Just wondering if any of you had this issue so far ?
I’ve had this almost with every motor and it’s always been the pedals. Repeated poking grease into the bearings can sometimes cure it.

Re: New "TSDZ2 Torque Sensor Central Motor"

So I have had yet another motor fail on me, this time I was able to diagnose the problem. It's the controller. I connected the motor unit to another controller and it worked fine. I just need to switch the controllers. I understand you have to remove the cover on the drive side and then 2 screws. T...

Re: Bafang 850C color LCD -- Flexible OpenSource firmware

Despite using my fingers to maintain electrical contact whilst programming the LCD3 display I can’t recall ever having odd results, at least not like with the 850C. Is the boot loader reliable? My hardware is hard-wired unlike the LCD3. I’ve reloaded v0.5.0-beta.3 which was jumping all over the plac...

Loaded 850C_v0.5.0-beta.5. Imperial setting still not working. Even though main screen says MPH, the speed and trip reading are both in KM/H.
Trip is definitely mph on mine and I’ll be right disappointed if speed isn’t mph as well!

Re: Help with TSDZ2 programming

Do you configure the ST-link programme with STM8S105x6? And when you do does the little led on the USB link flash blue or red? (clutching at straws ... ) Aqua’s suggestion is worth following. With 2 of these links I have each wired for the lcd and the other the motor. I was lucky, both worked.

1, 2 and 3 are all due to the same problem: the gap between the speed sensor and the wheel magnet is too close.

Re: Help with TSDZ2 programming

RST should not be connected when flashing the motor and only connect Vcc (brown wire) if your bike’s battery is disconnected. Thus at most 3 wires to connect. Very frustrating this job if you don’t do this sort of thing day in, day out. Just slow down and take care!

Re: New "TSDZ2 Torque Sensor Central Motor"

I’ve used a grinding stone attached to my drill and gently ground away whatever is blocking you getting the shaft through. Use a stone that is the biggest diameter you can find.

Some BB’s can be quite severely distorted and still work perfectly.

If somebody has recently bought a motor from PSW Power, would (s)he confirm that it is one of the new series?

Yes, thank you. I thought it might be a warning of something but having discovered that, it’s not displaying at all when disabled.
