Welcome to the forum!
There are many variables that affect range. Loaded weight, wind, elevation change, tire pressure, temperature, PAS level used and type of riding surface all come into play. The best approach is to do a series of test rides to get a feel for how far you can go on a charge. Keep in mind the battery gauges on most bike displays are not linear. You will get more miles from the first 50% of charge than with the second. Many here carry a second or range extender battery to eliminate "range anxiety".
Manufacturers often publish range charts for their bikes which may also help.
Again, welcome! Hopefully, someone who owns your particular bike will offer more specific advice.

A *lot* of variables. The best I've done is 32 miles with 4,000 feet of vertical with 1.5 bars left, which I figure about at about 42 miles with 4,200 feet of vertical.
But I only weigh 150 pounds, my bike is way lighter than yours, and has a much smaller motor and I am a fitness rider, so I'm likely to get much greater range even though my battery is smaller.
Yesterday, I got 13.5 miles and 1,200 on the first of five battery bars. So theoretically, even accounting for the fact that we'll likely get a few less miles out of each battery bar (due to their inherent inaccuracy) I could get at least 50-52 miles with 5,000 feet of vertical.
That's a 20 mile and 1,000 feet difference in range! Why such a big spread?
My theory is that the 32-mile ride is just much steeper and has more dirt.
Other things I've found that contribute greatly to range: Tire pressure for sure. For my longer runs, I use tire pressures that are very high by eMTB standards: 50 PSI on a tire rated for 60. That's because I have to ride a lot of asphalt to get to the trail. (By the time I get there, I bet my tire pressure has worn down to about 45 PSI.)
Also: Seat angle. I discovered this by accident: My seat pitched back at one point, just because the bolt was a little loose and I was lazy about getting it back in the right position-- so the front of the seat was angled slightly up. Range was noticeably worse. This week, I adjusted it so it's angled very slightly down, and my pedaling efficiency improved a lot, which helps improve range.
There are other theories, too: If you stop frequently, allowing the battery to rest, some riders report better range. This seems about right to me-- I seem to get better range if I stop more often, and anyway, stopping is NOT optional on some of the routes I take, or not at 64 years old, anyway!

FWIW,
I just checked my battery log book, for my Wart Hog MD 750 bike,
I note every charge and discharge reading when recharging the 2 batteries back to full,
after the battery reading on the display reaches the 44/43v % range,
I can feel/hear the difference when the power is getting low.
Normally the max fill charge rate is to 54.1v to 54.3v, (battery pulled when the green lite comes on), and discharged down to 44.1v to 43.8v's, after all the riding around is done.
It takes 2hrs + 30/45 minutes of charging time using the 48V - 5A -110V~240V OEM Quick Charger, on the 30AH Dual battery's, with LG 21700 cells.
These batteries are also checked with my DCVM and it matches the display's readings.
I have been averaging around 120 to 145 miles per charge, with 99% pedaling and very limited minimum throttle use in Eco 1 step for all my off road trail riding etc.
I don't know if this is good results or not, but I am happy with these results, so far.
