speed measurement magnetic steel number
- Thread starter Torch
- Start date
Never seen the term "speed measurement magnetic steel number". Best guess is they are referring to a wheel speed sensor, for the number of poles (magnets) on the sensor's magnet wheel, wherever that is on the bike (often inside the motor; for geared hubs it's often six, or one).
What makes you think it is set wrong? (What specific system behavior is not as you desire it to be, or has changed, that you could ascribe to this specific function, and why ascribe it to this if you don't know what it is for?)

I was given the wrong manual with the bike, when I went to set ODO back to 0 I messed it up because of wrong manual. The bike would not run I could not figure out what I did. I changed a bunch of stuff lol. got it to go much faster than originally programmed, but speedo and odo did not work properly. I got the proper manual and factory settings. but now I don't get the extra speed. the most I can get extra is 2mph. some of the information I got from the factual www. suggested this might not be set properly. I know little to nil about this. Is why I am here

Given where the parameter is in the list and the others around it, I'm still inclined to think it is a speed sensor pole count setting.
Does the speed reading on the display presently correspond to actual speed? (compared to say, GPS on your phone/etc with any of the apps out there for that)
If not, what is the reading you get on the display, vs the reading on your phone? You can use the ratio between them to calculate numbers to try on that setting. For example, if you get 20MPH on the display, but 3-4MPH on the GPS, then that's about a 6:1 ratio, meaning you should probably change the poles setting (if that's what this one is) to 6.
Regarding other parameters to get the speed or other desired results back: You would need to compare the settings you have now to the ones you had before. If you didn't write those down or take screenshots of them, etc., then you will probably have to experiment based on what settings you have available related to those results. (for example, there is a speed limit setting you can change first. more speed usually means setting the speedo and/or wheel size different from what they really are, if there is a separate speed limit in the system that you can't override or the one you have access to won't go high enough. Or setting the current limit higher (if your battery can take it) if the speed you want to reach takes more power than you can achieve at the present current limit. Etc.

The Chinglish reminds me of this passage from the KT LCD4 manual:
Which would mean it's looking for the number of motor poles, times the gear reduction ratio. That information is usually present in the spec sheet for any given motor.

Yes that is what I was looking at, Thank You I found the specs and have determined that the setting is correct

Just browsing some threads. Hopefully your enjoying your bike regardless of speed readout. I saw your question and my thought is that you should look at the wheel diameter setting if your speed magnets setting is correct. But I’ve also read that speed magnets in hub motors sometimes fall off. So that might cause speed readout errors.
