I totally agree that *adjustable* levels are preferred... they should actually do that for any type of rear hub drive cadence sensor system. But practically speaking, I just don't know that there is much difference/variance between 9 levels of PAS because would you be looking at 2mph/4mph/6mph/8mph/12mph/16mph/20mph/24mph/28mph or 9 percentage steps or however you would set it up and what would be the usage for certain levels?
So while 9 levels may be a sell point for many... in the end... for me, it's not... but the *adjustable* part is. And then again, if the proper percentages of the levels are done correctly... then there may not even be a need for having it to be adjustable (like 5mph/10mph/15mph/20mph/28mph).
I think if the PAS 1 is set low enough to not cause unwanted speed boosts and PAS 5 can hit the top speed, that's good enough for me.
I guess because when I rode the Pace 500, Level 1 seemed pretty powerful to me that I figured Level 5 would probably only be used for hills. At the same time, this thought went into my head... it would be much faster to get to Level 5 then to Level 9 if I needed it... 4 less clicks.
