I thought I might be clever and try out a Bafang press-fit adapter (https://www.empoweredcycles.com/collect ... -for-bbshd
) to fit a TSDZ2 to a pf92 bike. After looking at the axle width of the Tongsheng (end of the manual https://opensourceebikefirmware.bitbuck ... MANUAL.pdf
) it seems like the motor axle won't be long enough. Dang, any hope of redemption?
