Tongsheng TSDZ3H Anyone tried?

Featured Replies

While browsing the Tongsheng website I saw the TSDZ3H and I was wondering if anyone had installed this mid drive unit.

Never even knew it existed! Got a link?

Ah gotcha. Yes have seen a Bafang in the same style. Prob a good option for replacing a Bosch or Shimano setup that may be beyond economical repair?

I doubt if one can simply swap out in to any other frame as the housing will be different. Unlike a BB crankk drive which uses a std English type in the main.

Pretty sure none of the various OEM bespoke housings are compatible.

Yes agreed, and I understand that, I was just wondering if the TDSZ2 & TDSZ3H shared the same mechanical & firmware structures, aside from the form factor. For example did the OEM TDSZ3H use the same "Blue gear" or did it have some improved version to satisfy the OEM customers more demanding quality needs. Feedback from the brands using the OEM version may assist us lowly DIY builders in future improvements or upgrades.

Internal design will be chalk and cheese, as is the Bafang BBS & Max drive.
