The best streamlined electric bikes are still over 100 Wh/ mile at 100 kph. Some electric bicycles can get to 30 Wh/ mile but at a much lower speed of 30 kph.
90% load may be power efficient, but is it also fuel efficient? If i used a tiny engine and had it run all the time at 90% load to produce 15hp for bare minimum cruising at 65mph, will i get better mileage than a 250cc cruising at 65mph?

That almost basically describes the character of a serial hybrid. So maybe i'm better off going that route?

On the EV album website, there are several conversions of 200-250cc motorcycle frames that get 100wh/mi and can do 65mph+. Which isn't to say it gets 100wh/mi at 65mph! Probably worse, cause you lose tens of miles of range due to drag at 65mph. But if i get it from .5cd down to .16cd, I'd say i can improve mileage and range a lot!

Later, i'm gonna post about some estimates and benefits of a serial hybrid motorcycle. There is one unfinished serial motorcycle on the Ev album that i found!
