You have to go OSF all the way. Make sure to match the display version with the right motor version of the osf

Thanks bergerandfries - going through the on/off testing as you suggest , in the meantime I have contacted PS POWER and asked for a replacement controller - which they have agreed to if I pay the shipping cost , however, I bought the system as advertised as 36v and 500W - the controllers they appea...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Sorry for that question, but I don't really understand that calibration procedure. First of all the ADC values vary from left to right side. Is this normal and what do I have to note? When do I have to switch the calibration value from disabled to enabled? Does enabled mean that I always have to ca...

I'm in absolutely the same boat. I use to flash the latest firmwares but after a couple of incidents i decided to stick to one that's more tested with time. I can confirm 0.7 works ok (https://github.com/OpenSource-EBike-firmware/Color_LCD/releases/tag/860C_850C_SW102_v0.7.0). This one is the lates...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hey Guys. I notices that a new 2020 version of tsdz2 has been launched. Have any of you guys tried reflashing it with the opensource firmware? Apparently it’s the same motor as ever, there is no new 2020 version. It was discussed in this thread a few weeks ago. Probably just sellers trying to hype ...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

I'm running v0.6.5 on my 850C but it has become unpractical because it gets too many initialization misfires (where it either reads the torque sensor wrong, provides no assist, provides way too much assist on barely touching the pedals, or makes a horrible noise as it assists.) I understand this has...

Hello, after extensive research and lots of reading about BBS02 and TSDZ2 yesterday I finally pulled the trigger and ordered TSDZ2 36V 350W VLCD5 LCD from Aliexpress.

Isn't it better to use some old bicycle tyre instead of inner tube?
How do you cut a tire though? I couldn’t go through the metal wires on the edge.

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Out of curiosity: can the firmware be downgraded on the 850C? Or even the original firmware put back? This is of interest in case a current release has a major bug. I and probably others rely on their bikes to be fully functional at all times to run errands, go to work, etc. Without the possibility ...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

The only bugs: at assistance level 15 or higher you can make the motor go to full assistance just by moving the cranks very slowly, which is kind of cool and fun, like a foot throttle. I tend to ride on level 13 all the time, I found that gave the best assistance for my cadence and still gave me a ...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

The usability of having to calibrate the torque sensor each ride would be too much for her. She expects the bike to operate just like a car. Turn it on and go. Seems you didn't understand. Torque sensor calibration is only done once. Great. I thought the crank arm had to be positioned correctly eac...

I'm a bit confused by the sensor calibration procedure. How many different weights do I need to find/use? And do I need to do each side, left and right? Ideally 7 or 8. You want to go the whole range between 0 kg and however much your sensor tops up at. That will give you more points for the curve ...
