If you're tired of towing a massive trailer just to get two bikes to the track, a dirt bike carrier double might be exactly what your setup is missing. Let's be real, trailers are a huge hassle. You have to find a place to park them, they're a pain to back up in tight spots, and you're stuck paying extra at every toll booth. Switching to a hitch-mounted carrier simplifies everything, provided you've got a vehicle that can handle the load.
It's one of those upgrades that feels like a massive relief the first time you use it. You just slide it into the receiver, strap the bikes down, and hit the road. But because you're hanging two full-sized bikes off the back of your rig, there are a few things you really need to get right before you go flying down the highway.
Why two bikes on one hitch works
The biggest draw of a dirt bike carrier double is the sheer convenience. If you're heading out with a buddy or taking a spare bike for a long weekend, being able to keep everything attached to the truck makes the whole trip feel less like a logistics nightmare. You can still park in a normal spot at the gas station, and you don't have to worry about trailer tires going flat or bearings needing grease.
Most people don't realize how much space they save until they ditch the trailer. You can get into those narrow, sketchy trailheads where a trailer would just get stuck. Plus, it's a lot easier to store a carrier in the corner of your garage than it is to find a spot for a 10-foot flatbed.
Checking your vehicle's tongue weight
This is the part that isn't particularly fun, but it's the most important. Before you even buy a dirt bike carrier double, you have to check your truck or SUV's tongue weight capacity. This is totally different from your towing capacity. While your truck might be rated to tow 5,000 pounds, the tongue weight—the amount of downward force the hitch can handle—is usually only about 10% of that.
When you're using a double carrier, you're looking at the weight of the carrier itself (which can be 60 to 90 pounds) plus the weight of two dirt bikes. If you're hauling two 250cc or 450cc four-strokes, you're looking at roughly 500 to 550 pounds of bike. Add the carrier, and you're pushing 600 pounds or more. You really need a Class III or, ideally, a Class IV hitch to do this safely. If you're driving a mid-sized SUV or a light crossover, a double carrier probably isn't the best idea. You don't want to see your hitch bending or, worse, your front tires losing traction because the back of the truck is sagging so hard.
Suspension matters too
Even if your hitch can handle the weight, your rear suspension might complain. If you notice your truck's nose pointing toward the sky when the bikes are loaded, it's going to affect your steering and braking. A lot of guys who use a dirt bike carrier double regularly end up installing some basic air bags or helper springs in the rear. It's a relatively cheap fix that makes the ride way more stable.
Aluminum vs. Steel: Which one to pick?
When you start shopping, you're going to see two main options: aluminum and steel. Both have their pros and cons, and it really depends on what you value more.
Aluminum carriers are fantastic because they're lightweight. When you're trying to lug a double carrier out of your garage and slide it into the hitch, you'll be glad it's not a 100-pound chunk of iron. They also don't rust, which is huge if you live somewhere where they salt the roads or if you're driving through mud and rain. However, some people feel they flex a bit more than they'd like under heavy loads.
Steel carriers, on the other hand, are absolute tanks. They are incredibly rigid and feel very secure once everything is bolted down. The downside? They are heavy as lead. You might need a second set of hands just to get the thing installed. They can also rust over time if the powder coating gets chipped, so you'll have to keep an eye on that. But for peace of mind, a lot of riders prefer the "over-built" feel of steel when they've got two expensive bikes hanging off the back.
Dealing with the wobble
One of the most annoying things about hitch carriers is the "hitch wobble." Because the carrier's shank is slightly smaller than the receiver hole (to make it easy to slide in), it can tilt and rock while you're driving. If you've ever looked in your rearview mirror and seen your bikes swaying back and forth, you know how heart-stopping that can be.
Almost every dirt bike carrier double will come with—or should be used with—an anti-wobble device. It's usually a simple U-bolt clamp that pulls the carrier tight against the hitch receiver. Don't skip this. It's the difference between a smooth, quiet drive and a stressful trip where you're constantly wondering if your bikes are about to take a tumble.
Tips for loading and strapping down
Loading two bikes onto a dirt bike carrier double is a bit of a workout, especially the bike that goes on the inner rail closest to the truck. You usually want to load that one first. It's a tighter squeeze, and you'll have to be careful not to smack your handlebars against the rear window or the truck's tailgate.
Using the ramp
Most carriers come with a detachable ramp that stores right on the unit. Make sure the ramp is securely hooked onto the carrier before you start pushing. If that ramp slips while you're halfway up, things get ugly fast. It's always easier to have a friend help you balance the bike while you're walking it up, but if you're doing it solo, just take it slow and keep a hand on the front brake.
Tie-down strategy
You'll want four high-quality tie-down straps per bike. Don't use those cheap ones you found in the bargain bin; get the heavy-duty ratcheting ones or high-end cam buckles. A great trick is to use "soft loops" around the handlebars so you don't scratch the metal or pinch your cables.
Once the first bike is on, get it fully strapped and compressed. Then do the second bike. You'll want to check the tension after the first few miles of driving. Things tend to settle once you hit a few bumps, and you'll often find that the straps have a little more slack than they did when you left your driveway.
Visibility and your license plate
One thing people often forget about is that two bikes completely block your license plate and your taillights. Depending on how strict the cops are where you live, this can be an invitation to get pulled over.
Some guys solve this by mounting a spare license plate to the back of the carrier. As for the lights, you can actually buy light kits that plug into your 4-pin trailer wiring. These kits add brake lights and turn signals to the end of the carrier, making it much safer for the people driving behind you. It's a bit of extra work to set up, but it's way cheaper than a ticket or a rear-end collision because someone couldn't see your brake lights.
Final thoughts on the double setup
At the end of the day, a dirt bike carrier double is a game-changer for anyone who wants to keep things simple. It turns your truck into a dedicated bike-hauling machine without the baggage of a trailer. You just have to respect the weight limits and make sure everything is cinched down tight.
Sure, the first few times you drive with it, you'll be checking your mirrors every thirty seconds to make sure the bikes are still there. That's normal. But once you realize how sturdy these setups actually are, you'll wonder why you ever bothered with a trailer in the first place. Just keep an eye on your tongue weight, use a good stabilizer, and you're good to go. See you at the trails.
