    Sounds like torque sensor not being able to sense anything because of pedal kickback https://youtu.be/XGxYZ9Rh2t4. It occurs more on certain rear suspension designs and especially evident on slow speeds with high suspension compressions (pedalling very hard/going through ditch/going over...

    Reversed them and now everything works! Strange that those would be reversed in the display cable. Anyways, now on to installing all of it on the bike :)

    I encountered error message "Error Brakes" on the first boot. I searched the forums and found casainho's post earlier this year indicating it might also be related to TX error as well as to brakes. This leads me to think that my harness wiring might be wrong, but looking at it, I can't really...

    Thanks for clearing it up! Now on to installing a temperature sensor and thermal pads before rigging everything up to the bike, going to be exciting weekend :)

    I finally got the parts delivered for flashing the display and motor controller after a 2 month wait! I flashed both successfully, but would like a confirmation about the motor vs battery voltage before plugging the battery in. Is it so that the OSF automatically can run with different voltage...

    New "TSDZ2 Torque Sensor Central Motor"

    I just got 36v motor from PSWpower via their Aliexpress site (bought on 10th, got it on 20th of April) and it didn't have any 2020 sticker. It also has the three streaks on the side cover like in the "old" motor version in the linked image. I don't have flashing tools yet so I haven't tried the...

    I'm not expert in this area so I don't really know whether this would work, but you mentioned earlier that you have a bike trainer and you can put a constant load on the motor, so I think if you can extract the torque, battery voltage and current draw at different motor speeds, you could get a...

    I want to understand the efficiency trade-offs between 36V and 48V motor. I was trying to wrap my head around this subject and researched a bit so below are all my calculations, please let me know if something is incorrect! Is it so that both motors have 4000 rpm unloaded motor speed or is it...

    New "TSDZ2 Torque Sensor Central Motor"

    That sound great! I guess you're running it on 52V battery? Do you have 48V or 36V version of the motor? I wonder if 36V version will have much higher heat generation than 48V version when running it with 52V battery.

    New "TSDZ2 Torque Sensor Central Motor"

    Seems I'm getting the motor at a perfect time! Really excited and can't wait to get all the components delivered and start testing the open source firmware. Thanks for the development Casainho and others involved!

    I ordered a 36V version of the motor and plan on running it with 52V battery in high cadence mode, so I guess installing a temperature sensor is very much recommended. Does anyone have experience/information on whether LM35A or LM35C sensors also work with the OSF? I live in a place where we get...
