Ok, I'm having another problem. Can anyone help??? I had to change out my sprag clutch because of it slipping when pedaling. But right before I changed it and now even after I changed it I'm having a new issue. I will be pedaling in either Tour or Eco mode and all of a sudden it will accelerate lik...

Hi all, I am having some issues installing my Tongsheng TSDZ2 on a Whyte Whitechapel frame. The motor fits in the bottom bracket, but the bicycle frame has a bulge that is preventing the motor from sliding through fully. Have any of you folks any tips at all? I'm hoping this is solvable :-( In you ...

I see there’s now a standard TSDZ2 available that has Bluetooth connectivity. A few Europe s sellers on eBay have it. An user told me that TSDZ2 Bluetooth version is in fact the regular TSDZ2 + VLCD7 display that has Bluetooth inside: http://www.tsbicycle.net/index.php/content/150 Since VLCD7 is no...

Hi all, I'm trying to remove my tsdz2 helical main gear, following the Jbalatutube youtube video. Unfortunately, after removing the 2 circlips and housing, I cannot get the main gear off. Am mystified. See image below. The bolts are inserted to assist pulling out the gear but no joy. Any suggestion...

Has anybody been experimenting with turn signals/blinkers? I would like to add some to my tsdz2 because I am often riding at night on steep roads with lots of traffic and I don‘t like to let go the handlebar in this situation to signal a turn. I think adding electric turn signals would be a bit of ...

Can you help to improve the wiki with this information?

Yes I will try.

I went and pasted your notes and images. If you think it can be improved, please go ahead and edit the wiki:

I have just flashed 850C_v0.4.2-bootloader.bin with home made bootloader box successfully and display turns on however the vertical screen flip is still present. Also seems that I cannot flash it anymore as the display is not reacting to flashing signals from USBUART module as before. Is there a ch...

Would please fully document your build so it could be linked from the wiki main page, on a gallery of builds with TSDZ2?? I'm new to this forum, is there a protocol for how and where to document builds? should I do it in this TSDZ2 thread? thanks! The final documentation will be placed on the wiki ...

I have a TSDZ2 mounted to an Xtracycle Edgerunner and it is nearly perfect now. Thanks to redline1for the encouragement on installing this kit on my Xtracycle Edgerunner. I took some pics of the aluminum bar adapter I used to get the battery mounted low, behind the motor. There are bolts back there...

Hello everybody, About motor temperature and cooling. I want better cooling, to be able to pull more power.. In the following I will describe my setup and use-pattern and hope to hear form anyone who have done some cooling experiments... I have had my Tsdz2 (48v.) for some months now, I run the v.1...

Any ideas? Is there a way to test the motor to figure if that is the problem? https://uploads.tapatalk-cdn.com/20191009/ef4fc80f2d13ac75d3b96cbd45fb722e.jpg Sent from my iPhone using Tapatalk Double check if one of the 2 thin wires of the torque sensor coming from the other side is broken. Long ago...

,.... The cgq8 is the speed sensor with a double head connection for lights. In that case it looks indeed only a different controller with bluetooth with the same motor. This has consequenses for installing (and developing) OSF. Please find pictures of the motor controller and also, if possible, pl...

has the startup boost funcionality been removed from 0.20? I don't see it in the 0.20 configuration manual on the wiki Buba removed that feature from 0.20.0 but I plan to implement it again on 0.21.0. In fact, I created an issue so I will not forget this: https://github.com/OpenSource-EBike-firmwar...

I asked the ebay selle abou the app: "The APP name is "My e-bike", I attach a photo" The app can be found in Apple App Store My e-bike by 苏州同盛动力科技有限公司 https://apps.apple.com/us/app/my-e-bike/id1459342730 It is nice. Good!! Maybe you can also ask if is possible to buy the new motor controller and if...

I have a similar problem with Adam. When I press walk assist the display shows 100W but the motor does not move. I also took it out. Without power I can move motor head easy. With power it is fix! Torque sensor diag works ok, also cadence and speed measurement. Just the motor does not move! I can h...

omg! I need to order one. Wonder if other suppliers have them Feature: 1, Easy installation, applicable to most normal bicycles 2, Max Torque about 80N.m, strong ramp-climbing ability 3, Internal controller + axial torque sensor (genuine two-sided torque) 4, Compact size and elegant shape, weight a...

Is the Bluetooth on the motor controller or in the LCD???

Can you share a link? I could not find it.

We are working to make SW102 the easiest display to install the firmware, by Bluetooth and without the need to ever open it (this is possible already, Geeksville developer already have this working but this need more testing). There is a catch, the original firmware uses a very old Bluetooth firmwar...

I understood that on the kunteng controller label : - rated current was the maximum current coming from the battery. It drives the maximum cruise speed. - max current was the maximum current coming out the controller. It drives the maximum acceleration especially at low speed and it also called max...

Nice so it LVC is reached then power keeps dropping to ensure LVC is not violated again ? I assume that eventually the power cannot be dropped any more and the motor will turn off ? You guys should try and see. Just adjust LVC on display to a value near your battery current voltage. Also note that ...

Perhaps I wasn't clear in my post. I am very happy with the current OSF firmware v.0.20beta and with the settings. I noted a drop in peak power when the battery starts to be around 25% (this is the first time I discharged the battery that much during a trip) and I read in the wiki this limit is som...
