Re: New "TSDZ2 Torque Sensor Central Motor"

Think about Shimano alfine. Our chainline is pretty good with the stock offset chainring, however my largest cog is only a 34. Hopefully we won't have issues when we upgrade to 11-40 wide ratio. My chainline lines up between 4th and 5th gear on our 8 spd, I would say very close to 5th gear. I assum...

Re: New "TSDZ2 Torque Sensor Central Motor"

However here is a 10mm offset chainring that will bolt right to the stock adapter it's not cheap but neither was my time figuring out how to do my hill billy version and that ring alone was $80 retail. http://www.electrifybike.com/store/p65/42_Tooth_Narrow%2FWide_CNC_7075_T6_Chainring_%2810mm_offse...

Re: New "TSDZ2 Torque Sensor Central Motor"

TS had sold me some 'stock' 52v 4500rpm units, but that was only the first batch, then it was back to 52v.... Where are these bad 52v units coming from? I bought mine from https://www.dhgate.com/product/new-version-52v-750w-tongsheng-tsdz2-ebike/407467694.html seems to be storefront for auto_ebike....

Varicore Batteries

I am looking for plain jane battery packs for an inconspicuous 36V low-power setup (350W). Varicore has an Aliexpress store https://varicore.aliexpress.com/store/1672014 In it they have an interesting 10s3p pack with internal BMS https://www.aliexpress.com/store/product/VariCore-36V-7-8ah-10S3P-High...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi, I know some people have had problems with '52v' units not actually being 52v etc... I drafted up a little programming manual for someone, maybe more people can get some use from it. It goes from making the programming cable, to installing and configuring the software (for windows) to the actual...

Re: New "TSDZ2 Torque Sensor Central Motor"

There has been several complaints already, as the TSDZ2 offers both, a huge Q- factor and the crankarms not centered to the middle of the bike frame. A single crankarm is only $10. Ah ok, and the bafang is the only crankarm that will fit this? Just asking as they're not readily available in my coun...

Re: New "TSDZ2 Torque Sensor Central Motor"

Would a TDSZ2 topic in the technical reference section work work for condensed and organized information? You got me, maybe one of the site admins can make suggestions. I think it would be great to have something like that, especially if it were a locked thread where only reference info and no comm...

Re: New "TSDZ2 Torque Sensor Central Motor"

New people to the thread - lol :) I'm glad we joined in when we did, I think there was only 65 pages or so back then and it was a real chore to read through it all. If I had to start over again I think I would rather walk! I think the cat is already out of the bag though. Perhaps eventually someone...

Re: New "TSDZ2 Torque Sensor Central Motor"

TomTom, it really all depends on when the back of the gear reduction housing hits the chain stay. I have put on quite a few TSD's and you lucked out getting a 51mm chainline on your first try. I had to fit another 42t chain ring on mine because although I didn't measure it the chainline in my 42t i...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi, I just did the install and it works. I agree about keeping the open source firmware on the dedicated thread Endless Sphere thread: "TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor" I find the open firmware development intriguing, but is there any way the discu...
