It's torque-sensing and somehow "learns" the way you ride - still not sure if I detect this - so it's much more of a cycling experience than the high-power cadence systems I've used. You push the pedals and the more effort you put in, the more virtual tailwind you receive.
Its one massive (literally) drawback is putting all that weight including battery in the wheel. I haven't attempted a road side flat repair yet and don't look forward to it, the super awesome benefit of mid-drive kits is you get to keep your normal lightweight wheels. If you buy one of these things I highly recommend using one of those Schwalbes with all the fancy shmancy puncture protection.
