If you don't have someone to reprorgamm the controllers and aktivate the throttle, send the motors back...
Noone knows what parameter setup is on your motors...

This is another option if you're worried about metal on metal from a front derailleur

Sending 2 motors back to China would cost more than the motors?
Have sent 3 emails over the last few days to Amy about this, nothing back yet. They are useless without the throttle, both motors and both throttles (although the throttles themselves do work) it just has to be in the controller, it has to be programmed for no throttle.

I also have problem with a bafang 48v 500w bbs 02 from Amy.The motor dont work properly.It doesent give power and speed.It is less powerful than a normal bafang 250w hub.When I connect every thing
it gives error code 04.If I disconnect the throttle and turn the lcd display off an on again ,then the error code is gone.But the motor does not give full power and speed in pas.Also the motor does have very unstable rpm in eco and sport,but not in pover mode.Amy said she talked to the engineer and he said motor is ok.Throttle is the problem.I dont belive the throttkle is the problem,but I am waiting for a new one.So I will soon find out.I belive it is some problem with the controller or maybe the display?.Anyone had similar problem or any ideas?

Best e bike for me(I have 1000w cyclone & heaps of 500w parts & motors with stuffed controllers )& have nuvinci its great for town intersections that's all) but best is 500w cyclone still a light bike (throw it over a fence etc) but the controllers breaking down the best are single chain wheel kits as on the others chains come off shoe laces caught all sorts more things to go wrong ---we need a kit that has enclosed drives a real 500w & controller separate for easy replacement ---is bafang this kit---
for my clients who have my kits & myself there''s no better e bike than changing gears we have left thumb throttle right gears( all remade throttle) GNG has so many
exterior drives grass can't be very long where they made that kit

You got them from Amy, so get on here nerves. She needs to give that software for reprogramming away. I tried to get it from her, but she is not willing to give it away.
The stock setup is for pseudo pedaling singlespeed drivers and bullshit for everyone that is using gears...
Where are you from? We need someone in Europe that has the software and is willing to reprogramm motors.

hmmmmm I'm surprised nobody modded their kit for an external controller yet. that should solve a lot of these console firmware problems. :wink:

Well I took the bike out today for an actual ride. The motor feels nice and has lots of potential but is way slower and under powered compared to my 36v 250w mxus rear geared motor.
I barely got the bike on the flat with no wind to 14mph, had to pretend to pedal as the throttle makes no difference and does not work on either of the two motors.
I then placed an watt meter on the battery and it's weird, on the larger rear gear (as in for uphills) the bike pulls less torque and hits 5A to 6A but place the gears on the smallest rear cog and it pulls harder at about 8A to 10A and feels stronger? On the flat the motor does a little surge to about 8A then very quickly settles down to 5.5A to 6A as it approaches 14mph then goes right down to silly low amps.
I have the Bafang C961 LCD display on mine from which you can program certain parameters, I'm wondering if the throttle is disabled with this LCD?
Which controllers do others have with the BS01 motors?
I also read that the power is much better when using the throttle on its own....which is what I want.

Hello,
I'm new 57 old from Belgium doing electronics for 40years now and have a BBS01 36V18Ah
The motor is very powerful and I'm very pleased but:
the thumb throttle has only three stages
0, very low speed, and max speed.
nothing in between. thats very annoying and I already replaced the Hall sensor, disconnect the Pass, but no effect.
It would be very fine if someone could help to get in the programming of the BBS01.
Can anybody help? thank You very much.

I believe that mwkeefer has tested a BBS02 on an external 6-FET, but I don't know if that was a temporary test or a permanent mod that he is keeping.
I suspect that if you use a sensorless controller, you only need to hook up the three phase wires, but I have no evidence yet.
I have heard a lot of people on the sphere say the same thing, that these motors are underpowered why is that ? is it because it's a high voltage hence low AMP but consequently low Tourque motor on the Bafang ? I havent heard any cyclone or GNG owners say they are underpowered compared to a HUB motor ?

If it only pulls 8Amps that is the reason why it feels underpowered. The 350W version can pull 20Amps if you adjust that in the software (a french dealer that has the software tested that already). It won't feel underpowered on 20amps...
Normaly it will pull 18Amps if you use the throttle.
@Spacey: It should pull 13amps on level3 so there seems to be a completly wrong setup on your motors...
The internal Controller is quite nice if you got the software to do a good setup. It can do amp controll, that is much nicer to ride than a normal Chinese speed-controll-Controller like the Lyen. I don't see any need to replace it, also it is waterprove and you don't need to rewire everything... But we need to get ower hands on that software to reprogramm!

Nice! that is what this kit needs. I'll be watching this development closely.spinningmagnets said:

god if I have one of this kit, I would totally try this out with a sensor-less controller. I read that those bafang geared hubs performs well sensor-less, just like sensored. somebody gotta try this out!

The controller in these motors feels very nice and quiet as they are Sine Wave controllers as opposed to the usual square wave controllers.
Mine is exceptionally under powered, but I put this down to the throttle on both motors not being recognised by the controller. As a pedelec the power is barly ok, but double the power on throttle would be perfect....hope I can sort this out soon.
Have sent an email to Amy saying that I would like one of three things:
1: Software to reprogram them
2: New controllers already programmed
3: Refund

Nearly finished my rebuild of my Yuba Mundo with the bafang 750w with a twist shift.
Build is dead easy, basically like replacing a BB. Had one snafu with a cable not all the way connected, but sorted that out easily.
I know most of you are concerned with top speed, but for me it is the hill climbing as I have two nasty hills on my commute. My street is the ugliest as 22-24% grades. I run an 11-34 8 speed rear cluster.
So i took out the mundo to bed in the pads, stretch the new cables, and do a little battery conditioning.
The bafang handled my hill with ease at either about 3/4 throttle or 3 or 4 on pedal assist. I could simply spin up. That crushes my old DD Amped rear drive.
Still have to finish the battery enclosure, and a few other odds and ends. Will ride in on the commute tomorrow. That will give me the chance to run flat out a bit.
I will post some pics tomorrow if y'all are interested

I have just finished my real test ride.
13.5km with a some hill climbing and throttle testing to 40Km/h
and I used 4,055Ah of my battery !!!
Max motor power was 560w (on display C935) and on my logger 750W 20A.
I used lipo's 6s 5000mAh 30C. in my backpack as test.
I'm not really satisfied and need at least at battery of 36V20Ah to get an acceptable range.

in the leather bag, there is not enough room to fit a large battery.
thats why I made this.
I'll put a 36V11,25Ah Samsung ICR18650-22P battery in each bag.
22.5Ah that would be enough.

Does anybody know if parts are available for these. I was swapping my bb02 in to a different bike. Like a dumb ass I tried to drive the unit out on the pedal shaft. Not very smart. I busted the large spur gear through its plastic housing. Dumb dumb dumb. Anyways I'm looking for parts or someone who can repair it. Anybody have an exploded diagram?

There is a German disassembly video for the BBS01 at the bottom of this article, which is structurally identical.
