The bearing is 9602RS and can be found in many shops, I bought mine from here.

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Any possibility to get Tomcys' info added to the home made bootloader Wiki? His info would have sped me on my way to discovering my swap of Tx/Rx Look that my USB<->UART don´t have any LED so that would bring confusion to make a such detailed information of something the user may not have.

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Hi, I received a 850c from pswpower and am trying to flash it. I noticed it doesnt fit into my 4-1 cable because it came with a female end so i attempted to put on a new male connector (luckily had a spare). Cut it up and see that the colors are off and the pin positions dont match with what tsdz2 ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I've got a 850C and 52v stock firmware setup that I want to move to the Open Source firmware for both. However, should I go with 850C Version 0.6.2 (which pairs with Motor Version 0.51.0) or wait for an impending release? I guess what I'm asking is what is coming soon from the developers versus 0.6....

Casainho you write "860C/850C has a specific hardware to keep counting time even when it is disabled or when you remove the ebike battery. ".

Please input on use of Gear Sensor? What is your opinion on using the Gear Sensor with the TSDZ2?  I have one installed and I find that when I climb hills, and shift, the motor cuts off, and then takes a bit of time to ramp back up again giving me assist. Kind of 'jerky' but I'm under the belief th...

Re: New "TSDZ2 Torque Sensor Central Motor"

Can someone point to documentation that the TSDZ2 only works with 52v batteries with Open Source Firmware? I'm pretty sure that's the case, but wonder if someone figured out how to set the 54.6v max to 58.8v without going to OSF? I ask because I bought the Euronau 48v TSDZ2 kit with the 850C displa...

Re: Tsdz2 firmware open source adapted to vlcd5

Your motor might not work at all until you flash it with new firmware, as most of them will only start with a 48v battery. Default software on most will only startup the motor when battery voltage is below 55volts. 52v battery charges to 58.8volts. You can not change the power limit on the default ...

No, that won't be the ultimate test. That test is putting a few thousand or more miles on the frame. I go through steel Bianchi frames regularly.

Re: New "TSDZ2 Torque Sensor Central Motor"

So the motor can overcook even if it's not hot on touch? It probably is hot to the touch, but "how hot" isn't a good gauge if you are cooking your motor or not. The only gauge that can do that is a gauge directly mounted to the metal on the inside motor, thus why so many folks like the opensource m...

You might want to see if your charger has any internal voltage adjustments. It might be something as simple as a single potentiometer for that. If you find one, you can first mark it's original position (take a pic, etc), and measure the output while altering it. If it does not do what you want, pu...
