Does changing the Display settings

[Nvreloader]

Guys
I have been reading all the posts in reference to the display/controller settings (Smooth etc).

When you change these display settings, to what ever,

Does this also change the walk assist settings?

My inclination would be to say no.

No... it's a hard-coded setting.
at least it is on the BBSO2B

Guys,
Another questions for you on this smooth setting/controller changes, etc,

Does using 2 wheel magnets make a difference?
The second magnet may make reading better?

My bike is stock, one magnet. I've seen a second mentioned, but have no idea why it would be needed.

Thanks A Hicks
I read somewhere that the second wheel magnet gave better/more uniform readings, trying to find that info now.

I'm left wondering if you aren't trying to fix something that's not broke? Could be there's been a change from the early motors to the later?I've seen the dual magnet thing mentioned a couple of times, but have never seen any detail. My reading are nice and smooth. No jumping around at all, so little concern here....

I am not attempting that at all........
With all the reading I have done on setting/changing posts,
I have never seen any information about using 2 wheel magnets.

It is a simple QUESTION, why not,
they are using/trying everything else, when they change the OEM settings etc.

I know you have changed your OEM setting, do you have a second wheel magnet?
it wouldn't take but a few minutes to change the wheel settings,
and test for a couple rides, since you are happy with your setting now.

If I had all the plug in's etc, I would do it in a heart beat, I am curious that way..........LOL

I am just about sure, I'll have to do some changes as I have found a mileage/speed setting errors,
on my Wart Hog/510 motor and settings.

Thanks

I too have read a few lines about people trying two or more magnets... from what I remember it left me with the impression to not bother... especially since my speed sample rate seems to be multiple times per second.
That said, I'd be interested in what you come up with if you are feeling foggy.
@m@Robertson if memory serves... you may have tinkered with this.

Wife and I went on one of our 20 mile runs yesterday, exploring a pretty impressive ($$$$) new connector between 2 existing trails within riding distance of home. Anyway, her bike is using an aftermarket KT controller, mine of course the Bafang. Our milage for each was within .3 of a mile on the almost exactly 20 mile run. That's plenty close enough for me....

If you want to install a second magnet, go for it! Those settings should be available in the display. I doubt there's any need to get into the controller setup.

You asked, that's my answer.

The reason for this question was,
I found out that my bike has an big error in the mph and speed reading, both readings are faster,
as compared to my Garmin GPS, speed is off 2.3mph. Yes, my GPS is very accurate,
as I have plotted/tested it against known Hiway mile markers and RADAR units etc.

So it appears, I'll have go inside and make corrections in the settings etc,
to get everything as close as possible.

With the 2 replies, which neither has tried it, but they say, "not to bother and close enough",
so that leaves an open door and an unanswered question..........JJOYC = just jerkin on your chain.
We can't have an open door letting the Cold or Hot air blowing thru it.....Can we? LOL

My speed and milage is very accurate and when compared to my Cateye the speed was dead_on and the mileage was negligible over a 20mi. ride.
My curiosity in trying two magnets was more for other implications in how the input influences the controller.
So since I don't have a need and you seemed to be convinced that it will help your poor setup.. please go through the door and give it a try and let us know what temperature air you get blown with.

Now you're making more sense. Nothing to do with 1 magnet vs. 2. I think you need to consider changing your tire size in the primary setup of the display. If that's set incorrectly, it's going to do exactly what you're describing. You may never get it exact (due mostly to small diameter differences in make/model/size of the tires in use) , but thinking you should be able to get it closer than what you have.

I've done a lot of poking around in the controller settings, and I don't remember any fine tuning available for small differences in tire size there. -Al

I finally found the app for use on my android phone, but can't find the connection cable etc.

When you set the wheel dimeter do you use the circumference around the outside of the tire,
or across the tire diameter?
Tia,
Don

 

[AHicks]

I'm told tire diameter, but I just went for the 29" setting and that's been working well. I've never confirmed it with a GPS though.

Yes I did. It works great until it doesn't, and thats when I learned how the BBSxx has a fair bit of fault tolerance built into its algorithm (the system recovers transparently from bad magnet passes), that is reduced by the same factor as the number of magnets you add. With a 32 spoke rim, I was able to use 4 magnets, but I had to take it down to 2 to get bulletproof readings. At that point the increased sample rate was so small it wasn't worth bothering with. In the end I proved wrong the people who said it couldn't work, but thats it.

So the question is:
Do you guys enter the manuf wheel size", or do you actually measure the diameter of the tire?
I have a manuf spec 26" wheel, but my tires are actually 30" inflated. And on my Aventon I have 27.5" by manuf sepcs, but after installing 3" tires, my wheel diameter is 28".

 

[AHicks]

Best answer I can come up with is to set it to best guess/SOMETHING, then check your accuracy (with your GPS) and correct your best guess setting as required to get it as close as possible. EZ peeze!

I think mine is set to 29" and I'm running 27.5" rims (actually the same setting I was using with the 26x4 fatty setup).....

 

[greeno]

For the tire settings in the display menu measure from the ground up to the top of the tire ( tire diameter ) and your good.
Mine is a little different as I have a 29" in the front and a 27.5" in the rear. I just split the difference and it gets close enough.

Another trick ( if you need to ) is if you don't want the speed cut-off to kick in at the 20mph limit just lower the tire size value, like set the diameter to 16 or so.

Speed is calibrated for the display and motor by how many revolutions the magnet turns on your wheel and a predetermined value for distance traveled on a set diameter amount. Smaller wheel equals less distance traveled as compared to a larger size.

Your displayed speed reading will be off, but you can get to a higher actual speed without the motor assist shutting down as the controller thinks your going slower.

I just measured my tire size, had the bike standing straight up and down, measured from the floor to the top of the tire,
thru the axel center and it measures 30-1/2" tall, for my 26x4.5 tires filled to 30 lbs.
Waiting for the connection cable to get here so I can change the settings etc.
