I do like the throttle on my mid drive, as it still allows me to top up full power on demand regardless of my gear or PAS level. It is nice to plod along in PAS 2 or 3 for good range, but be able to add full 'boost' for a quick pass, acceleration in city traffic, or steep hill. I don't use my throttle outside of that and rely on the torque sensor for most riding.
And as for Stefan's comment about fat tire bike not being the 'best way to go', I don't think you can make that comment unless you live here and experience things from our perspective. We also drive far more pickup trucks and SUV's, drag giant travel trailers around, and drive all manner of ATV and off road vehicle too. Canada and the US are very big spaces with much more rural and undeveloped areas, we require more expense and effort in our transportation sectors, and utility equipment is the norm for many of us. Cargo bikes are massively popular here, and they truly are better with fat tires when you are sticking 2 or 3 three kids (or a passenger) on the back with no suspension. Road networks are expensive to maintain, so rural and even the edges of suburban areas can be very rough and wildly varied, so it makes sense for many of us. For the city-only commuters in our dozen or so metropolitan cities (and yes, that's all we have in this gigantic country), it probably isn't the best option, but style does come into it as well. Skinny road biased tires are simply not effective for 98% of our undeveloped country.
