Sorry, fumble fingered above... What I was trying to say was, looking at the specs it looks like this hub starts at a higher gear. That would also explain for the lighter weight given that the lower gear cogs are bigger. So to me this sounds like a good e-bike hub because who really needs the added range of granny gears?
In fact, SRAM released eMTB specific EX1 drivetrain with only 8 speeds but it does have higher gear range for mountain biking conditions.
The biggest advantage with this Nexus Inter 5 is that you can pair it with Di2 and combined with E8000 motor, it's a great system for moderately varying terrain.
