Bafang Ultra Alternative Settings For Basic, Pedal Assist & Throttle Handle..

Ultra software - w/torque tab. Otherwise it's functionally the same as the BBSxx drives.

The optional display I'm considering is the 750c. It has 2 things I like going for it. It's mounted horizontally for starters, and the watt meter is larger and easier to read. Like the difference between 75w and 250w for instance. That's where the majority of my tuning is taking place. I'm used to a real time digital read out when riding the KT controller display equipped bike, so I lean on that a lot. Even basing my PAS levels and what gear I'm in on that reading. I guess I'm kinda anal in that reqard.....

I'm a little shy about writing something up that I've found works for me personally. My point is rather than take a shot gun approach, identify specific problems you'd like to take care of. I'd personally be happy to give anyone asking about a specific problem a hand - if it's within the range of something I've messed with anyway. I'm sure others would be willing to share regarding individual problems they've run into and managed to fix as well? Nobody has done that yet, that I've seen anyway. Everyone is writing up these big posts with multiple screen shots - without saying anything about their riding preference or what the focus was that led to the changes they made. -Al

that's good to know you could help someone if they ask :cool:, the main post I put up in this thread were the settings from the biktrix bike which has the ultra motor, they claim that their settings make the bike smoother.

I suppose trial and error is the way to go for the type of riding that person does

I ran into a huge mess over that claim. It cost them a sale. My credit card was on the desk ready to buy a bike. I asked their 3rd level of support for my options regarding custom programming, and was told there was nothing available, that the bikes were shipped as they got them. When I published that tech's reply in the Biktrix forum for discussion, the stuff hit the fan. I was accused of incompetence, my ability to read plain english comprehensibly, stealing company secrets, and begging to get something for nothing. That was the end of that. I bought my Rize for a thousand less and haven't looked back....

The solution might be a little trial and error, but you'll be working within just a couple of parameters, not the entire contents of 5 tabs of parameters. -Al

no that's crazy, them guys sound nuts haha they won't get far with support like that.

I suppose the thing we will have in common is the Bafang ultra motor, you sound quite happy with this motor after some very slight tweaks, i hold high hopes for when i try mine out, due to me not being able to try before i buy and having to wait over 16 weeks up to now all i have been doing is reading so many diverse comments and not knowing which ones to believe is a nightmare, i look forward to adding my own personal riding view

So what is the max rpm the ultra can run at before overheating? I am a few months out from getting my first ebike with a Bafang ultra. I'd like to program it to go past 20mph on throttle only. Chainring is 48T and gears are 12,14,16,18,21,26,32. With 26x4.9 tires. 48v21ah battery.

Not sure of the Ultra rpm potential, but the overheating will most likely come into play regarding the load you have on the motor - which can easily be seen real time by observing the watt meter. I believe it comes standard with a built in temp sensor that will start turning down the power when it gets hot....

The motor as you get it will likely be capable of blowing through 30mph pretty easily. Wether it will do that out of the box, or you'll need to play with a couple settings in the controller software (using a lap top and programming cable) will be the only question.

Where would I find the speed limit for throttle in the programming software?

Supposedly this is the penultimate source:

I am a Mac person and have no windoz machine and wouldn't know what I was doing anyway. I too have an ultra motor bike headed my way. Sposed to be here inside a month. I eagerly look forward to finally being able to find out just what it is to use this motor and whether or not I can live with it. If it's really bad I'm going to buy a motor from Wattwagons and switch it out. Then send the original motor to them to have their controller put in it. Always good to have a replacement motor lying about. Yes it's a crippling expense but dang it I want a bike I can love.

Go to the link below and under the "Basics" tab, check out the comments regarding "Limit Current(%) and Limit Spd(%)".
Then, under the "Throttle Handle" tab, check out comments regarding "Speed Limited"


Reed, maybe you already know this, but that controller that WattWagons installs uses proprietary software for programming. Check it out! YOU will not be able to make configuration changes using the programming cable like you can using the stock controller (using open source software). You will likely end up paying somebody to make an update file that will include the changes that you want to make. I think it's a safe bet those are NOT going to be free.

Too, Penoff's software is top shelf, but it's geared to the BBSXX series of drives, which will work on the Ultras - but does not include the tab used to program the Ultra torque sensing. -Al

Thanks. that cleared up only part of my question. That tab for speed limited only goes to 40kph. How do i go past that?

I think that answer is going to depend on what display you are using. Without looking it up, I believe the DPC18 I'm using is set for 99mph.

The bike will indeed have the DPC18. I know there is an advanced settings menu to change the speed limit. I have only seen that go as high as 40kph/25mph. So is it necessary to program the display instead of the motor? Or both?

I don't have the specifics in front of me, and even if I did, you would likely forget my answer by time you get around to programming. Trust me. There's nothing to prevent the motor from going as fast as it's able anywhere in the programming.

In the controller settings you can set the top speed to a specific number or to By Displays Command. If you set it to a number it will ignore what ever you set on the display.

I guess I'll just revisit this when the bike arrives. Thanks for the info 👍

Latest Bafang Ultra software is here. Link is one paragraph down the test.
