Bafang M820 - Dual chainring possible?

[ElEsido]

Hi all

Looking at the lightcarbon e-road bike frames and there is a Bafag and a Fazua motor version. Wondering if the Bafang M820 can be equipped with two chain rings. The Fazua can, but it's limited to 25km/h whereas the Bafang is available in a version up to 28mph/45kmh.

Bafang have a video on their website that shows a road bike with a 2x setup, but I could not find any detailed information parts, compatibility, etc. Does anybody have any experience to share?

Thanks!
