Sorry I was editing while you quoted me.Have you owned other e-bikes? If so which one?
I worked part time at a bike shop up until last year and have owned the Cannondale Habit Neo 2 with a Bosch drive system. I bought the Habit Neo without demoing and found it to be quite large for me and never warmed up to the bike
As for the drive systems:
I liked the power of the Bosch and there are times that I miss it, but I've never loved climbing so the flowy cross country type trails I really enjoy are fine with Fazua.
The overall nimbleness and Fazua assist suits me well.
