Video Transcript for Curt Clamp On 3 Bike Rack for 2 Inch Ball Mounts Review

Today we'll be taking a look at the Curt clamp-on three bike rack for 2-inch ball mounts, part number C18013. The Curt clamp-on bike rack is the perfect solution for carrying up to three bikes while hauling your camper or your trailer. It simply clamps around your existing ball mount, transforming it into a three bike rack. The duel arms are going to provide great support for our three bikes, we've got two reflectors here at the end to make it more visible at night. The cradles themselves are adjustable along the duel arms, they're made of a soft plastic, they have cut-out grooves to accommodate our brake lines and cables, and an adjustable rubber strap secures our bike in place. The whole bike rack itself has 135 pound weight capacity, it's made of a sturdy steel construction with a nice black powder coat finish, so it's going to resist rust and corrosion. Now let me get into some of the features and and go ahead and show you how to get it installed.

Now if you're doing some towing too, so we've got our extended ball mount on here today. First thing we'll do is we'll swing up our arms, then we'll put the pin in place, now we can bring it up and place it on our shank. We want to make sure and leave enough room for out coupler, so we're going to place the bike rack as close to the vehicle as we can. Once we get it on there we're going to open it up, and we'll push down on our lever to snap it in place. As you can see, that secures the base of our rack around the ball mount shank. The next thing we'll do is we'll go ahead and secure our stabilizer straps.

On our truck here, we're going to go on the side of our tailgate, but if you we're on an SUV or a car, you would just secure it to the rear hatch or trunk. Let's put that in place and pull on our strap just like that. We'll repeat that same step on the other side. We're out here at our trailer and it's a good idea to go ahead and connect it, that way you can see how much room you're working with before you load up your bikes. Now we can go ahead and get ready to load up our bikes. We need to make sure that our straps are undone first, now let's come up and over, work my way to the back, then I'll bring my straps over, make sure they get nice and connected, just like that.

Now with two more bikes loaded up, let's go ahead and take it out and see what it looks like in action. Here in our test course, let's first go in to our slalom. This is going to show side-to-side action, such as going around corners or evasive maneuvering. Then on to our alternating speed bumps, this is going to show a twisting action such as going over uneven pavement or potholes. Finally on to our solid speed bumps, this is going to show an up and down action such as pulling in and out of a driveway or out of a parking lot. That's going to complete our look at the Curt clamp-on three bike rack for two-inch ball mounts, part number C18013.

Bike rack arrived in a timely manner and was securely packaged. The rack appears to be sturdily built. Rack requires a lot of downward force to attach it to the hitch bar. Someone taller and stronger might have better luck. Probably good because it attached very securely. The side straps for attachment to the trunk are a good stabilizing feature although their attachment to the rack was not well thought out. The rubber straps for attaching the bikes to the rack are very sturdy and stiff and again difficult to attach but were secure. Loaded 2 women's bikes with cross bar accessory and the rack bars were almost too wide for the accessory application. I removed the bike front wheels and turned the handlebars so they aligned with the bikes so the bikes could be placed closer together. Space for three regular or large frame bikes may be inadequate but ok for 2. The pin that secures the rack in the open position is spring loaded and there is an adjacent hole where an auxillary pin can be inserted for extra security. I will definitely get one and use it. Last but not least, make certain you release the spring loaded pin and lift up on the ring handle while standing to the side of the rack. The rack releases with the same force required to secure it. This rack allows me haul two bikes and a cargo carrier at the same time. 273057

This is the best product online. I had to do a few adjustments to make room for the clamp on the trailer hitch. The particular ball hitch I had had a reinforcement welded to the ball which I had to have a piece taken off. Once it was filed down the clamp worked like a champ. Now I have a $200 bike rack that I purchased a year ago that is obsolete. The product arrived early and in good shape. I would definitely buy this bike rack and use this company again! 410656


Thank you for your review. It looks like you have a draw-tite ball mount with a high rise. I cannot tell exactly how many inches of a rise your ball mount has from the provided photo but manufacturers like draw-tite will weld a reinforcement on the underside of ball mounts with a lot of rise/. We do not recommend to trim these pieces because it can affect the structural integrity of the ball mount. However we do have options for ball mounts without the welded reinforcements that will allow the curt bike rack part C18013 to clamp around them. Draw-tite part #40332 provides a 5 rise and is rated up to 16k of towing weight. If you need more rise, Anderson ball mount part #AM3511has a 9 rise but only allows for up to 8k in towing weight. Both of these ball mounts will work with this bike rack.

The main reason that I purchased the C18013 bike carrier was that I had just also purchased the trailer hitch to mount it to. I was pleased with the quality and heavy gauge of the steel. It is very easy to mount the unit to the hitch bar. The clamp has a built in lock pin to insure it does not come loose. Be sure to use the trunk or hatch back straps to keep it from rocking left to right. The only concern is the shipping box they use. Since the bike carrier is heavy gauge, it caused the box to split open a little. No real problem, since everything was still there. I'm very satisfied with the purchase. 441678

- C18013


Strong build, very easy to put together, and disassemble for storage. The only downside is the metal loop is too short, so I use a strap to pull it up in order to not injure my hands. So far I drive 400 miles and the bike didn't even move. 436410

- C18013


Rack fits tightly on hitch with more than enough strap length to reach the sides of the rear door on a 09 Yukon. The rubber cradles grip the bikes well. The unit doesn't move or shake. I will have to remove the front tires from the bikes to give enough clearance for the trailer to connect to the hitch but otherwise I believe it will work perfectly for a vacation trip towing the boat. 268267

Extremely fast shipping. Awesome customer service. Products was as described and good quality! Easy to install and very sturdy. Would recommend. 276203

The shipping was fast! Easy to set up. Looks very sturdy. I have not tried it but from the looks of it, it is better than the I bought from a discounted store. When I go camping in a few weeks, I will give the full review. 335852

Works very well and have used on several occasions. I have a pop up tent and it allows me to have the bicycles in between my tailgate and hitch. Make sure ball hitch has enough room for it to clamp on. 431514

I'm very pleased with this product. I reserved ithe product faster than I though I would. It will work great when I'm pulling my pop up camper and I will be able to take my bikes with me. 411810

Love the product, just be careful when you remove this since it's under pressure it has a bit of kick when released. We're just thrilled that we can now haul our bikes with the camper. 457544

Just what we needed. Perfect for pickup tow vehicle. Holds bikes low out of the wind with little movement. Bed still accessible. No interference with trailer tongue. Easy to install. 448748

A superb product. Fits well behind my avalanche and between 21ft Bantam hybrid trailer. So easy to install. Ordered Tuesday and delivered by Friday. Great service. 425402

We installed the rack and it will solve our bike transportation! Our good bikes travel inside the SUV, these bikes, are our "running around" heavy cruisers. 473903

The only thing I do not like is when you use the handle to take it off. It springs and hits your hand ever single time. Other then that it is nice. 429064

Ask the Experts about this Curt Hitch Bike Racks
Do you have a question about this Hitch Bike Rack?

  • How do I use a Bike Rack and Pull a Trailer at the same time
  • We carry a very handy 2 inch ball mount for this exact application. The part is # D210. The ball mount slides and pins into your hitch and the top receiver will accept 2 inch bike racks and hold them above the ball. The Ball Mount has a 500 lb tongue weight capacity, which means that the bike rack and the bikes on it as well as the trailer tongue weight cannot weigh more than 500 lbs or the tongue weight capacity of the hitch, whichever is lower. We also have a bike rack that clamps...

  • Carrying Bikes While Towing a Trailer with Propane Tanks Mounted on the Front
  • This is the age old question since the dawn of towing bike racks. The only way to figure it out is to try it. It will likely reduce the turning radius of the trailer. And depending on where the tanks are, they could be the likely point of contact. You could avoid all of that by using the super sweet Bike Bunk Trailer mount bike carrier # CC-275. This carrier and a 2 inch receiver for a bike rack and the distance from top of A-frame trailer to top of cross tube is 33-1/2 inches. It...

  • Can Women's Bikes Be Carried on the Curt Clamp-On 3 Bike Rack # C18013
  • To carry a women's bike on the Curt Clamp-On 3 Bike Rack # C18013 is pretty easy actually. All you need is the adapter part # UB01. This adapter attaches to the seat post and the steering stem to provide you with a horizontal attachment point for the bike racks to attach to. I attached a review video for this for you to check out as well.

  • Options for Hauling Both Bikes and Cargo in a Hitch Mounted Carrier
  • If you are looking to carry both bikes and carrier in a hitch mounted carrier, your best bet would be to go with something like our Hollywood Racks Sport Rider SE2 Platform 2 Bike Rack with Cargo Carrier, # HR1450-85. The Curt Clamp-On, # C18013, is a ball-mount-mounted rack that you mentioned will both provide the same amount of rise. From the bike cradle to the top of the receiver clamp measures 27 inches (I included a picture for you) so unless you just plan on carrying very small...

  • Is a Locking Cable Included in Both Heininger Advantage HE1011 and Curt C18013 Towing Bike Racks
  • The Curt Clamp-On 3 Bike Towing Rack # C18013 does include a security cable to lock your loaded bikes. But please note that the rack does not includes the lock, just the cable. You can add you own padlock like the Roadmaster # RM-305. I have linked videos of both racks to better illustrate their features and to help you make your decision.

  • Does the Heininger Advantage SportsRack V # HE1011 Interfere With Turn Radius Capabilities
  • My technical contact at Heininger told me that they have not had any complaints of the Advantage SportsRack V # HE1011 interfering with anyones turn radius to date. Just to give you a full idea of how adding the Advantage SportsRack will effect your set-up I went to the warehouse and measured one and have the measurements noted in the attached picture. The arms extend out 14 inches, so you are basically adding about 18 inches to the back of your tow vehicle when you load your bikes...

  • Does the Curt Clamp-On 2 Bike Rack Need Additional Stabilizing Straps
  • The Curt Clamp-On 3 Bike Rack, part # C18013 does not require any additional straps for stabilization while carrying bikes. If you would like additional immobilization, or would like to prevent any shifting you could add the Roadmaster Quiet Hitch for a 2 inch hitch # RM-061 for additional support at the hitch. When you are using this bike rack and towing a trailer please remember that the weight of the trailer hitch, this bike rack, which is 13 pounds, and the weight of the bikes...

  • Can Curt Clamp-On Bike Rack be Used on 2-1/2 to 2 Inch Adapter and Weight Distribution
  • First to determine if Curt bike rack # C18013 will fit your existing set up you can measure the amount of free space available on the weight distribution shank. The clamp part of the ball mount requires just 1-1/2 inches of free space on the shank. It is not meant to fit on a 2-1/2 inch shank or adapter/extender. The regular e2 weight distribution shank measures 4 inches from the center of the hitch pin hole to the support gusset. On most hitches the distance from the center of the pin...

  • Using a Hitch Mounted Bike Rack and Cargo Carrier at the Same Time
  • If you are using Rola cargo carrier # 59502 or # 59507 then clamp-on bike rack # S64600 will not work because of the bend in the shanks on those bike racks. It could potentially work with the Dart, # 59550 as long as there is at least 3-1/8 inches of free space on the shank to mount it. Curt bike rack # C18013 requires just 1-1/2 inches of free space so it is more likely to fit. I do not recommend using a hitch adapter because doing so will reduce the tongue weight capacity of the...

  • Towing a pop Up Camper and Carrying 2 Bikes at the Same Time
  • With 2 bikes in between the truck and the trailer the turning radius will not be reduced all that much but every situation is different so the only way to know for sure is to try it. Another option, instead of using the multipurpose ball mount # D210, is to use the Bike Bunk, # CC-275, which mounts on A-Frame trailers and can hold a bike rack. The bike rack will have to be rated for use on a trailer though. For that I recommend the BikeWing, # B01311. I have linked videos on the Bike...

  • Fit of Curt C18013 Clamp-On Bike Rack on 2014 Lexus GX460
  • The Curt # C18013 Clamp-On bike rack can indeed be used when not towing a trailer. The rack has a 135 lb total capacity. In order to carry the bikes level and to provide maximum ground clearance, I'd highly recommend an adapter bar like part # 64005 be used. The bike rack doesn't have any built-in locking mechanism, but the clamp that locks the rack on to the ball mount can be locked using a coupler lock like part # 7691. The rack includes a cable that can secure the bikes to the rack...

  • Trailer Hitch and Wiring for a 2012 Toyota Prius
  • Draw-Tite trailer hitch # 24847 has a square cross tube and a little bit different design than Curt hitch # C11276 which has a round cross tube. Both bike rack and hitch manufacturers agree that on a Class I trailer hitch the maximum capacity is 2 bikes. The issue is not how much weight would be on the hitch it is where that weight is placed relative the the hitch receiver. The further the weight is away from the receiver the more stress and torque is put on it like using a cheater...

  • Can a Towing Bike Carrier be Used with a Weight Distribution System
  • Using a towing bike carrier such as # C18013 adds to the tongue weight of the trailer which is a critical part of determining the proper weight distribution system and setting up that system. Because of that I do not recommend using this type of carrier when using weight distribution. What you can use is the Bike Bunk, # CC-275, though it may require moving some things on the A-Frame to attach it. Then you could use a bike carrier that is approved for use on a trailer such as the BikeWing,...

  • Can a Womens Bike be Mounted to Curt Towing Bike Rack C18013
  • All you will need to mount a women's bike or bike with a step-through frame on towing bike rack # C18013 is a bike adapter bar such as # 64005. The bar will clamp around the seat post and handlebar gooseneck and provide an artificial top frame tube allowing you to carry the bike more level. I have included a link to a video showing how the adapter works.

  • Carrying Bikes and Towing a Trailer at the Same Time with a 2014 Mitsubishi Outlander
  • I have a recommendation for you but like you said an adapter that allows for a rise in the shank and has a receiver for a bike rack is not available. What I recommend is to use super extra long ball mount # 80232 in the rise position to be a 3/4 inch rise (the tongue weight of the trailer will pull it down some closer to level). Then you can use a towing bike rack such as # S64664 for 2 bikes or # C18013 or # S64600 for 3 bikes. I have included links to video reviews of all of these...

  • Recommendation for a Bike Rack for Use When Towing a Trailer with a 1996 Jeep Cherokee
  • There are a couple of options for you to carry a bike a rack and tow a trailer at the same time. First, you can use a towing rack. The rack you have referenced, # S64101, would be best used on a ball that mounts to the bumper of a vehicle. Instead, I recommend the Curt Clamp-on, part # C18013. It fits around a ball mount shank. A couple of things to note about this method are the ball mount length and the tongue weight. This bike rack requires that the ball mount have a distance of...

  • Flat Towing a CR-V Behind a Motor Home and Carrying Bikes at the Same Time
  • There are only certain bike carriers that are rated for use at the back of a motor home. Towing carrier # C18013 is not one of them so I cannot recommend it for you. that is also probably why you do not see any reviews with a similar set up. But not to worry because I do have a solution for you. You can use a dual hitch receiver adapter such as # RM-077-4 with a 4 inch drop or rise or # RM-077-2 with a 2 inch drop or rise. Then in the upper receiver you can use a motor home approved...

This bike rack will not work with aluminum bumpers, spot welded bumpers or c-channel bumpers.
