Hi Pease, Yes, the mark is a long way off in my opinion. The Al Gore crowd would have us all walking -except them.
The overwhelming favorite fuel here is gas.
I built a e-bike based on scooter parts (to be legal in this overtaxed, over-regulated state), only it has an onboard generation system powered by GAS.
Batteries are the big problem. Cheap=short life/low range.
Super expensive batteries are great but I could build a whole gas bike for the price of them.
Batteries work poorly in real cold weather.
Hang around and learn a lot at no cost at all. Welcome to Motorbicycling!
