Hi, I have had my bike for 2 years now and only ridden about 300km since new. My last ride the torque-sensing stopped working. I have to pedal really really hard to get a small push from the motor, but normal pedaling does not give me any help from the motor. No settings has changed since this...

What model of battery do you use? I have the Reention Dorado battery that looks like this: https://sc02.alicdn.com/kf/HTB1ECmfaIvrK1Rjy0Feq6ATmVXa5/china-suppliers-Electric-bicycle-reention-48v-21ah.jpg With no handle, and it is 48V 21Ah. Thank you!

How did you test the BMS cutoff? I have a 48V 21Ah battery with built in BMS

I think it is time to create a thread dedicated for programming the Bafang Ultra 1000W. For reference, this is the default settings my new e-bike arrived with: https://imgur.com/a/g9q2X4J If this is standard for all Ultra's, I don't know, but it is a good reference point. I will start off with...

Got an update on my torque issue. Sent down the motor to Bafang in Netherlands and they found out that the torque sensor was broken. And they will send a new motor as a replacement. Thank you for the help when looking for the issue. I hope to experience the bike as it should be!

I got it connected, placed the bike on a stand and connected the PC and did a Continous Get while pedaling with my hand at a steady rate. Here you can see the result. In the first video I try to pedal at a steady rate: https://streamable.com/u19a2 And in this video I try to accellerate (pedal...

Great advice, I will do this today! I am using settings that other people have confirmed are good, like the settings in the video about programming. And I am going to connect it to my PC to check the torque values. What am I looking for here? What are reasonable values? And should I keep it...

I am not sure I understand? Can you keep the bike connected via programming cable and read out torque in real time? How hard should I pedal by hand and how do I do this?

Just got back from testing the bike. Was able to solve the throttle cut off issue too. This means the throttle works very very smoothly, as I was able to program the right voltage. However the torque sensoring does not work as I believe it should. It feels pretty bad to ride. Say I got an uphill...

No, mine is an Ansbern, this one: https://www.alibaba.com/product-detail/China-48V-1000W-Mid-Drive-full_60792141560.html?spm=a2700.7724838.2017115.49.576e643ecWbVUb The reason I am here is that this is the only active thread on the Bafang Ultra anywhere. And my bike and the Frey share many...

I will try it again tomorrow afternoon. I just did some testing in my house with the bike and I noticed a weird thing. The throttle I have on the bike which is this model ( https://electricfatbike.files.wordpress.com/2015/08/left-thumb-throttle-500x500.jpg ) will stop working when I go past 70%...

I understand that it might not be perfect on standard settings, but it feels like it doesn't work as expected at all. I actually bought a programming cable and I tested it with the default settings first ( https://imgur.com/a/g9q2X4J ) and then the settings suggested by...

Finally the weather is good enough to test my ebike which has a Bafang Ultra 1000W. I want to check out if anyone else has the same issues. The torque sensoring isn't working as I expected, it is very jerky, even if I pedal at the same rate the motor will turn off and on, shouldn't it be smooth?

I actually got some progress done. I managed to listen to the COM-port with a Serial Port Monitor application when I connected the bike with the Bafang Programming software. So I now have the correct response to be able to connect with com0com virtual ports. The connection request from the...

Would it be possible to modify the firmware in the DPC-18 to be able to do this by holding one of the buttons? If not, do you think this will work without modification on a Bafang Ultra? The display is the same I think. But the engine is different. EDIT: Just got com0com and HTerm setup, and...
