  • 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...

  • What’s Difference between Swagman Frame Adapter # 63999 and # 64005
    Basically the two Swagman bike frame adapter bars part number # S57FR and the # 64005 are the same. Either would work just as well as the other. They both have the same width range.

  • 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.

  • 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...

  • Hitch Bike Rack That Allows An Electric Fat Bike To Be Hauled On A Jeep And A Winnebago Motorhome
    I know exactly what you need in order to haul your electric fat tire bike on your Winnebago motorhome and on the back of your 2018 Jeep Wrangler. You will need a bike rack that is compatible with motorhomes AND flat-towing. There are not any 1-bike carriers that will meet your needs so you will need to go with a 2-bike carrier. I recommend looking into the Swagman E-Spec Bike Rack for 2 Electric Bikes - 2" Hitches # S94FR. This bike rack has a weight capacity of 70lbs and can hold up...

  • 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 # LGA34FR. It can handle 2 bikes up to 75 pounds. It also uses a wheel-mount design so your alternative...

  • How Long Will it Take to Put On & Off Saris Bones EX 3-Bike Trunk Rack on 2020 VW Jetta
    It's difficult to give an exact time, and "quickly" can be pretty subjective in regards to putting on or removing the Saris rack you asked about: - Sairs Bones EX 3-Bike Rack - Trunk Mount # SA803 The first time you install it is going to be quite a bit longer, maybe 10-15 minutes or so. But once you get used to exactly what you have to do to install it on your 2020 Volkswagen Jetta, it will take very little time, maybe a few minutes or less as you'll know precisely where the straps...

  • Recommended Bike Rack For Carrying 2 e-Bikes On The Back Of A Travel Trailer
    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. With the way that it clamps to a bike though, you will need an adapter bar for your step through bikes. The correct adapter bar will depend on how long you need it to be, but the Swagman Bike Frame Adapter Bar # S57FR,...

  • Will the Thule T2 Pro XTR Work with Two Electric Bikes with Fenders on My 2022 Acura MDX?
    I have a solution for you. Here at etrailer, we highly discourage using a wheel-mount bike rack like the Thule T2 Pro XTR Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount # TH83JV when using bikes with fenders. The wheel mounts increase the possibility for cracking and damage of the fenders. With that being said, a great alternative hitch bike rack is one that uses a frame-mount style. I recommend the Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Bikes - 2" Hitches - Frame...

  • 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.

  • Recommended Bike Rack for Fifth Wheel
    It takes a special kind of bike rack to be approved for mounting on a 5th wheel. The suspension on RVs, motorhomes, and 5th wheelers are different compared to a car. Also, there is more road stress, bounce, and sway on the back of these vehicles. Bike racks need to be designed to handle this road stress to be approved for 5th wheel applications, which the Yakima HoldUp # Y02443 unfortunately is not. My favorite recommendation for RVs and fifth wheels is the Swagman E-Spec # S94FR. This...

  • Adapter Needed For Alternative Frame Bikes On A Thule DoubleTrack Pro XT Bike Rack
    To lock down your wife's step through frame bike on the Thule DoubleTrack Pro XT Bike Rack # TH92BJ you'll just need an adapter like the Swagman Bike Frame Adapter Bar for Electric, Step Through, and Cruiser Bikes Item # S57FR. The quick-release hooks clamp around your bike's seat post and handlebar's stem post so that the ratcheting hooks have something to grip onto.

  • Which Trailer Hitch Receiver Will Not Require Fascia Bumper Trimming For My 2020 Honda CR-V?
    The Etrailer Trailer Hitch Receiver Matte Black Finish - Class III - 2" # e98848 does not have an installation video available at this time, although I did attach an installation video for a similar hitch that has essentially the same installation process. The Etrailer hitch receiver has a max towing capacity if 3,500lbs and max tongue weight of 525lbs. It does require trimming of the lower fascia trim in order to give a sleek look where only the 2" receiver is showing at the back of your...

  • Recommended Bike Frame Adapter Bar for Swagman Current and Trek Verve 2 Lowstep
    To pair with the Swagman Current # S64678 I recommend using the SportRack Bike Frame Adapter Bar for Women's and Alternative Frame Bikes # SR0500, which will fit well on your Trek Verve 2 Lowstep. These are meant to work as universal parts though, so really any adapter bar would work, no matter who the manufacturer is. I've linked a short review video that shows how this is installed.

  • Hitch Mounted Bike Rack For Two RadCity ST3 's On A 2016 Honda HR-V
    The Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Cargo Bikes # HR1450Z-W is the ideal option due to their ability to carry up to 80lbs per bike. The Swagman Current Bike Rack for 2 Electric Bikes # S64678 would work great as an alternative for your two RadCity ST3 bikes. If you remove the 7lbs batteries from the bikes you will be at 116lbs and would put your bikes 4 pounds under the maximum rating for this rack. Additionally you will need to use the Swagman Bike Frame...

  • What is the Best E-Bike Rack for an RV and a Toyota Highlander?
    The Swagman E-Spec Bike Rack for 2 Electric Bikes - 2" # S94FR is the perfect rack for both RVs and your Toyota Highlander. It has the construction that will stand against the added torque when mounted with bikes at the end of your RV. It also has a high maximum per-bike weight capacity of 70 pounds. The Fat Tire Adapter Kit for Swagman G10 and E-Spec Bike Racks # S64679 will allow you to attach fat-tire bikes. For the step-through bike, I recommend the Swagman Bike Frame Adapter Bar...

  • Will the Kuat Transfer V2 Work with 2 Townie Bikes with Baskets?
    As far as the male townie with the basket, the ratcheting hooks of the Kuat Transfer V2 Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount # KU84FR will be able to bypass the basket and attach on the wheel. As for the female townie, from the looks of the picture, it is possible to have the ratcheting hook rest against the basket mount, but there would be danger of damage to the basket mount due to bumps and extra torque while the vehicle is in motion. One solution to this issue is removing...

  • 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.

  • Recommended Hitch Mounted Bike Rack For 76lb E-Bike With 53 Wheel Base
    Since your Radwagon Electric Bike with a 53" wheel base weighs in at just over 76lbs I recommend the Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # HLY84FR which has a weight capacity of 80lbs per bike and works with wheelbases up to 60". Since your E-bike has a alternative frame style you will need to use Adapter # S57FR if from the seat post to the handle bars is 25" - 31", or the # SA3040 if this distance is 19" - 25".

  • Will the Kuat Transfer V2 Bike Rack for 2 Bikes Work with Electric Bikes with Fenders?
    I have a solution for you. Here at etrailer, we highly discourage the use of wheel-mount style bike racks when transporting bikes with fenders. With that being said, even if the front wheel of your Macwheel did safely attach to the Kuat Transfer V2 Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount # KU84FR, the rear wheel fender would interfere with the rack. For a solution to this problem, I recommend the Swagman E-Spec Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # S94FR....

  • 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...

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...

  • 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...

    With a bike as heavy as 72 pounds, we only have two options able to carry that much. The first is the Hollywood Racks Sport Rider Se, part # HLY84FR. It's a platform-style, frame-mount rack capable of holding 2 bikes up to 80 pounds each. I've linked to a video review of this below. The second is the Lets Go Aero V-Lectric PRO, part # LGA77FR. This one's a hanging-style, wheel-mount rack capable of holding 2 bikes up to 75 pounds each. Neither of these have plate holders or lights,...

If this is what you have, then there is no safe way to transport your 71lb RadRover ST Ebikes with this bike rack. If you actually have a different model that has a 60lb per bike capacity like you mentioned, then you could try removing the batteries from your ebikes to reduce the overall weight of the bikes and you may...

    I have a great solution for transporting up to 4 bikes. I did some research on your 2019 Subaru Crosstrek, and the manufacturer recommends not to exceed a tongue weight of 150 pounds on your vehicle. The Swagman Quad 2+2 rack has a carrier weight of 86 pounds, which is high considering you need to account for the added weight of four bikes. With removing 2 of the positions, I confirmed with Swagman that the Quad 2 + 2 weighs 50 pounds. For a solution to this problem, I recommend the...

  • 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.

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....
