Went for a 20 mile ride today following Murrieta creek and took a pic about every 1/2 mile
This nice walking/bike trail leads to the beginning of my ride
48v 14ah battery - I got 2 batteries
I usually run my first batter until the last bar starts blinking Then I know it's time to plan my route home with my 2nd battery
I always charge my batteries to 100%
Distance depends on a few things, maybe this will best explain it for you
