Frey CC Range Primary State Variables
Because of the rainy frost warning local weather, my CC maiden voyage was down in the basement underground parking concrete bunker where I live. Since this was my first electric bicycle I did several loops around just to get a feel for the machine as a normal human powered only machine. For reference, my only recent adult experience with bicycles was when I acquired a FAT bicycle a couple of years ago as a change of pace alternative to an elliptical for low joint impact aerobic exercise. To my surprise, the Frey was much easier to pedal than my lighter KHS FAT bike. Clearly one of the main drivers is the difference between tire rolling resistance.
40 lb Fat 4 inch wide at 16 psi vs 73 lb CC 2.4 inch wide at 45 psi
Curiosity aroused of course I Googled “range vs tire pressure,” and immediately found this thread on this very forum:

The thread also brings up the significant effect aerodynamic drag has even for the relatively low speed range of 5 to 20 mph. On my electric motorcycle, range anxiety is significantly increased if I have to take the freeway to get where I need to go.
It would be good to reproduce the range vs tire pressure curves specifically for the CC (there might be some different tire options to account for though) with both average speed and test temperature as parameters to assure apples to apples comparative results.
All in all, a very favorable first impression, although if I'd have known at the time of ordering I could have customized the color and had a selection of grips, I would have done so.
