Hi, With the torque sensor it is very different. You need to apply force to the pedal to start receiving electrical assistance. If you pedal without power, no electrical assistance is applied. Normally the panel shows help from 80w to 120w. If you pedal standing up, applying a lot of force...

Thank you very much. With your help I identified the correct wire sequence. I cut the wiring and assembled it with the new sequence. Now it's working. My engine was running backwards, and due to the clutch it was running but not turning the wheel anywhere. In the document you sent, there is...

The video in ZIP follows. In your opinion, is the engine with the wrong phase?

It's not the same, see the manual you sent me for the p850c and Advanced Settings doesn't have the same settings as the 850c. Internal speed sensor.

my display is p850c, it doesn't have these options in Advanced. if I keep accelerating for a while, even without the wheel turning, error 21H appears but i believe that 21h is because it is not increasing the speed. Do you have an email to send you the video? it really looks like it's phase...

it is not cracking noise. The noise same electric motor. I can't attach the video. says the extension is invalid. Does the forum accept any kind of video? how can i send you?

I don't have phase settings on the display. The engine starts and makes noise when accelerating, is the engine running backwards?

other information: Motor connectors are the same, plug and play, but how do you know the pin sequence is correct?

Information: The seller informed that the new kit was for the bafang engine, so I asked here if there were communication protocols with the engine. Is there really a mismatch? The engine starts and makes noise, but there is no force on the wheel. It seems that some feature to give the wheel...

Install torque sensor. When pedaling, the engine is activated, but it turns in false, it does not transfer the power to the wheel. This happens when I pedal or use the accelerator. The engine starts and makes a running noise, but the wheel does not turn. Any suggestion ?

Yes. https://a.aliexpress.com/_msUESkM

I did not understand. the old setup: controller torque sensor display motor new configuration: controller (new) torque sensor (new) display (new) accelerator (new) brake sensor (new) engine (old) the only thing that didn't change was the engine. tested using the accelerator, the engine...

Hi, all good? the new controller and display arrived and installed for testing. It works, but the wheel doesn't turn. am i doing wrong? my controller uses torque sensor, it's connected, but I haven't installed it on the bike yet. thanks.

I was wrong. Engine RPM is independent of gear ratio. right?

Great explanation. With this information I can calculate my gear ratio for better performance and durability. Best Regards.

Sorry, i dont see #24 above.

Sorry, i dont see #24 above.

I see, but the engine itself doesn't have a rev limit? I saw in some advertisements saying that the engine had 370 rpm.

I am back :-) Do rear engines have a rev limit? RPM ? Thank you very much for your attention. Knowledge is very valuable and sharing it is even more valuable.
