The Swagman E-Spec and the Hollywood HR1700 have no provision for a tramp and so the user with two bikes is going to have to lift a 70 lb bike waist high and lean over the rear most wheel holders to put the first bike in place. The 1up rack has a good ramp but it uses wheel holders that are best used with bikes without fenders. If you really thought this through you would already know this.

And by the way the Thule and Yakima and Hollywood and 1up e-bike racks have been out of stock for many months. The only rack at this time that will hold two 70 lb e-bikes and is available to buy is the Swagman E-Spec (if one searches diligently as they are scarce) and that means no ramp.
