Bike Frame Adapter Bar

Swagman Deluxe Adapter Bar Easy InstallationSwagman Deluxe Adapter Bar Easy Installation

This adapter bar allows you to carry a bike with a sloping top tube or step-through frame on your bike rack. It fits between the seat post and handlebar stem post of your bike to ensure level transport on your hanging-style bike rack. It also creates a top tube so you can carry your bike on frame-mount platform-style rack. The spring-loaded bar telescopes to fit multiple frame sizes, and it can be used with no-rise bike stems.


Easy Installation

Swagman Deluxe Adapter Bar Vinyl Collars

To install the adapter bar simply open the hooks with the integrated release buttons, wrap one hook around your handlebar stem post and the other around your seat post, and close the hooks. The hooks open outward - parallel with the bar - to help you avoid interference from the seat and handlebars during installation. The bar has red "Up" indicators on each end to help prevent incorrect installation. The hooks have a vinyl coating that won't scratch or scuff your bikes' paint.

The adapter bar is probably fine if you have to have it-the quality of the part seems fine. Don’t buy it from etrailer though if you think you might need to return it. Unlike [online stores], they don’t accept returns on bike racks if you have assembled the rack, so they may well have the same policy for this adapter. I bought the HR1500 bike rack with these adapter bars, but the right solution would have been the HR1700. They won’t allow exchanges or returns.




by:

Works as advertised. We have two different types of Fat Tire Ebikes and both are step thru style. Perfect for putting on and clamping them down on the bike rack for travel. Great accessory.




by:

I would advise anyone if they are considering ordering anything from etrailer to make sure it's what you want because if you have to return it you have to pay for shipping and what is left you will be waiting for a long time before you get it back! be careful!




by:

These fit perfectly on our Lectric eBikes and helped ensure they are secure to our swagman eBike approved bike rack.




by:

I've needed this bar adapter for my trek ebike "step-through" for my particular bike rack which hooks onto the bikes. It has worked just fine in providing a way for the bike to be secured onto the rack.




by:

Works great with the Swagman E-Spec Bike Rack and the step through Letric bike.




by:

I used it once to transport my wife’s bike in for service and it chipped the paint on the bars of the bike. Need some sort of rubber protectors at each end to protect the bike.




by:

Been using it quite a bit and am happy with the e bike rack. Very well built and functional.




by:

This bar is quick and easy to use. It has flexibility to fit any bike and is plenty strong. It allows us to attach our step through bikes to our rack. Very happy with the purchase.




by:

Seems to be too long for my Heybike cityscape but we seem to have it secured to the rack.




by:

I bought this item but found something more suitable for my specific application. Called to return and Nicole was great. No hassle return. Will continue to shop with etrailer in the future.




by:

This is a great all around product that allows almost any bike to adapt to the bike rack.




by:

Good design, decent quality. Very satis fied




by:

Good equipment




by:

Good quality and heavy duty allowing us to load two E-bikes.




by:

This is a better bar than the cheap one I bought prior to this purchase, but this bar has poor figment and the jury is out on how long it will last.




by:

The bar was easy to install and worked exactly as it was designed. Our bikes will be quite stable on our bike rack.




by:

Works well




by:

Speed and service excellent. Box came a bit banged up but no damage to item so very happy with etrailer.




by:

Great well made product!

  • How Do I Secure a Women's Bike or an Alternate-Frame Style Electric Bike to My Bike Rack?
    The best solution is to purchase the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes # S57FR for the non-electric women's bike and any electric bike that has a step-through or alternative frame. The adapter bar will give you a straight horizontal plane to attach and secure your bike to the bike rack. It must be noted that some bike racks do not require bike frame adapter bars because the attaching points are more versatile. If you want me to confirm if your...

  • Will the Swagman Bike Frame Adapter Bar # S57FR Work With my Trek Verve 2 Electric Step Thru Bikes
    The adjustable clamp on the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes # S57FR measures from 25" to 31". I spoke to a representative at Verve Bikes and he felt, without knowing the exact models you have, that most of the Verve 2 bikes would fit that bar.

  • Will the Swagman E-Spec Bike Rack Work With Two Step-Through Frame Bikes
    The Swagman E-Spec Bike Rack part # S94FR can usually accommodate one step-through frame bike without needing an adapter by switching the small and long hook around but for two step-through frame bikes I do recommend as least one adapter, the Swagman Bike Frame Adapter Bar part # S57FR.

  • E-Bike Rack Recommendation for Use on Travel Trailer and Ford F-250
    Thank you for the info! The only bike rack capable of what you're needing is the Swagman E-Spec Bike Rack # S94FR which is rated for use on a travel trailer and can carry up to 70 lb bikes - so you'll definitely need to remove your batteries prior to loading up. This rack secures bikes by a ratcheting hook that comes down over the frame which is a great solution since a lot of e-bikes come with front and rear fenders as well as step-thru frames. You might also need the Swagman Bike Frame...

  • Is There a Solution for Securing a Step-Thru Bike to a Swagman Current Bike Rack?
    The ratcheting hooks on the Swagman Current # S64678 can slide up and down the post of the rack to accommodate most alternative bike frames styles. For a guaranteed mounting point on your step-thru bike, you can purchase the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes # S57FR. The adapter bar creates a straight mounting point so that the Current can secure the bike by the frame. The quick-release hooks clamp around your bike's seat post and handlebar's stem...

  • Will the Swagman Current Bike Rack for 2 Electric Bikes Work With Step-Through Frames
    The Swagman Current Bike Rack for 2 Electric Bikes part # S64678 is a great bike rack option and it can be used on bikes with a step-through frame. The hooks can be adjusted but there are some instances in which the hooks won't be able to reach the bottom, this is usually an issue when used with two step-through frames. Therefore, I recommend switching the long and small hook around then using an adapter bar, the Swagman Bike Frame Adapter Bar part # S57FR.

    You can use a step-through bike with the Swagman Chinook Bike Rack for 2 Bikes - 1-1/4" and 2" Hitches - Frame Mount # S64683 with the help of the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes # S57FR.

  • Does Rear Bumper Fascia On 2021 Lexus RX 350 Need To Be Trimmed For Draw-Tite Trailer Hitch 75540?
    The Draw-Tite Trailer Hitch Receiver # 75540 you were looking at for your 2021 Lexus RX 350 is indeed confirmed to fit your vehicle, but it does require trimming of the rear bumper fascia as you can see in the included diagram. It is pretty common for hitches to require some trimming , and in this case the trimming of the bumper will be completely hidden by the trailer hitch receiver. Moving on to the component for your bike, it sounds like you are looking for an adapter bar. The correct...

  • Best 5th Wheel E-Bike Carrier for Rad City and Rad Rover Fat Tire E-Bikes
    The Swagman E-Spec # S94FR is rated for carrying bikes on the back of a 5th wheel, so it's the perfect solution for you to carry your Rad City and Rad Rover e-bikes. Because this rack is setup to carry standard size tires no larger than 3" wide, you can adapt this rack to carry fat tire bikes using the Fat Tire Adapter Kit for Swagman Racks # S64679. Lastly, as you've noticed, you're also going to likely need the Swagman Bike Frame Adapter Bar # S57FR. With all of those parts you're going...

  • Recommended Bike Rack For Two Electric Bikes With Fenders
    I would be happy to recommend a bike rack for your two Aventon electric bikes. Since both of your electric bikes have fenders I recommend the Swagman E-Spec Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # S94FR which will accommodate bikes weighing up to 70lbs each with tires up 3" wide. Since one of your bikes has a step through frame you will also need the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes # S57FR which will give the padded frame...

  • Recommended Platform 2-Bike Rack For 1 Electric Fat Tire Bike And 1 Regular Bike
    I highly recommend going with the Swagman E-Spec Bike Rack # S94FR. This is a platform bike rack and fits 2" hitches. This bike rack is specifically made to carry 2 electric bikes, but will also work very well with regular non-electric bikes. It is a frame-mount so you don't have to worry about fenders or baskets interfering with anything. The wheel trays can hold tires up to 3" wide, but you can add fat bike kit # S64679 which can hold tires up to 5" wide. The weight capacity is 70lbs...

  • Recommended Bike Rack For Hauling 2 Electric Fat Bikes On A Travel Trailer Or Motorhome
    The Swagman E-Spec Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # S94FR is definitely the bike rack I recommend for you. It is compatible with travel trailers since it is built to withstand the excess bouncing that occurs on the back of a travel trailer or motorhome. This bike rack comes with locks to secure the bikes to the carrier, along with anti-rattle hitch pin to secure the bike rack to the trailer hitch receiver. The Swagman E-Spec is rated at 70lbs per bike which is...

  • What Bike Rack do You Recommend for 2 Electra Path 9D Step-Through Bikes?
    For a bike rack that fits your 2-inch trailer hitch on your 2021 Acura RDX that fits your 2 Electra Path 9D bikes, I recommend the Swagman Trailhead 2 Bike Rack for 1-1/4" and 2" Hitches - Tilting # S63360. The Trailhead has a 35 pound per-bike weight capacity and will allow you to tilt the rack (with bikes unloaded) to gain better access to your vehicle's rear hatch. Since this rack does not come with any locks you may want to also add the Anti-Rattle Hitch Lock and Cable for Swagman Bike...

  • Yakima OnRamp Bike Rack Frame Clamp Maneuverability
    The Yakima OnRamp Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # Y36FR is versatile enough to move up and down and rotate enough to mount to the frame of your Pedego Interceptor ebike. You may not get as tight of a grip on the frame though so I do recommend using a bike frame adapter like the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes Item # S57FR.

  • E-Bike Hitch Platform Bike Rack Recommendation for A Motorhome
    The Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Bikes - 1-1/4" and 2" Hitches, part # HLY74FR, is a great choice. It can carry bikes up to 80 lbs. Your 5" tires will not be a problem either. It comes with an anti-rattle hitch pin to reduce movement between the hitch receiver and the bike rack. The tilt down mast works with bikes on the rack and when it is empty, so you will always have access to the rear of your RV. You can lock the rack to your RV and your bikes to the rack....

    The only thing you should need for your Hollywood Racks RV Rider Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # HLY64FR to be compatible with your RadRunner E-bikes is the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes # S57FR. You'll be able to attach this to your bike's frame so the clamps have something to grab onto to hold the bike down.

  • Will the Swagman Bike Frame Adapter Bar Support a 65-LB Bike
    The Swagman Bike Frame Adapter Bar, part # S57FR, has a weight capacity of 35 pounds. It will not work with your 65-pound bike. In fact, there are no adapter bars that can handle that much weight. As such, a hanging-style bike rack will not be an option for your bike. Your only option to carry your heavy bike is to use a different rack like the Lets Go Aero V-Lectric Bike Rack, part # LGA77FR. It can handle 2 bikes up to 75 pounds. It also uses a wheel-mount design so your alternative...

    The Yakima OnRamp Bike Rack # Y36FR will be an excellent rack for carrying your e-Bikes on the back of your travel trailer. This rack is rated for use with standard vehicles, travel trailers, motor homes, flat towed vehicles, and 5th wheels, so it is highly versatile, but I do need to mention that using it on anything other than a standard vehicle will have the weight limit per bike reduced to 40 pounds.

You'll need to start off by adding a hitch receiver to your bumper and for that I recommend the Mount-n-Lock HiLoHitch for 4" RV Bumpers # MNT47FR which gives you a 2" receiver with a 300 lb weight rating. Then for a bike rack I recommend the Swagman E-Spec Bike Rack # S94FR which has been rated for use at the back of a trailer (not all bike racks have this rating) and can hold up to 70 lb bikes.

In addition, the SingleSpeed includes a wheel-mount attachment style, which will potentially cause cracking or damage to your fenders during transport on your 2020 Lincoln Aviator.
