In my case, the battery level at the end of a ride would be meaningless.
I almost always carry a spare, and draw down each one to 50% or so. That way, I don't have to recharge before storing the batteries.
I don't disagree. I was only relaying my experience. I'm not saying max tire pressure is most efficient everywhere under all conditions. I've done a lot of testing by recording range vs tire pressure and max works best for me for where and how I ride. YMMV.
FWIW, the advertised range for my bike with 500W rear hub motor and 17.5AH battery on smooth level ground for a 150# rider using minimum PAS is 65 miles. These specs assume you charge the battery to 100% and discharge until the BMS low voltage cutoff trips, usually around 15% in my case. Many...
