Probably I'm describing it badly, and maybe you can adjust your BBS to do everything the Bosch was able to accomplish, but for me I was able to go around a very tight uphill switchback (where I stopped pedaling to inch my way around) or "crag" in the trail (where I had to stop pedaling so the cranks would clear) and still initiate pedaling again with the Bosch where I don't seem to be able to that with the BBS. I attributed this to the torque sensor. This is a seat of the pants, not done at the same time on the same day evaluation (but on the same trail and "crag"), so could be a load of the stuff that makes grass green. Also, for the three or four weeks that I had the Haibike, I didn't ride anything else.
