Ebike hub kit that will do 25mph without pedalling?

[LarryRogers]

Does anyone know what wattage an ebike hub kit needs to be to get at least 25mph without pedalling?

A hub kit kit with a 600-1000 Watt motor will get you up to about 25 mph. There are plenty of options out there. Depends on your budget.
