Used to commute 30 miles a day round trip, about 3 days a week average. Now it's more like 11 miles round trip to the grocery about 2 days a week. Less if I take a car someplace far, when I usually hit the store on the way home. I'll often make that grocery trip longer, taking a long way route to the store just because it's a beautiful day.
Sometimes I'll take long rides, my personal best being 80 miles in one day, and about 200 miles in a three day trip. I've also "cheated" and taken a car to a nice place to ride the ebike a lot. Bit by bit, I rode almost all the way across the state, from El Paso Tx to Santa Fe NM. Those tend to be about 60 mile rides, park, ride out 30 miles, back 30 miles.
I ride off road a lot too, and because of the way the bike will handle with more than 15 pounds of battery, those rides tend to be about 8-10 miles max, per outing. At least a weekly ride that long, and many many short 3 mile rides on a single track loop that is right at my house. No idea how much of this I do a year, but a good guess would be 15 miles a week.
