yeah, I guess I have that desire to know how it works & I love the challenge of making it work & DIYing...but it is true I often take for granted that I share this with most others...which I find is false more often than not.

BTW, I did do the 30A run from Rosemary Bch west (about 10 miles there & 10 miles back - with a 50mph headwind...lol)....extremely light traffic motorized & non-motorized...and could have ridden from the house at PCB if we'd wanted (we originally thought we were going farther away to start). It was actually my first real outing trying out the fixed gear conversion I built from my old Peugeot....so I can honestly say I pedaled the whole way. I figured very-flat FL terrain would be a good place to get some easy miles in on the new bike, so I rushed to finish it up before leaving town (and brought my road bike too, just in case)...with two adults, a dog & 3 bikes packed in, we either looked like serious bike enthusiasts or a circus show family on vacation!

thanks all. Hope to be back soon & on two wheels!
