Welcome to the EV9 family! For four bikes, including your e-bikes, a robust platform rack is key. Many EV9 owners find success with the Kuat Piston Pro X or NV 2.0, and 1UP Super Duty. These often offer good liftgate clearance and minimize sensor issues, though some activation is possible. Aerodynamic impact exists, but these designs are generally efficient. Ensure a 2-inch hitch for stability and capacity, as e-bike racks often require a Class 3 hitch.

Hi there! Just a heads-up: the EV9's rear sensors are seriously sensitive and will likely trigger the auto-braking unless you manually disable them every time you reverse. It's a bit of a pain, honestly.

For your situation, I would suggest the Kuat NV 2.0 2-Inch Hitch Rack with the Kuat NV 2.0 2-Bike Add-On. I've used Kuat for years, and while I'm still learning the EV9's quirks, the tilt-away feature is solid. It clears the power liftgate easily, even with heavy e-bikes loaded. Range takes a hit, but that's just the EV life! Good luck!

Honestly, I totally get the anxiety about those EV9 sensors—they are incredibly sensitive. For your specific heavy e-bike setup, I would suggest looking at the 1UP USA Super Duty Double Hitch Rack with two 1UP USA Super Duty Add-On kits. From a technical standpoint, the 1UP is a tank. It’s made of solid aluminum, so it handles the 55lb weight of e-bikes without that terrifying highway wobble, and the aero impact is actually better than most because of its slim profile.

Regarding the liftgate, the 1UP has a great tilt-down feature, but you have to be careful with the pedal placement of those heavy bikes to ensure total clearance. As for the tech, the EV9's 360-camera will definitely see the rack, but I've found that because the 1UP is so modular and doesn't have a giant center mast, it interferes slightly less with the view than a Kuat. That said, you'll still likely need to toggle off the rear braking assist in the settings. It’s a bit of a trade-off for safety, but worth it for the peace of mind. Hope this helps with your decision!

Hi there, I've been thinking about your question since I just went through a similar headache with my EV9. Honestly, it's been a bit of a love-hate relationship with the tech. While I'm obsessed with the car, the rear sensors are... well, they're kind of a nightmare with a rack on. Unfortunately, I had some issues with the super high-end brands being way too heavy for me to manage alone, especially when you start adding extensions for four bikes.

Since you're looking for a more cost-conscious but reliable setup, I would suggest checking out the Hollywood Racks Destination E Hitch Bike Rack for Electric Bikes. It’s designed specifically for heavy e-bikes (up to 70 lbs each!) but doesn't have that crazy "premium" price tag of a 1UP. To get to four bikes, you'd actually be looking at two separate racks or a heavy-duty 4-bike setup like the Hollywood Racks Sport Rider for Electric Bikes HR1500.

From a practical standpoint, the aerodynamics definitely take a hit. I noticed about a 15-20% drop in highway range when hauling four bikes. It’s not as good as I expected, but that's just the reality of pushing a brick through the wind. Also, about those sensors—tbh, there isn't a rack that magically hides from them. You’ll likely have to hit the "Parking Safety" button to mute the beeping every time you reverse. It's frustrating, but you get used to the ritual. Does your EV9 have the factory tow package or an aftermarket hitch? That might change how much clearance you get for the liftgate tilt! Hope this helps a bit!

Seconding the recommendation above about those pesky sensors! Honestly, I’ve been hauling gear for over fifteen years and the EV9’s tech is some of the most sensitive I’ve encountered. When you're dealing with heavy e-bikes and a high-tech EV, the "safety-first" approach is non-negotiable. You need a rack that doesn't just hold the weight but maintains the integrity of your hitch receiver over long hauls.

Since you're worried about aerodynamics and the 360-degree camera, I really think the Thule T2 Pro XTR 2-Inch Hitch Bike Rack is worth a serious look. It has integrated wheels that make it way easier to move around when it's off the car—trust me, your back will thank you given how heavy these racks get! It also tilts further than most, which is a lifesaver for that EV9 power liftgate.

One pro tip from my years of doing this: if the sensors keep braking, you can sometimes mitigate it by using a hitch extension like the Kuat Hi-Lo 2-Inch Hitch Extension, though that can change your tongue weight capacity, so check your manual first! Also, for your e-bikes, definitely look at the Thule Epos 3-Bike Hitch Rack because its telescopic arms are amazing for avoiding frame contact on expensive carbon or heavy-duty e-bike frames. Stay safe out there!
