring fits a 104mm BCD (bolt circle diameter). I bought this one in black: DECKAS 104BCD 40T 42T 44T 46T 48T 50T 52T Narrow Wide Chainring Single Chainring for 8/9/10/11-Speed (Round)
 
Has anyone adapted this to the Aventon Adventure?

Will the connectors have to be modified and how so?

I think some modifications in the way of wiring connectors is going to be a safe bet/the best assumption. I can guarantee there will be no direct plug and play available.

How so/what will need to be changed? Impossible to tell ahead of time.
 
Programming such things always were something complicated for me. Even after years of work in this field... But I'm not sure it's possible in such a situation (hope, the tips shared here will help you). I was really bad at math so a lot of my study tasks during uni were done by other people or this source https://plainmath.net/textbooks/8-calculus-graphical-numerical-algebrai and I was sure that I'll lose this fight. But then understood that it was just a stereotype. Math is connected to programming on a surface level...

The KT conversions are WAY more about fairly simple wiring circuits and WAY less about "programming". Still, it helps to have a positive attitude going into ANY DIY project....
