The trick is finding a rack that is under 30 lbs that will support a 60+ lb ebike and consider what you may have in the future or whether you ever want to have two bikes on the rack. Fenders are not an issue but racks usually supprt bikes with 3" or narrower tire and may need adapters for wider tires.
Separate problem is finding a rack in stock. Hollywood racks for e-bikes have been out of stock since October of last year. 1up is supposed to have more by June or July.
