Best way to move a E-Bike across country?

I need to get an ebike across the country and looking for ideas. Here is what I have considered so far...

1. Rent a car and drive it. 3-days @ 12 hours a day
   1. Cost: Gas + hotels + food
2. Greyhound bus
   1. Cost: Ticket + packaging + baggage fee + food
3. Ground shipping company
   1. Cost: Packaging + shipping + (need to figure out how to retrieve package if it is too large for uber/lyft)
