NuVinci 380 rear hub which is great - you can change gears anytime, load or no load.
MPF Drive 6.0 motor which has been changed under warranty once, works ok but I don't think it would be reliable if I was doing courrier work at 50 miles per day instead of 50 miles per I currently do.

NuVinci 380 rear hub which is garbage
Sorry had to ftfy.
I rode a butchers and bicycles for work for a while with nuvinci, and there is so much lost energy in the rear hub. If i locked the brakes and stepped on the pedal, you could see the cog spin a rediculous amount while the hub was completely still. Some flexy stuff in there. When the motor died you could really feel the flex, almost lagging, sort of like riding an oval ring for the first time. And the shifting is shit when the pedals are getting pushed. Shifting while pedals are not in motion is definitely best.
