I am running stock 52v firmware on the motor and euronau firmware on the 850c, and it also does the same. I usually turn off things by flipping off the switch on my battery, but I will start using the actual power off button on the 850c first and see if that resolves the issue
I always switch off with the display button first (this also ensures the odometer is saved if I’m not mistaken) and then switch the battery off if not at home. The clock still shows the wrong time more often than not.

I have an issue that I haven't found an answer reading here.

52v TSDZ2, system does not power on with power switch on VLCD5 display or remote handlebar switch, but if I unplug battery and reconnect it comes on without switch and runs fine, then after power off with switch it will not come back on without disconnecting and reconnecting battery.

I may have another display to try, otherwise connections seem good, battery fully charged, this bike has been running almost 2 years

Did the VLCD5 get wet? It's been my experience that the display exhibits odd behavior after getting wet...

I have a query in to the owner about moisture as I'm trying to get bike going for her, I'll post back what she says and I may just open it up anyway as we both suspect this

TSDZ2 running at 1400W, 25 Amps

I did that by mistake, running TSDZ2 at 1400W, 25 Amps, with my development firmware... I did run for only about 1 minute and here is the result on the blue gear, the one at right side (the blue gear at left side is a new one). I think that would not happen with the brass gear but anyway, the motor would heat to fast to be useful running at the 25 amps.

New firmware release, 860C display now works!!
Is it possible to install firmware on 860C using the same bootloader hardware as for the 850C or does it need different equipment?

Thank you for remembering me that I need to update the documentation :-)

Yes, it is just the same process. The only different thing is that you need to select the 860C firmware file instead.

I finished my bike today. Have the Alfine 11 installed, and a 52T front ring, 20T in the back. But this is too high geared. I will revert to the original 42T next and try that. Also have 16T, 18T and 23T for the back to try and get the optimal setup.
The IGH hubs almost always have an overdrive function the cassettes don't provide. This can work well for small wheel bikes and wide rear hubs that can run small chainrings in front.
Sheldon Brown's gear calculator has the IGH hubs in it and can let you see what you will have for gearing. You can input several chainrings and rear cogs at once if you like. The chart gets complex but it CAN do it.
https://sheldonbrown.com/gear-calc.html
I use a 16 tooth and a 23 tooth sprocket at the same time on any Alfine & Nexus hubs. Machined down and welded together with a derailleur.
It allows me to have the best of both worlds, speed on the flats and downhill and great climbing ability on the uphill. https://youtu.be/G6kQvM4Or3U https://youtu.be/PH0vLcno_Xc https://youtu.be/NP3uKfEMF_Q

Nice one. That gives you almost 50% more gear range. So you know have a spread of around 600%. But on the other hand it ruins the simplicity of the IGH setup alone, and adds a lot of complexity.
EDIT: seeing the 2nd video where you introduce the bike I'm totally stunned. What a great bike! And I see that the second shifter is only a little part of it. There's more complexity to it 8) . Very well done - especially the chin shifter ...

Need some advice. Hello. Somehow it became strange to drive a motor. Help is not. When you stop pedaling for a few seconds, the motor runs. Everything used to be perfect. Factory firmware. Motor 36/500. Torc sensor dead?

Maybe someone came across a similar behavior of the motor. Namely, he began to work as a PAS assistant. You touch the pedals and he immediately turns on all the nonsense and does not immediately stop. And when you press normally, somehow it doesn’t really help. In the output analysis, I will try to get and inspect the torque sensor. I don’t understand what happened? Thanks for any comments.

Thanks, Casainho, Today electrifybike.com is going to install the "overrun" modification on the old beta 20 to see how that works. And then later this week we're going to install an 860C and your latest software on my hand-cycle. Where excited to try your latest efforts and your support for the 860C. I'm very thankful for all you and the others have done to improve the TSDZ2 system for hand-cycles and regular riders, my wife loves her TSDZ2 with an 850C.

We tried to install an 860C today, it comes up on the screen and says waiting for tsdz2 and then it says firmware error.
We installed the 860C 69 files on the 860C and installed the 55 files on the TSDZ2.
Any suggestions on why this went wrong and would not work?

Well, then I think I have much more development work to do. I am waiting some 860C units on the mail and then I will be able to test connected to the TSDZ2, something I didn't yet...

I'm getting a firmware error on boot with 6.9 for the 850C and 55.0 hex file. Went back to previous version I was using and all is well. Anyone successfully running 850C 6.9 with the 55.0 hex file? I looked at the change log and it looked like 6.9 was associated with a 56.0 hex and then knocked back down to 55.0. At any rate not working for me.

Update: I dug into the binary and I think it is looking for a 56 hex, not a 55. Going to recompile from source tomorrow and see if that fixes it. Could be looking at the wrong thing, but what I see looks suspicious.

In a recompiled binary 10bf8 - 35h ('5') and 10bf9 - 35h ('5') or '55'
In the the downloadable 6.9 binary, those values are 35h & 36h which is a '56'

The version of motor firmware expected is defined in a Makefile. I think the online 6.9 was built with the wrong value in the Makefile.

Ok, did nothing but download your source, recompile it, and load it. It worked. No more motor init errors. I did modify the 850/860 Makefile to default to a bootloader version, but didn't touch anything else - the rev was correct in the downloaded source.

Pretty certain it is the rev in the Makefile - think you have one hanging out in your source tree somewhere that it is getting instead of the one you think or you are not pushing the bin you think you are. Just guessing at what it could be. I would MUCH rather use your compile than mine since you know the tools and I just patched them together from your guide. A big part of the reason I chose the TSDZ2 over something else was your code - great work.

I just pulled again and same '56' in the binary. The newly downloaded copy was a perfect binary match of the previous one. Maybe the old file is not being overwritten on the upload repository?

Don't know if these executables use checksums for integrity, but I could plug the '56' with a '55' in the downloaded file if it doesn't care about hacked binaries and see if that is it for sure. The bin offset is at 10bf8 and 10bf9. The '6' or 36h is at 10bf9.

Update:
Ok, I did that - hacked the downloaded binary from the online asset list replacing the 36h at 10bf9 with a 35h - basically making it look for a 55 version motor firmware vs. a 56 rev and the downloaded firmware worked fine after patching the byte.

Couple things I could think of if you are rebuilding with a 55 and it just isn't showing up in the online copy:
1) The mirror you are uploading to isn't replicating (making some of us still see 56 level software), Not sure how to solve that.
2) Just give up and put a 56 rev motor file out there even if it is the same exact thing as the 55 rev to make the display software happy.

After a bit of trying to figure it out, I would probably go with option 2 myself - I'm pragmatic, why waste time :). There is option 3 too and that is I don't know what I'm talking about :).

Hey all,
I'm new here and just a few days ago installed a tsdz2 750w and a 48v battery.
It works pretty well, but in terms of speed I'm a little disappointed, with speed limit setting 25 kph OFF, I reach 30-33 kph on flat ground, I thought top speed would be higher.
Is this all right, Is 30-33 kph as expected?

Totally depends on your bike and weight. With a fatbike and bad gearing it sounds reasonable.
What's your cadence in highest gear? Normally, I'd say 40km/h needs around 1000W, and this kit is able to deliver 500W sustained and ~700W-800W (battery) peak.

One of the wires coming from controller to the display has original battery voltage, in my case 48v. I've got dc-dc step down voltage converter with usb that I'm planning on wiring to that wire to be able to charge various things while on the move, such as phone.

Any ideas what kind of current this wire can handle?
