The BBSHD is a 1000W mid-drive after-market electric motor. A BlingRing is a CNC cut front gear that corrects most off-set in the chain line. I don't know other ebikes much, everything has its own idiosyncrasies, advantages, and disadvantages. But most every produced ebike has a proprietary motor, electrical-system, and battery... always too small for me. I didn't even consider trying to go low-rent on my build and I don't suggest others do either. The motor, charger, battery, and control I suggest are all better than anything I have seen on production bikes and can be changed, reconfigured, removed totally and upgraded at any time you choose. I have also heard horror stories from ebike owners trying to get something electrical repaired When it fails.
So, yes... buy the bike, buy the necessary equipment to turn it into an ebike. The few thousand more that I am taking about is for items like a 14 speed internal geared Rohloff Speed-hub, a front dynamo hub for charging USB items and running your lights, the perfect seat for you, items that stand about most everything on the market.
