Game Changer for EMTBs?

We’ve been constantly testing the Amflow electric mountain bike over the last year or so, and Smoothshift has got to be one of the coolest features of the Avinox platform - essentially allowing you to shift while coasting. It’s a game changer when you are always riding in that smallest cog and need to quickly get into an easier gear - with the latest SRAM transmission update this could be even more useful. What do you think about this tech? Must have for an e-MTB?
