Although it can carry two bicycles, the carrier does not sufficiently clear the spare tire on my E21 to allow a bicycle to fit on the inside tray. I wish Escape had aligned the hitch receiver several inches outside the rear bumper to give a bicycle carrier better clearance of the tire. But the tire takes up about 6inches of the carrier mount. When my wife brings her bicycle I suppose I will have to remove the spare and carry it in my tow vehicle. I don't envision any problem with this carrier holding 2 bikes.
I don't care for the extension because of the instability and sway it would have. The bike rack hitch itself is threaded and it comes with a bolt instead of simply a pin so it screws tight into the mount. It is rock solid - and difficult to steal since the thief would need a large wrench or ratchet to get it off. I just wish the darn Escape hitch mount were extended farther out. But it's not and wishing won't make any difference.
