Howdy again, I'm the type of rider that wants to participate fully in the ride and, as I mentioned in a previous post and as pretor pointed out, there in no user participation above about 20mph without spinning like a madman (and I have the larger front chain ring). So I swapped out the freewheel from the standard 14-28 tooth to a DnP 11-28 tooth (like KevCentral did). MAN what a difference. Now in PAS1 I'm in 3rd gear at 10-12 mph, PAS2 in 4-5 gear at 15-16 mph, PAS3 in gear 6 at 20-22 mph, PAS4 in gear 7 at 24-26, and PAS5 in gear 7 (pedaling like a madman) at 28 mph and can feel the limiter kick in. all of this (exept PAS5) is with my normal cadence of about 1 pedal revolution per second.
Of course everyone's bike will go this fast, I didn't change the speed of each PAS mode, I just didn't want to run out of gears too early. This is a huge deal for me. now I can actively participate in my ride up to 24mph and I'm shifting gears again. this was more the experience I was after with an electric bike.
The gearing on the new freewheel is such that gears 1 and 2 are the same, but after that each gear is 1, 2, or 3 teeth lower (less teeth=higher gear). losing a tooth on the rear ring has way more effect than gaining a tooth on the front ring.
anyway, different people have different expectations for how they plan to use their bikes. this worked for me.
PS. for the techno geeks out there, the standard freewheel goes 14 16 18 20 22 24 28 tooth, the DnP goes 11 13 15 18 21 24 28 tooth. 28 tooth is gear 1, 11 is gear 7.
