I figure that an Ebike is going to use 15-50 watt hours per mile depending on speed and design.
An electric motorcycle is going to use 75-150 watt hours per mile depending on speed and design (55mph should be close to 100 watt hours per mile)
An electric cars range from 250 watt hours per mile up to 450-500, again depending on design and speed! and an electric pickup trucks with lead acid batteries seem to see 500+ watt hours per mile used.
Lithium batteries help in many ways, they are lighter, for example my motorcycle is going from 400 pounds of lead acid batteries (36v 210 amp hour rated capacity, or 80ah to 100ah usable capacity) to 120 pounds of lithium batteries (48v 100ah rated capacity, ~80ah to 90ah usable) and people who have put lithium batteries in their electric cars say that they get 1/3 more range with the same usable capacity on paper because the batteries handle discharge rates much better! tires have less weight on them, you are accelerating less weight and you have less voltage drop so you have less line loss.
