Re: New "TSDZ2 Torque Sensor Central Motor"

Regarding the sprag clutch...I know someone who has done it with a hammer but you can easily cause damage. My brother is a motor mechanic and he has a hydraulic press, it's just a car Jack mounted in a steel frame. We used a piece of steel tubing and pressed it out slowly. It was easy to do but if y...

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

Hi jbalat The temperature sensor should work, because it is managed directly by the casainho firmware, of course is not showed on VLCD6 display. :) :) :) Cool !! Hey I saw a picture of a fan inside the motor housing. What if we we could also initiate the fan above 75 degrees so that the motor start...

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

Hi Marco, I think some users would be willing to try your version because they don't need to change the display. However if there were some app to change the settings then that would make it more user friendly. I think the 2 versions can co-exist since some people want to see the data on the screen ...

Marco if your project is compatible with the stock displays then you have saved everyone lots of effort maybe you can make another fork on the smart ebike github and send us a link :bigthumb:

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

Im assuming these changes would work well for a 48V motor with a 52V battery? Why don't you test it and let us know ? It turns out the hailong 48V 10AH battery I bought to save a few $$(and grams) is a POS. After 10 or so rides the BMS shuts off at 43V and closer inspection shows that one of the pa...

Hi gurus,

I'm doing an install on my friends bike tomorrow and I would love to not have to flash it twice

Appreciate your help

Re: New "TSDZ2 Torque Sensor Central Motor"

I found mine was very loose when I pulled my motor apart a long time ago, it’s fairly noisy now. I think they are just common skateboard bearings if I am not mistaken, they sell some good quality ceramic bearings at some of the better skateboard shops.

Re: New "TSDZ2 Torque Sensor Central Motor"

...With that the weight of your bike is about 19-21 kg. Motor weight tsdz2 about 4 kg with rods. The GA 10S3P battery weighs 50 * 30 grams + wiring + screen + and BMS = ~ 2 kg. It turns out that your bike weighs 17.5 -4 -2 = 11.5 kg. Good two suspension! Carbon owners envy :) Dude you could be righ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Exactly Andy.. I like 14s but 14s2p is not enough and 14s3p would be way too heavy unless there are some better cells out there than the GA's ? 15s2p is tempting but will it blow the display ? And can you get a 15s bms to suit ? It really depends if you want a heavy commuter or playful jump bike.. I...

Re: New "TSDZ2 Torque Sensor Central Motor"

My reason for buying a 36v with 36v battery was to minimise weight. My dual suspension bike is only 17.5kg, my Trek Powerfly is more like 25kg and you can feel the difference. If you are running stock then the 48v motor has more power, my friend always rides in level 2 and to keep up I had to ride i...

Nah looks fine to me.. hmmm, other issues people have had is markings on their stlink was not the same as default but then you would get different errors, also not enough power on the USB port, maybe try another laptop ?

Re: New "TSDZ2 Torque Sensor Central Motor"

If I'm going to get into the game of flashing firmwares, I guess I "should" do the "upgrade" to 52v (from 48v current). I'm currently building my own battery and it is incomplete, so the only loss I would take would be the price of a couple 13s BMS modules I already purchased. Is there any NEGATIVE...

Re: New "TSDZ2 Torque Sensor Central Motor"

I have a dual suspension bike, you may check out one of my videos from signature below. I dont use the side plate or the rear mount to secure the motor. I use a plastic washer under the big nut (I got this from my BB when I removed it), this helps to stop it from coming undone. I also use some rubbe...

it says 20A continuous so should be able to get 16A @ 42v = 672W max up the 16A to 18 to get more short click and imediate long click of the top button when viewing the voltage to toggle to Amps Not sure of my exact settings but something like 0.7, 1, 1.5, 2, 2.5 but I always ride on level 2 or 3 se...

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

If I was 'truly' at 350w human power and had assist multiplier at 2, why am I not seeing motor power at something like 600W (which is what I have it limited at) instead of the 300-400w (motor power) im seeing So double check your stats. Power = volts * amps So when you were expecting 600w what was ...

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

Power on top right is motor power Amps x Volts Power in odd field when you cycle through with on/off button is human power Set to 5 levels Level 1 should be like 0.3 Level 2 can be 0.5 Etc. A value of 1 is pretty powerful, it means if I put in 200w the motor will also give 200w So use it for level 4...

the watts that you see on the display are the sum of both efforts. Not true, on the bottom it shows human watts and top right it shows motor watts. It does not add the human watt hours but yeh it could be cool to see in the future :) As for walk mode on/off we already concluded it was too dangerous...

Hey Adam what’s with the extra cover over the motor ? I liked the exposed motor better but just my opinion.
