Hi All - I have just installed a TSDZ2 onto my wife's gazelle chamonix c7 - what a mission!! Anyway I won't get into details but I just had a couple of questions if anyone can help. 1. I want to put the main cable through the frame with the brake and gear cables. To do this I need to cut off the co...

That happens to you because you did not update your firmware to most recent version. Yes, on purpose. I depend on the bike daily and can’t afford it getting destroyed. I have read several reports of controllers blowing up with later versions. There is a rather ominous warning on the download page f...

My tsdz2 has behaved strangely. Sometimes gives a very good assist and sometimes very badly. I started adjusting the torque sensor. I measured its value first and it was 157. The minimum value I can adjust it to is 64 (should get to values of 25-30). Is the sensor simply broken. I have that too som...

I wish I had the skills to do it but I know nothing of C or C++

Would you consider adding a configuration option to hide the clock altogether seeing how unreliable it can be and how much it can drift if you don’t use the bike every day? I’d personally much rather not see the clock at all than seeing it display the wrong time every time. Which Version you have i...

How do you guys find the motor waterproofness? I live in an area with a lot and sometimes very heavy rain and I would still like to continue cycling in such weather. Do you think the rubber seal on the motor cover is enough to not let any water in? Did anyone try to add silicone or something else t...

I've got an 860C display and two USB-UARTs with the DIY cable all wired up correctly. I can switch on the display and see that it has power. When I boot APT Burn Tools, select port 3, open port, openFirmware, start update. The RX and TX counters start going up and waiting appears in the status wind...

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...

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...

Is v0.8.0 safe to use? On the release page it comes with this rather worrisome warning: > WARNING: due to any possible existing bug on the firmware or user incorrect configuration, the motor controller may burn and/or the motor and bicycle wheel may start to run very fast at max power - please be ve...

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 ...

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...

Hi everyone, Does everyone know the maximum operating temperature of the TSDZ2 neodymium magnets ? I'm doing some tests involving oil cooling but I don't know how hot can I go without damaging the magnets 80°C seems to be the limit for standard magnets but AH magnets can operate in temperatures up ...

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. I'm planning to use it on a gravel bike with drop bars. Looks like VLCD5 will mount there without any problems and I'm actually pret...

Anyone using navigation apps on your smartphone with the TSDZ2? I’m having issues because the motor generates a strong magnetic field that completely confuses the compass in my phone. That impacts navigation and as a result the phone is completely lost as to where I am or which direction I’m going....

Does anyone know wether there will be any problem if I have temperature sensor installed and I revert back to stock firmware? Mainly for making comparisons, I'm not planning to use stock for a long time so I wouldn't want to remove the sensor just for that. Yes there will be problems because the or...

For the last few days I’m having issues with initialization. When turning on the display, I keep the right pedal down as per the settings and wait until the startup message to go away. More often than not one of two things happen: - the torque sensor reads insane values, like barely pressing on the ...

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.

My motor did really bite into the frame at the chain stays :( I’m worried this will cause a rust issue down the line since this frame is cromoly. What do you guys think? You should put 1 or 2 layers of inner tube between the frame and the metal part pressing against it. I opened the motor and it lo...
