having lived with lithium battery bearing electric scooters i can confirm that the weight to power ratio of lithium ion batteries leaves something to be desired

my scooter would charge for 3-4 hours at 36V and would give me about 10-15km range

part of the reason why it has such a wide variance is because the amount of energy required depends entirely on the traction of the wheels (which can vary on different surfaces, as well as rolling resistance and rotational inertia, ie wheel weight) and the average of the slope of the path and the variance of the cargo weight (people tend to vary in weight during a day up to 3kg up and down depending on hydration and food intake and so on)

my scooter was limited to 350W of torque and this was often not enough for some slopes, also, and the dynamic range possible in an internal combustion engine is much wider, gasoline is the best for width, diesel has more KW but less torque, and two stroke gasoline has a narrow band of optimal torque

torque is how steep the slope is and KW is how tall the slope can get, and in internal combustion engines this is a distribution curve across the rev range and can be tweaked with turbos, superchargers and other combustion modifiers

all in all, the engineering reality is that the best all round vehicle would be a turbo diesel hybrid, with a fairly precisely picked balance of battery weight, chassis weight, wheel weight, type of tyre, wheel diameter, and of course aerodynamics

this would give you the widest power range with the sharpest torque response and the longest overall distance per overhead weight

this is why it's retarded to say EV is better, because EV is better for some workloads, and diesel is better for others, and two stroke still others, then there is gasoline, and nitrous, and methanol

simple answers make simple minds happy, sorry not sorry
