The HUB Motor – this HUB motor were sent to me in 2016 but start working on it about a year later (2017), hard to find one suit my need, this is the closest one can find on the market at the moment.  I should have consider building one.

Disassembly – hmm, one way clutch, draggy design (no good)… could be better

Checkkng every detail…
