Bafang programing

[Sepia]

I have received my new Bafang BBSHD mid-drive uart motor and have had it tuned down to 75% of its capacity by the shop.

I have the programing cable and would like to change some of the parameters

Questions, what is the best and easiest program to use?

Has anybody done this?

Thanks

Thanks, yes, I owned a Bafang motor for 7 odd years, but never programmed it, sorry!
I guess Aunty Google and Uncle YouToob will help!
Good luck, interesting to hear your results, how you find it, etc!

Yes been there, done that hence my question.  There are so many sites with advice and some of them slate each other.  Much cheaper to have purchased from America than locally and just need to fine tune.

I need to tour on  my bike (two batteries) and have an extended PA range as I do not need speed or power etc.  It is not called pedal assist for nothing.

Some food for thought ....

 

Three things DRAIN the battery :

. Hills

. Head wind

. Speed ....

 

The irony ... ride a race where you use the group to draft and reduce battery use from wind .... with these groups you often exceed the assist speed limit, thus riding fast but not using any battery power.

 

My first Winelands race I got to 60km and realised had used about half a battery ... expecting to be near empty on the battery. Turns out that in full race mode I spent so much time above the assist limit that I was using less battery.

 

You can drastically increase your range by the following software settings:

- reduce the assist speed to 25km/h.  You will still be going faster on downhills, but not use any battery for this

- set eco-mode for minimal assistance on level roads ....

- now use gearing and minimal assist to get up the hills.

 

One last thought ....e-bikes like SPINNING .... no not spinning the wheels, spinning the cranks.  Low torque (minimal battery) but high revs.  This takes a lot of getting used to.  But if you can cycle at 85+rpm on level roads and up that to 95+rpm for hills, you get the best out of the motor for minimal electrical assistance. But man-o-man .... the lungs needs to get used to this ....

Thanks Chris

I think I have eventually managed to get the program right with the least amount of battery drain.

It took ages with trial end error.  The program I used was very unstable and had to keep coming back.

Now what to do with my old motor setup which is still working.
