E-rickshaw / utility cart axles from China

Does anyone have any experience with the e-rickshaw axles that come from Aliexpress? I have a small petrol powered utility cart that has a very unreliable briggs & Stratton petrol on it, 5hp (which is overkill really) that would be much safer and easier to use if it was electric. I think one of thes...

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

I've updated the release, now there's a bunch of binaries for different motor versions. Also I've fixed the crawling bug and made the current ramp even more aggressive to make more oomph . https://github.com/r0mko/TSDZ2-Smart-EBike/releases/tag/v0.56-experimental I will flash the new 36v-HC code an...

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)

Just made my experimental firmware for TSDZ2 v0.56 (0.6.10/0.7.0 850C FW). Everything works fine so far. Made a round trip to a grocery store (5 km in total). Acceleration from stand-still became much faster, but the current ramp feature obviously limits stress to the blue gear and chain, which I f...

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

It is perfect code and power delivery for my single speed setup. Please share your config (battery voltage and motor version), so I bake a personalised firmware for your setup. I'm a bit concerned that the motor setting in the menu has no influence on max RPM, so this makes me think that important ...

Re: Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

No, and the device appears OK in device manager as an stlink. It is not a big issue, I am out running the 'other' code at the moment with the sw102 and that behaves just like 0.20beta in pure torque mode.

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

I'm out riding it now, this firmware is awesome aside from some creep without pedal pressure if you set the current ramp too high. At least with my uncalibrated torque sensor. I've forgot to mention: I have calibrated the torque sensor. The creep issue is fixable. If RPM < 10, we just disable assis...

I suppose it is possible I have broken my programming cable since I used it a few days ago to program from Linux? I will try and re-flash with 0.56 from Linux and see if that goes through OK.

Re: Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

Do I need to do anything special to flash down from the latest Casainho code to 0.20beta? I have setup up my Windows machine with stvp, sdcc and the jre and have the configurator working but it refuses to flash the option byte. I know the programmer works, I used it the other day from Linux to flash...

Latest Casainho code only supports Power mode then? Yes I believe so. I am still using the LCD3, I have a 850c in the drawer because I rely on EMTB mode which is like a progressive torque mode. It is great and I believe solves all of the issues you are raising. .20beta1 is very stable. It has a few...

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

At lower RPM the pedal power is low, so the motor does not help me to gain speed, and at higher cadence it is already high to maintain speed I may not be understanding correctly but this does not make sense as the average pedal power should be similar over the full cadence range (10 RPM to 90 RPM)....

I have been over in the 'other' thread for a while having fitted an SW102 to my bike, anyway I am not enjoying the assistance that is provided by that firmware fork on my single speed bike and want to go back to the VLCD6 using the Marcoq fork.

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

I would deeply appreciate a special TSDZ2 firmware version torque-only PAS mode. Using the pedal power for motor current calculation with a high-cadence mod (36V motor with 48V battery) leads to very uneven assistance: you got no torque at low cadence and startup, but at higher RPM the motor gets m...

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?

You need to install latest version and calibrate your torque sensor. Installed, now I will try to find some weights to use for calibration. Still seeing a few lockups of the display when navigating the menus. And related to my lack of speed when using the 36v high cadence mode (see my post ages ago...

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

Any plans to implement an eMTB mode where it automatically steps up through the assist levels depending on torque input? Are you using the latest firmware version? If not, first try it and then give feedback. Not yet, I am going to try and flash up from 0.55 and 0.6.7 (I think that's what I'm runni...
