Features to know about

Stable Hauling for Heavy Rides: 80 lb Capacity per Bike

Built for strength, the RockyMounts Gigawatt handles big builds without hesitation. Each tray supports up to 80 lbs, perfect for e-bikes, carbon frames, or bikes with fenders. The solid platform design keeps weight balanced while the anti-rattle hitch pin cuts down movement on the road. With room for two bikes and 15" between trays, it stays steady and prevents contact mile after mile.

Easy Loading with Included 48" Ramp

Lifting heavy bikes is no longer a chore. The included 48" ramp lets you roll each bike into place instead of wrestling it overhead. Once loaded, ratcheting hooks secure the front wheels while sliding rear wheel straps fit bikes with different wheelbases—up to 55" long and tires up to 4.5" wide. It’s a simple, secure way to get even the heaviest rides mounted fast.

Access Gear Without Unloading: Tilts with Bikes Loaded

Getting to your cargo doesn’t mean unloading your bikes. The Gigawatt’s front-mounted hand lever lets you tilt the rack down, even when fully loaded. Whether you’re reaching for a jacket or gear in back, one quick pull gives full access. When you’re done, it folds up neatly to stay out of the way until the next ride.

Locks Built In: Bikes and Rack Stay Secure

The Gigawatt keeps everything locked down. Keyed-alike locks secure both the bikes and the rack itself, so you can step away knowing your setup is protected. The aluminum frame with black powder coat finish adds durability and corrosion resistance for years of use.

Ready for Every Ride: Fits a Range of Bikes and Wheel Sizes

From compact 20" wheels to full 29" setups, this rack adapts easily. It weighs just 52 lbs yet carries the toughest loads with confidence. Whether you’re hauling electric, carbon, or heavy bikes, the Gigawatt delivers a strong, stable way to bring your rides along for every adventure.

Video Transcript for RockyMounts Gigawatt 2 Bike Rack Test Fit - 2026 Ram 1500

Hi, I'm Daniel with etrailer, and today we're gonna take a look at the RockyMounts Gigawatt Bike Rack for 2 Bikes on our 2026 Ram 1500. A lot of people that own a truck will get a bike rack for their hitch because if they're going on long road trips, they wanna pack their bed full of their gear. And if you have a tonneau cover like our neighbor today, they're not gonna be able to fit a bike in here. Now a nice feature with this is all the touch points are gonna be blue, so they're really easy to locate, but it's gonna have a tilt feature so you can tilt this away and you can more easily get to the things in your bed. Now, open the tailgate and it is a really tight fit, so you wanna make sure that pedal's outta the way and get this open. And, as you can see, it's super-tight.

It is touching the tire a little bit. So if that's something you're concerned about, we do offer bike racks that will swing away, so you can just have that swinging away out of your way to get to your bed. All the attachments points are gonna be on your wheels, so if you have those carbon frame bikes with those nice paint jobs, you're not gonna have to worry about scratching anything. And a really nice feature is this comes with a ramp. So our hitch does sit pretty high off the ground like most trucks do.

So this is gonna be a huge game changer, especially if you have those e-bikes that are really heavy to get this on and off pretty easily. So you can see the back end is slanted down, so that'll help with it gradually coming off. And I'll show you how to take this off. You just wanna take the strap off the front, hold up, get that out of the way. Now that we've got everything detached, we can just simply roll this down and hit the trail.

Now I'll get you some measurements. So from the rear bumper to the farthest point on this bike rack, it's gonna be about 38 inches. And I'll tilt this up so it hugs the back of your truck here. We'll get that measurement again, and we're looking at right about 20 inches. And for ground clearance you have about 18 inches.

So for a truck this size, you're not really gonna have to worry about bottoming out. Now do keep in mind when it's folded up like this, you are impeding the vision of your license plate so that's just something to keep in mind. The shank on this bike rack is gonna be two inches by two inches, which is gonna be your standard. And it comes with a pin. And this has an anti-rattle function, but you will need a 19-millimeter socket to tighten this up. And it comes with two locks and they're gonna be key-to-like, so one's gonna be for your pin, and then the other lock is going to be for your cable to secure your bike. Now as far as weight capacities go for this bike rack, this is definitely a heavy-duty one. It's 80 pounds per bike. So again, if you have those e-bikes, no worries. I think this bike rack is a great fit for the Ram. It's gonna work for any of your applications. And that just about does it for the look at the RockyMounts Gigawatt Bike Rack on our 2026 Ram 1500.

So far so good! Haven't tried it with the bikes yet. Easy installation. It's solid. Been driving with it on the car. No rattles or vibration. Easy tipping for back access to a Kia Sorento RV. Doesn't block back view or rear camera.

*Edit*
Wanted to add to my review of my RockyMounts Gigawatt Bike rack. Finally got to put the bikes on it and go. Love it. Solid as a rock. My wife who is 75 had both bikes on and tied down in less than 10 minutes. Love the rack!

You wife may be faster than Speed Racer! I'm glad getting the bikes on the rack is so easy, and fast. Do you and your wife do a lot of biking locally or do you do any traveling with the bikes?

@GwendolynYWe do a lot of local riding and places within 50 or so miles. Traveled to Jekyll Island which is about 100 miles. Looking forward to doing it with our new rack. Our old rack worked, but was a pain to use. So far very happy with this rack!

@Jack I checked out Jekyll Island and it looks like it was worth the drive! I've really have only visited Atlanta, but you have perked my interest in Jekyll Island.

@Gwendolyn It's a little pricy, but it is worth it. A lot of bike trails. Great beaches! We usually stay for a couple of days. Great times the few times we have gone. You will have a great time if you go!

Very well constructed. What I had to put together was easy to assemble. When I put the tire holder on I used a clamp to bring the sides together and the bolts lined up perfectly. Bikes load up with ease. Highly recommend!!

  • Best Way to Store Ramps on Rocky Mounts Gigawatt Bike Rack
    Hi Anne! At this time, there isn't a more elegant solution. The ramp of the RockyMounts Gigawatt Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount # RKY37MR is not designed to stay on the rack, so typically it's stored inside the vehicle to prevent loss or theft and that's truly going to be the best option. You could use something like Yakima Cinch Straps w/ Padded Cam Buckles - 16' Long - Qty 2 # Y05006, but with that you're running the risk of them being lost on the road and having to...

  • Does the RockyMounts Gigawatt Bike Rack RKY37MR Work w/ a Tern Quick Haul Cargo E-Bike?
    Yes, it will! The RockyMounts Gigawatt Bike Rack for 2 Bikes item # RKY37MR has an 80 lbs per bike capacity and works with tires as small as 20". The placement of your front fender will not interfere with the locking clamp. The Gigawatt Bike Rack item # RKY37MR mounts to a 2" receiver and weighs only 52 lbs. It is compatible with all motor vehicles, motorhomes, 5th wheel trailers, and flat towed vehicles. It is not rated to be used behind a travel trailer. I have linked a review video...

  • Can The RockyMounts Extender RKY10011 Be Used With A RockyMounts Gigawatt Bike Rack?
    Hi James! The RockyMounts Hitch Extender LS w/ Hitch Pin and Lock - 2" Hitches - 8" Long # RKY10011 can indeed be used with the RockyMounts Gigawatt Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount # RKY37MR. Just be aware that using an extender like this, even with its anti-rattle locking hitch pin, it will cut the carrying capacity of your hitch in half. With that said, I would not use bikes over 40 pounds when using it to keep everything safe. What kind of bikes are you wanting to...
