Does it work with these new ultra's? The green plug isn't round any more.

We need to keep on this and let others know about these problems. That way people will buy other brands if Bafang doesn't help us with this.

I have a new ultra display has tire size and diameter setting? Tire setting only allows 26 or 27. Then after the next setting ask for tire diameter. My tires are 27.5x2.3 what would I enter for these settings? Also there seems to be no place to change assist levels. It's set to five I would...

I work with China on things and I was told this is the device we will need to do Canbus on these bikes. Does anyone no if this is so?

Anything on Canbus protocol yet. These ultra's are dangerous the way they are now to ride and very uncomfortable.

Nice read but still didn't answer current settings.

When I first tried this bike I pushed on throttle pulled a wheely almost run into building. I ordered the programing cable. So I'm definitely going to change some settings. If you lower the current settings does the lower the power and watts of motor? I'm going to try some of the smooth...

So how do they say the m620 is 36 an 48v?

I'm getting this bike with a 48v battery. I have a 36v battery that will fit. I would like to use for a backup. Can I do this and what would I change to make work? Also can you change wattage use of motor to get longer rides when on mainly level ground. And how would I do this? Thanks

It has a bafang dp.c18 display and ultra motor.

using 36v on 48v setup . I ordered a 48v bike. I have a extra 36v battery. What happens when you use 36v bat on 48v bike?

I've ordered a m620 bike with 21amp battery. Can I program it to lower wattage? And would this give me more range?

Bafang m200 motor change out. Is there another model bafang motor that can fit in place on my m200 that has throttle?

I thought that bafang would finally chime in and tell use how.

I asked this over a year ago. I was wondering if there is a bafang controller that I could replace it with to get a throttle.

Could I use this to regulate the speed by putting it inline with battery? https://www.amazon.com/RioRand-7-80V-Motor-Controller-Switch/dp/B071NQ5G71/ref=sr_1_34?dchild=1&keywords=dc+voltage+reducer+40a+adjustable&qid=1600096003&sr=8-34

And thanks for the video.

Is there something I could put inline on battery to turn the watts down? My level 1 is still very jumpy and fast.

I don't know what kind it is. It uses a ring with several magnets that pas a hall pickup.

My mid drive works great but my rear hub is very jumpy when you use pedal assist. I have set different levels of assist and even in 1 the bike will jump when you start pedaling. Doesn't seem any one knows how to program a hub model. So I was wondering if any one knows how I could put something...
