The lighter the bike the better range is as well.
My 24v small 208wh battery gives me 25 miles on my 15kg gravel bike and my 36v 216 ah small bottle battery gives me also much the same if not a mile or two more.
Range is hard to define as each use/user is different, topography, head winds, fitness, all up bike weight, cut off speed, rider fitness and assist level all have a part to play.
Max range though in lowest assist with some unpowered riding is the way to go if one wants to eke out the most.
