> Ah, there's the rub. It'll have a range of ~90 miles. Since motorcycles all have pretty similar weight and aerodynamics (specifically: very bad), you can compare different models with the same power pretty reasonably. The efficiency of the battery, electronics, and motor are all >>80%. If they were lower, they'd be on fire. The difference between 80% and 90% efficient is only 12.5% extra power to the wheels. The actual energy lost is all in the drag and the speed you ride- even the weight doesn't matter much because the tires don't deform nearly as much as car tires, while the air drag is actually about the same as a sedan. For comparison a gas motorcycle will get 150-200 miles on a tank, but even that is very very dependent on how you're riding.
