Bafang RM G060 Fat Bike Motor Differences

I'm currently designing a new electric fat bike and am looking into the Bafang G060 motor (also referred to as MG60) as an option for the drive unit. On their website there are 4 different version for the G060: RM G060.250.DC (rated power 250 W) RM G060.350.DC (rated power 350 W) RM G060.500.DC (rat...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Thanks for the quick update and fix for my problem casainho. Just made my first ride on the 0.54.0 and 0.6.7 and it has been great! One thing that came to my mind: I read somewhere that there should be an option to configure a minimum torque level for the assistance to kick in from still stand. Eg. ...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

SW102 new firmware release The previous firmware version on SW102 had a problematic issue where the configurations and other settings were not being saved and I was able, finally, to correct it. Hi casainho, I just installed this update since I had been waiting for a fix for the configuration bug. ...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

casainho, have you found out yet why the new fw for SW102 does not store settings? Currently I cannot use my bike because I installed the new motor and display fw before I found out about the issue. I have a lot of settings to configure after every start up (36v system)

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

So is it correct that the development for SW102 support is currently on hold?

Who was the main contributer? geeksvile?
He has not made a commit since early November and not posted here either. Did he mention somewhere that he has left the project?

Re: TSDZ2 mid drive -- Flexible OpenSource firmware (Casainho code only) for TongSheng TSDZ2 mid drive motor

That is a known issue. On latest version of firmware (for 850C only currently), that issue should be solved, on that rare case the system would restart. Thanks casainho for the quick response and for all the work you've put into this project in general. Really appreciate it! Could say a bit more on...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware (Casainho code only) for TongSheng TSDZ2 mid drive motor

Today I had a scary experience with the stable 0.19 FW and a SW102 display. While I was riding I noticed the motor was constantly giving assistance even though I was not pedaling. Display showed some error message (only thing I remember it had a file state.c in it). I tried to turn off the system on...

Best motor for throttle only usage

I'm thinking about doing a custom build of an electric moped after riding some electric scooters. I really enjoy the acceleration of these things. The idea is to use a bicycle frame, remove the drive train and pedals and add a strong electric engine with a throttle only. Now since there will be no h...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

I just did some first test rides on my TSDZ2 + SW102. Works great so far. However when I start pedaling from standing still I need around half a crank rotation until motor power kicks in. Is that normal? I thought the TSDZ2 would kick in immediatelly. Is there any setting I can use to influence that...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Then I would say you have a faulty unit. I’m afraid so.. however it will be quite hard to return with the cut open side :lol: It could also be that something went wrong during the first flash attempt. I remember it failed with some weird error message. Maybe it corrupted some part of the firmware? ...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

I would say you have no connection on SWD pins. Verify again your connection on SWD pins to the SW102 and try again. I just removed the soldered wires and tried with the solderless method using a 2mm 1x4 pin header. With that method I could not get a connection. Then I soldered the wires again and ...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

So I've just tried the flashing again. The device is still not coming up after the routine. Everything looks pretty similar to the screenshot in the wiki entry, however I've noticed a slight difference (marked in the picture below). In the wiki screenshot this line says: info : nRF51822-QFAC(build c...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Presuming that this is the initial flash (of the bootloader and v0.19.x firmware via the wires). On the initial flash, after successful completion, it is supposed to start running a simulator and display as if it is connected to the motor, which it did for my case. If not, sounds like something wen...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

I just flashed my SW 102 according to the wiki. The log said everything went fine but the display does not come up at all.. is there any way to check if the display is working without connecting the motor? Should it come up when I connect the ST link v2 3.3v and GND or do I have to wire the display ...
