I think it is better to have a removable battery. What happens when the battery eventually dies?

This concept is a joke with my grass...I'd rather soup up a 48V mower with some nice Samsung lithium. Ah, the misperceptions of youth.

I agree with you on the 5% improvement - and I suspect a lot of that would be due to going slower on average, over the course of the trip. If I'm freewheeling down a big hill and I'm at 30mph at...

I think with regen you are using your brakes more often when normally you wouldn't be using them at all! I don't see how that translates into reduced brake wear, unless you like to have average...

Almost - but only if both scenarios have exactly the same average speed over the course...hard to test this as that test condition is hard to set, given the regen drag. Need to offset regen slowdowns...

velomoover is correct. Normally the controller will have a separate 3wire connector just for the PAS, and another 3 wire connector for the throttle. They are not spliced together.

Oops...I've built a bob trailer with a Crystalyte 404 16" hub, but I've got too many 20" folders with conversions. Losing my marbles.

I had a similar shimmy on my Actionbent T1 trike set to the correct toe-in. I cured the problem for the last 1000miles by leaving a greased o-ring around the fork steerers, just under the headset...

It will be no comparison between Lead-Acid and LiFP04. Lead acid suffers from the "Peukert effect", and voltage drops very rapidly across the discharge. The lithium has a very flat discharge curve...
