Wally;
You do not want to fool with any problems at this point in life do you?
1) Buy a top quality hitch mount lockable carrier and leave your ebike on it.
2) Buy a top quality powerful automobile inverter, have it installed professionally on your vehivle as required, so that you may charge your ebike battery as you drive.
Ride where allowed, perhaps on the road because you are lighted, licensed and helmeted, as you may enjoy without worry about theft of services or being trespassed or ticketed.
Ride On I am experienced with pushing the boundaries on land and sea, pay your way up front and avoid trouble.
Mike
