Bike Frame Adapter for Hanging-Style Carriers

Rhino Rack Adapter for Bike Frames

If you have a bicycle with an irregular frame - such as a woman's, child's, or full-suspension bike - you may need a bike adapter bar to carry your bike on a single- or dual-arm, hanging-style bike rack. This adapter bar creates a horizontal mounting point that ensures your bike will hang level on the rack for safe transport.


Telescoping Tube and Easy-To-Use Collars

Rhino Rack Bike Frame Adapter

This adapter telescopes from 23" to 29" long. The ends of the telescoping tube have plastic collars that clamp around your bike's seat post and handlebar stem post. To open a collar, push down on the tab and slide it open.


Rhino Rack Frame Adapter Clamped Bike

Place the collar around your bike frame and slide it back into place until it secures with an audible click. These plastic collars help protect your bike from scratches. And the black powder coated steel construction resists rust.

Rhino-Rack Bike Frame Adapter Bar for Women's and Alternative Frame Bikes - RRRBCA021

Average Customer Rating:  4.7 out of 5 stars   (129 Customer Reviews)

Bought it for my wife's new, as yet undelivered, bike. I've used these before and this one looks very heavy duty and I expect it'll provide excellent service. The fit and finish are well done. The ends that will attach to the bike appear to have a very robust material coating that will protect the bike's finish when used. I expect the adapter bar will work very well and provide years of service with little maintenance required, if any.


Comments
The adapter bar for my wifes bike has worked perfectly. Its easy to install and remove and is very secure once installed. I added some foam to protect the bars finish from the bike rack J-hook and it still looks like new. Very satisfied with the adapter bar.

The Rhino-Rack is well made and makes loading a woman's bike easier. It fits well with this rack.



by:

Once I figured out how to use the Rhino-Rack Bike Frame Adapter Bar for Women's Bikes, I found it most helpful to mount and carry such a bike on a rear or trunk-mounted bike rack. The directions were not clear how to extend the bar and my attempts to do so were insufficient. Finally, and purely by accident, I exerted enough pull to do so; the directions should be more explicit. The etrailer person who helped me was most helpful and willing to exchange what I thought was a defective product. Also, etrailer was most timely in sending the bar. If and when I have a need for another etrailer product, I will certainly use them. They were great.



by:

Adapter bar is just what we needed to secure our step-thru e-bike on our bike rack. Fast delivery, and a great price made our purchase perfect!


Comments
It is strong and fits our step thru bike very positive. Great product.

I initially ordered a Swagman adapter bar, but after waiting more than two months the item was still not in stock. I was offered the alternative Rhino-Rack, which was shipped immediately. I have not yet used the adapter bar, but it appears to be what I need.



by:

This rack has been AWESOME! I have no complaints, and have not found anyway that this could be better. RECOMMEND!



by:

Excellent quality. Holds bikes on rack through the roughest of roads. Easy to attach and take off.



by:

We have a bike rack with trays, so bikes sit on it and arw racheted down instead of hanging. Our new bikes are Townie step-throughs so could not ratchet down. This appears to be perfect for us! And Adam at e-trailer was a great help!



by:

Didn't fit the bike that I was trying to adapt to the rack. Ended up paying $[XX] to return it. Not pleased.



by:

My bike would not fit on inside rail as handle bar contacted RV. Outside rail worked very well. Trip from AZ to CO finished without incident even over significant bumps

Great quality items and shipped on time.

Works great for our radcity step thru bikes.

I originally placed an order for the Thule frame adapter not realizing the item would not arrive until May, which is too late. Within minutes of me placing the order for the Thule, George sent me email to let me no about the May delivery date and offered to switch it out for a similar item in stock. George already had replacements linked in the email for me to review. All I had to do was call to customer service and say make the switch, which I did. The lady who answered the phone was also super friendly and extremely helpful. I had a very pleasant experience ordering from etrailer. It was my first time ordering from them and I tell you it won't be my last. The customer service is personable, friendly, efficient and fast! The products are excellent as well with such a wide variety of quality items. To my surprise, I received my order in lightning speed. They shipped it out the same day! Thank you etrailer for a great experience!



by:

Very pleased with overall experience dealing with customer representative Wayne. Placed my order and asked a number of questions regarding the Thule rack that I wished to purchase. All questions were answered in a highly professional way. Received a quick delivery of product in 3 days although a 4 day window was given. Very happy with my purchase. Have not used the rack yet, but feel content that it was a good choice. Will get back to you in future after using rack, and hope to be able to give a good review along with some photo's. Thanks again, Wayne and E-Trailer.

Have been using the Thule Rhino Rack to transport my wife and grandchildrens bicycles over the past year and find product very easy to install and does just what it is intended to do very well. Keeps bikes stable and level while transporting. Good product. George E.

This was part of my third order from etrailer.com. We needed something to make carrying my wife's bike easier. Shipment arrived this morning along with the rack. This is extremely well made and should last a lone time. This makes carrying a girls bike really easy. Have already installed rack and bikes on RV and took it for a test drive. Perfect!!! Would recommend the adaptor bar over similar products I looked at locally.


Comments
After my last review we went on a 7000 mile RV trip through 9 states which lasted 27 days. The rack and bar were great. At night all we had to do was easily remove the bikes and lower the rack out of the way for access to RV storage if needed. I would periodically check the bikes and all were really secured. Getting ready for another trip 0f 5000 miles. Don’t have to worry about our bikes.I had previously purchased a hitch mounted motorcycle carrier which has been used on a3500 mile trip. Performed great. No problem in loading or unloading our scooter. Thanks for great products.

Adapter bar is made well, but I wish the telescoping section would have locking positions, otherwise it's good.



by:

A bit klunky, but does the job.



by:

Fir perfectly on our Electra Townie.



by:

My wife's bicycle is too small to be held firmly in the hitch rack. This adapter bar makes it workable and easier to lock with the other bike in the rack.



by:

Easy to use and fit my long wheelbase bikes just fine.



by:

Excellent customer service. Order was delivered quite expediently. I had to reach out to customer service (Ashley) and the issue was very easily and satisfactorily resolved.



by:

Excellent product, excellent customer service. I can't recommend earlier enough. 5 Stars!



by:

Great product- delivered quicker than expected, too.

Verg easy to use and very sturdy



by:

Really much better quality than I expec ted.

Ask the Experts about this Rhino Rack Accessories and Parts



  • What are the Seat Stem Dimensions of the Rhino-Rack Bike Frame Adapter Bar for Women's and Alt Frame
    The Rhino-Rack Bike Frame Adapter Bar # RRRBCA021 has a 2" diameter for the head stem (by the handle bars) and a 30mm measurement at the seat stem. Which translates to approximately 1.2" which can be represented as 1-1/5th". That measurement is large enough to fit the most commonly found seat stems.

  • Frame Adapter Bar Recommendation that is the Easiest to Use
    We have heard that the buttons of the Thule Bike Adapter bar part # TH982XT can be pretty difficult to press. A coworker of mine has this adapter and has reported the same thing. I wish there was a trick to it that would make it easier, but there isn't. Of all of the adapter bars we offer the easiest one to use by far is the Swagman Adapter Bar part # 64005. If you are frustrated enough to try a different adapter this would be the one to use. I attached a review video for you to check...

  • Will Bike Rack Anti-Sway Cradles be Compatible With Bike Frame Adapter Bar
    The anti-sway cradle will still work. The rubber strap for the anti sway strap can be attached at any place on the seat post down tube. Using a frame adapter bar won't affect that fit, as you can see in the photo I've provided. As far as frame adapters go, we really like the # 64005 from Swagman because it's the easiest to use adapter bar we offer.

    The adapter length range of the Rhino-Rack Bike Frame Adapter Bar for Women's and Alternative Frame Bikes # RRRBCA021 is 23-29 inches. Since you need 28-29 inches this would work well for you.

  • Is The RockyMount MonoRail Sturdy, Reliable and Are The Bikes Secure On The Highway
    The RockyMounts MonoRail Solo 1 Bike Platform Rack - 1-1/4" and 2" Hitches part # RKY10007 is very secure and one of our more popular wheel mount bike rack options for delicate carbon fiber bike frames. The arm ratchets down over the wheel to hold it in the cradle. It does include an anti-wobble threaded hitch pin to eliminate bike rack sway. I recommend to take a look for yourself at the video review I have posted demonstrating how the bike rack behaves on the road and even going over...

This adapter lets you carry a woman's bicycle on your dual-arm bike rack. The bar telescopes from 23" to 29" long.

  • Best Bike Rack For Two Electric Bikes Weighing 48 lbs
    The bike rack you need is the Swagman Current # S64678. It will fit in your 2" hitch, can hold up to 60lbs per bike, will work well with your 2014 Hyundai Santa Fe because of it's tilting feature. You will be able to tilt the rack away even with your Towne Style Electric Bike. You will need an adapter bar since it is an odd style frame. Grab two of the Swagman Adapter Bar # 64005 for both of your bikes as long as they are under 35 lbs. The adapter bar has a capacity of 35 lbs but this...

  • Will the Saris Freedom Bike Rack Work on a 2005 Mini Cooper?
    With a maximum per-bike weight limit of 60 pounds and frame-mount ratcheting hooks, the Saris Freedom Bike Rack for 2 Bikes # SA4412B will do the trick. Since you are mounting a cruiser-style bike, I recommend getting a Rhino-Rack Bike Frame Adapter Bar for Women's and Alternative Frame Bikes # RRRBCA021 that attaches to the bike's seat post and handlebar stem post so it can be secured by the ratcheting hooks.

  • Can Thule Passage Trunk Bike Rack Be Used With Lightweight Electric Bike On Prius?
    Trunk bike racks are not typically recommended for electric bikes due to weight capacity issues, however, it seems as though you may be able to reduce the weight of your ebike down to the 35lb capacity of the Thule Passage Trunk Bike Rack for 2 Bikes # TH910XT. If you are able to reduce the weight down to 35lbs then you will also need to use an adapter bar like # RRRBCA021 since it is a step through bike. I attached demonstration videos for you to check out.

  • How To Mount A Children's Bike On A Hanging Bike Rack With Frame Cradles
    Any hanging bike rack that uses frame-mount cradles, like the Thule Apex XT 2 Bike Rack # TH9024XT, will have a hard time securing an oddly-shaped bike frame such as children's bikes or step-thru bikes. In this case, you will want to add an adapter bar to grab onto the bike's seat post and handlebar stem instead of the frame. Rhino-Rack Bike Frame Adapter Bar # RRRBCA021 would work well and your bike will then be properly secured to the Thule Apex bike rack. While we do not have a video...

  • Trek Marlin 6 Bikes Fitment onto the Thule Gateway Pro 2 Bike Rack # TH88VR
    Yes! I confirmed with Thule that the Thule Gateway Pro 2 Bike Rack # TH88VR fits a 2019 Volkswagen Jetta. As far as the shape of the sharp slanted downtubes of your bikes, I recommend using a bike frame adapter bar # RRRBCA021 for each bike. This adapter bar will provide your bikes with a straight, horizontal plane that is required to attach to the arms of the rack. I went ahead and attached a video that shows how the adapter works with a bike frame similar to yours. As far as weight capacity,...

    We offer trailer hitches from Curt, Hidden Hitch, and Draw-Tite for the 2012 Toyota Venza. I have attached a link to all of our trailer hitches for your Venza. I recommend the Draw-Tite Class III Trailer Hitch # 75663. This hitch has a 2 inch hitch receiver, a towing capacity of 3,500 pounds, and a tongue weight capacity of 350 pounds. It is important to check your owner's manual for your vehicle's maximum towing capacity and tongue weight capacity before deciding what cargo you want to...

  • Is Adapter Bar Needed for Carrying Kids Bikes On Saris Glide EX 5 Rack
    I definitely recommend an adapter bar for hitch mounted, hanging style racks like the Saris Glide EX 5 bike rack (discontinued). Having done this myself for years with my own hanging style rack and no adapter bar with my 2 boy's bikes, I definitely wish I knew about these years ago. The Rhino-Rack Bike Frame Adapter Bar for Women's and Alternative Frame Bikes # RRRBCA021 is a great option. An adapter bar helps provide safe, level transport of a woman's, child's, or full-suspension...

  • Curt 2 Bike Platform C18085 and Malone RunWay 2-Bike MPG2149 Through Bike Compatibility
    Both the Curt 2 # C18085 and the Malone RunWay 2 # MPG2149 will work with a step through bike like yours but you will need to get an adapter bar like the Rhino-Rack Bike Frame Adapter Bar # RRRBCA021. This will just go in between your handle bars and your seat! Both are pretty much that same thing but if it were me, I would get the Curt 2 just because it can fold in half for better storage and/or to unblock tailights. I've included a video to help show you how they work!

    The Swagman Dispatch, part # S44FR, will work with your 2014 Nissan Rogue. This bike rack is compatible with the 2 x 2 inch receiver on your Class III trailer hitch. This bike rack is designed to be carried without a ball mount. I have attached a review video of this platform bike rack for you. If you plan on carrying bikes with alternative or step-though frames that lack a tradition top frame bar, I recommend using an adapter bar, like this one by Rhino-Rack # RRRBCA021. The adapter...

  • How To Carry Bikes While Towing a Boat Trailer
    I do have an option for you but I can't say I have ever heard of someone mounting a bike rack directly to the tongue of their trailer nor do I have an option for this. The best option to carry your bikes while towing is between the trailer and vehicle. This option will also allow for a much greater variety of bike racks to be used as well because they don't need to be rated for use on a trailer. In order to carry your bikes between the trailer and vehicle you will first need a dual ball...

  • Can Swagman XTC-2 TILT Bike Rack Travel on the Highway
    Traveling on the highway will not cause any issues whatsoever for the Swagman XTC-2 TILT 2-Bike Rack # S64671. There are no specific speed restrictions and the rack will stay secure in your hitch with its included pin and clip. I do recommend adding a lock to protect your investment, and it has the added benefit of being an anti-rattle device, the Locking Anti-Rattle, Threaded Hitch Pin for Swagman Hitch Racks # S64029.

This can be done, but there are some things to keep in mind. First, this ball mount has a 2" drop, so you will need to be sure this is acceptable for your trailer's coupler.

This is a really nice carrier which has an integrated cable lock to keep your bikes secured to the carrier and it also has a security strap to keep the carrier secured to your locked trunk. Anti-Sway cradles help to reduce any possible bike sway or bike contact while also absorbing vibration when traveling. Keep in mind you may need to use an adapter bar like # RRRBCA021 if you plan...

Since the Hollywood Racks Traveler 4 Bike Carrier # HR8500 measures 9-1/2" from the hitch pin hole, you will have plenty of clearance between your bumper and the bike rack's upright bar.

The option I recommend instead is from a similar high-quality manufacturer, Yakima: - Yakima HalfBack 2-Bike Rack - Trunk Mount # Y02636 I really like the HalfBack for a number of reasons, starting with its strong anti-sway cradles and ratcheting straps which secure your bikes at three different points.

    I have a great solution for you. Unfortunately, there are no accessories to modify the Inno Tire Hold 2 # INH120 in order to make it accommodate e-bikes with fenders. Here at etrailer, we do not recommend using bike racks with a wheel-mounting attachment style for bikes with fenders. The reason for this is because bike fenders can become cracked or damaged during transport.

This bike rack is designed well and is able to clear SUV spoilers, which your Lexus probably has. This carrier uses soft anti-sway cradles that prevent your bikes from moving around on those bumpy roads and also prevent your bike frame from getting scratched....

  • Can Swagman Dispatch 2-Bike Rack Carry A Step-Thru Bike Without Using An Adapter Bar?

While some customers have been able to use this bike rack to transport step-thru bikes without an adapter, the safest route is certainly to use an adapter bar such as # RRRBCA021 to ensure your bike is secured properly. Since you prefer not to use an adapter bar, I would look into the Thule EasyFold XT Bike Rack for 2 Electric Bikes - 1-1/4" and...
