Say cars are 10x the weight and drive 2x the speed of an electric bike. That’s 40x energy.
Additionally, bikes are more likely to have less erratic go/stop behavior, so even more efficient. For example, I’m much more careful to coast on a bike than a car because it’s my energy.
Simple physics demands that this use less energy.
E = mv^2/2.
