So in my quest for e-bike I am only considering the bafang 620. One company says their internal gears are metal and implies the others ( I am assuming bafang 620 motor are plastic). Is this true? I would have thought all bafang 1000w 620 motors were the same internally. This co bikes are about 2500 -3k more expensive than similar bikes.
While I am at it how come it is so hard to get accurate specs on stuff like forks shocks numerous pistons a rotor size on
 
i believe all 620s have metal gears, Bafang switched to metal a few years ago. If you have an older motor its easy and cheap to purchase a metal 3rd gear.
I know my 620 has metal gears and i did not buy from the company you described above. They are full of BS imho.

I've opened my M620 twice since last year. All metal gears.
