This thread is about electrifying my Giant Glory, Full Suspension, Down-Hill bike as a 2nd e-bike project.

## Existing 1st E-bike : 11k+ km, with in 2 years of conversion.
My BBSHD + DIY 14S5P LG18650MJ1 on 27.5” Bianchi hard-tail MTB. Avg 8.xx wh/km with medium peddling over thousands of km. Bike weights around 35 kgs. E-part has been very reliable while the bike's M-part has been "fragile". I have replaced 1 Shimano cassette, 1 rear hub, spokes, 1 front rim, 3 chains, 6 tires+8 tubes, 3-4 brake pads, 2-3 disc rotors, etc. Even my riding is rather gentle and 99% on concrete/asphalt road, mechanical parts broke down like crazy. I do not use cheap important parts since I am too lazy to walk the bike back home but a lot of mechanical parts managed to fail. People said it was because I mis-used them while I understand that the parts are not built to last (at all).
With 2 times re-lubing the interior of BBSHD with MobilGrease 28, still in good shape. Happy with the e-part, BBHSD is reliable and well built. With this kind of ride and periodic service, it will last easily over 10+years and 50k kms. For bike, that is a lot.
Now, I am ready for the 2nd e-bike : Downhill Full Suspension Giant Glory 2013 I bought 2nd handed. Hoping that better parts should last longer.

I do not have much experience with hub motors but feel like to get more acquaintance with it.
So, rear hub is where to begin
