The point of a hybrid is that IC engines fall on their faces, so to speak, when dealing with overcoming inertia. Spooling up consumes crazy amounts of fuel. Electric, on the other hand, has crazy torque and minimal loss to spooling, heat being the problem with elecs, but in hybrids they're utilized almost solely for the torque.
So, in a sense, our bikes are hybrids, but instead of a ridiculous amount of super earth friendly heavy metal batteries and electric high torque short burst motors, we have feet. That's why we get 150mpg.
Unless you run from a dead stop by revving and dumping the clutch...but if you do that, please stop
