Bafang Ultra Drive programming

[fambo1]

has anyone figured out how to get the ultra to perform properly

Most of the problems I see on the Internet about connecting this software to a Windows computer have to do with the COM ports.

The software for this motor was written for windows 8. Quite often, when using windows 10, you must right click on the program and select run as Windows 8.

if you save the software after running the program, the computer will remember this and run it in the windows 8 mode the next time you start the program.

When the software is running correctly in the windows eight mode, it will automatically search for a comport and connect to it, setting the baud rate to 9600.

As the computer is talking to the bicycle controller, the blue LED in the connector will flash.

I just sold my ultra drive bike. I was attempting to show the buyer how to use the software, but could not get it to connect. The BBSHD software connects with comm 5 but the ultra drive software gives error message. I tweaked settings on ultra drive once, but now cannot connect with the ultra drive software. Anyone else have this problem?

Have you figured anything else out yet to make it work as it should?

I haven't had it back out due to snow. In theory you should be able to start on a hill with the throttle to get going then goose the pedals to engage the motor. I'll see if it works once the snow melts.

Can anyone provide me with the latest Bafang Ultra programming software? Please send me a PM with a link. The one found on OP's link is very old.

Sounds good. Snow melted here so I was able to do some hill climbing on a short but steep hill. The results: the motor kicked in and propelled me up the hill only after I goosed my pedal cadence on flat ground before I started up the hill. In that case I could feel the motor kick in and accelerate before the incline and remained engaged up to the top. . On the other hand if I started up the hill without the motor accelerating on the flat the motor would not kick on during the climb no matter how hard and fast I pedalled. Back to the drawing board.

My brother had his BBSHD out there too. What a joy it was!

When I get my bike back out this spring I'll check my settings and we can compare.... Hopefully we can come up with something that works between us

The ultra is a dog... It's tourque sensing it is nothing like my bbs unit
just adjust your min cur to 3% and it'll be better
Karl's special sauce is a joke... I don't think he even tested a tourque drive

It sure seems like a dog which is hard to believe since it's an "upgrade". I moved my min cur to 3% but with snow on the ground it's hard to test on a hill climb. Still seems inconsistent on flat ground, motor kicks in sometimes but not other times. Throttle is weird too. Sometimes it's a sloth on the throttle and other times it excellerates. Hating this thing!

Does anyone know if the Bafang Ultra can be programmed to perform like the BBSHD on hill climbs? I use my bike for hunting and want the motor to do the work like the BBSHD does. In short, I do not want to exert myself at all and sweat. The stock setting on the Ultra is terrible for my application. Not researching deep enough into how the Ultra performs was a big mistake. Anyway, I have the programming software and have done some experimenting but am not there yet. The factory is no help and Bafang did not respond. I’ve researched but have found relatively little on the Ultra. Karl’s Special Sauce was not special for my application nor was the youtube video that is out there so I assume these reprograms are more for sport/trail riding applications.

Anyone have any guidance or suggestions?

Thanks

I have not changed any settings on the new mid drives yet, but they be able to be "de-tuned" to 200 watts.

The state of Michigan in the U.S.A. wrote new regulations for e-bikes, rendering my 1500 watt bafang mid-drive bikes illegal to ride on the street. As long as I'm not riding like an idiot, no one will know they are illegal, and unless law enforcement is up to date with the regs, and REALLY bored, I doubt I would ever be bothered by the law.

moved all the min cur % to 3 and its way better...

[ozzy]

Hi do you know if these motors can be programed to 200w to be legal in australia

[vtdownhiller]

I have reprogrammed my Ultra 750w a lot and haven't found any settings that I love.. Karl's is way off on the torque settings, best I found was
