Cracked it! It is the Option Byte that needs to be changed back as well. After a lot of messing around swapping between the OEM setup and the Opensource I discovered that the open source firmware changes a couple of lines in the Option Byte even if you only select programme current tab. Nice work! ...

HI! I have the coaster version of the Tongsheng TSDZ2 and gets a kick from the cranks when releasing torque too fast. It seems that this is because the controller/firmware is for the non-coaster version. Right? What to do? Can I flash the controller to the "coaster-version-firmware" or can I solve ...

- Walk assist enabled without having to hold the DOWN button (maybe not a good idea). Disables immediately if user presses ANY button. - Cruise function enabled without having to hold the DOWN button (maybe not a good idea). Disables immediately if user presses ANY button. - Cruise function with mo...

This will be a big one…

Great stuff buba!! I can't wait to try it. Thanks!!

Nuvinci stepless IGH are perfect for mid-drives like the TSDZ2. Keep an eye out for the new N380x It is rated for 500W but early literature said it was designed for bursts of 1000W which puts it up in the BBSHD category. Fallbrook Tech went bankrupt in 2017 but rebranded as Enviolo. The N380x is fou...

The VLCD5 has a setup screen for amps. It doesn't actually do anything. People have wasted more time screwing around with it and trying to feel a difference. Shame on TongSheng. I assume the VLCD6 is the same. If you get it in the Power Select mode I doubt it actually does anything. No, it work .. ...

Some motors are louder than others. The open source firmware in my experience is nominally quieter and more efficient. I wish I knew what the variable was so I could try to make mine quieter. I'm going to need a lot more than a nominal improvement to get it down to what I'd like (I'm used to a BBS0...

My first impression is holy hell it's even louder than I feared it would be after reading this thread. ... My second impression is that it feels a little hamstrung on the steepest hills (15% - 20% grade). I think the problem might be that maybe it's locked into the default 250W mode. I wasn't able ...

Here is the final design (I hope): https://i.postimg.cc/SQDvXdz0/Bafang-850-C-color-LCD-design.png - break and lights symbol (not show on the image) should appear at top, in the middle - the four fields at the middle can be customized: the data to be shown at each filed can be one of the many varia...

Thancks marcoq for your contribution ... Firmware tested with VLCD5 and seem to work fine . ... Thank you elem for your contribution! :D This is awesome news. It means existing TSDZ2 conversions can be upgraded by just unplugging the Speedo sensor and flashing the controller. The LCD3 and 850C disp...

Rod going through the swingarm without interference through the whole stroke. I might have to double up the brackets to prevent flex. https://uploads.tapatalk-cdn.com/20181230/98379be8ccb47f06adbbae053529953d.jpg Guys this is so over the top engineering, that would support the torque of V8 engine l...

It s good to find this work
as i don t need all information, i ll try first this code with a VLCD5 asap .

Very interested in testing with VLCD5. Please let us know how it goes.

The LCD model research phase already ended for me -- I had in consideration opinion of others, like professionals that had being selling ebikes with Bafang motors. Since unfortunately I am being almost alone in development, I guess we will stick with the 850C model. If there were other developers h...

endlesscadence has asked me to write down some kind of "how to go about it". He meant to go over it and post it on the wiki, but i am afraid he is no longer active. at least i have not see him post here for 2 weeks or so. So therefore i am attaching what i have so far, there may be some mistakes in...

If you'd like the VLCD6 to display mph, simply take the circumference values listed in the manual and multiply them by 0.62. If you want to set the speed limit to 45km/h hold down the power and + button for 10 seconds. Clever idea to get mph mossboss! I can't believe I didn't think of that! Has the...

The biggest difference was power. When I switched from a VLCD-5 to a VLCD-6 on one of my bikes ( 48V, 750watt ) power was limited to 300w and speed was limited to 25kph . Changing the data memory ( as outlined by Eyebyesicle ) had no effect. Changing to the 52v ( "stock" ) firmware ( as supplied by...

i happened to stumble over this...maybe of help?: https://www.ebay.de/itm/Ebike-Stabiliser-Bar-For-Full-Suspension-Bikes/323554114215?hash=item4b5553faa7:g:Rz4AAOSwWz5cBPiD https://www.ebay.de/itm/Ebike-Stabiliser-Bar/223234132480?hash=item33f9ca8a00:g:pMcAAOSwkFZb72Fb it is for bafang, but it will...

In the spirit of "keep it simple ... ", I think 3 buttons is perfect. I wrote this earlier: "Regarding needing more buttons. I have used both and find 3 buttons is fine. You can do everything just as easily with 3 buttons using long and short presses of the 3. Long press on + button is headlight and...

Hello, I installed my TSDZ2 to my bike today (https://archive.trekbikes.com/us/en/2015/Trek/7_2_fx#/us/en/2015/Trek/7_2_fx/details). Everything went well except that I was only able to secure the motor using the plate that attaches to the bottom bracket. The motor comes with that additional plate t...

Just think about a short press for light und a short press for walk assist. There are more possible 2-Button Combinations. Offroad mode could be even a little stealthier. And a good way to overcome your 200 Clicks "change the battery"-setup (One Key as digit modifier during the setup). This would b...

So, the Bafang 850C color LCD is being working very well, very stable. I found that on main screen I am using letters that are too small for information like battery voltage and battery SOC in percentage... I plan to do the main screen again and this time using bigger letters and bigger symbols lik...

DIY EX1 to adjust chainline I've been using a Sunrace 11-42 10 speed cassette with the standard 42t chainring supplied with the TSDZ2. Chainline in first gear is not great but it works. However, the gearing is still too high for serious MTB use or towing a trailer offroad (I do a lot of wild campin...

Just a question, I currently have a 36V TSDZ2 with custom firmware up and running great for Two years now. I'm planning to make a second ebike with the same motor, but should i go with 36V or 48V motor… to put it simple (from my understanding, of course): the drawback of 48V is that your battery wi...

Option 4. I have used then all except Luna. When viewed at home on a computer screen 4 looks the worst but on a moving bike it is the one that is easiest to see and quickly digest the information. That model comes with both a digital which is the mode shown or an analogue graphical display (same as...
