DIY Hitch Mounted Vertical Bike Rack/ Cargo Carrier that Does Not Interfere with the Rear Spare Tire


Adding a hitch mounted bike carrier has been a problem on RT’s that are equipped with rear mounted spare tire carrier. I’ve seen many attempts by RT owners to negate this problem, from using hitch extenders to experimenting with different available bike carriers on the market. Clearing the spare tire is only half of the problem. Opening the Sprinter rear doors and lowering the spare tire with a hitch bike carrier mounted either with bikes loaded or unloaded is another huge problem not to mention the added length to the vehicle with the addition of hitch extender.


 I’ve fabricated a bolt-on hitch receiver that mounts to the passenger side of the factory hitch arm from this POST. Next on my built is a swing away adapter similar to Kuat Pivot design but with shorter swing arm and more compact design. The bike rack is a vertical design similar to Softride Hang2 but does not tilt down.

The smallest Rakattach swing adapter is about 26" long, I need about 18" long, so Rakattach won't work. The Softride Hang2 due to its tilting design is bulky and sticks out about 26 inches from rear door, my built only sticks out 14” that is 4” shorter than the spare tire carrier.  So the built goes...


Fabricating the swing adapter is pretty straight forward, starts with the plan, then just a matter of cutting, grinding and welding the parts together. The adapter cost me less than $60 to built, that does not include paint and tool consumables like grind wheels, welding wire and gas, etc. Parts needed (Amazon links)
Update:
If you are not into DIY, consider the new Rockymounts Backstage Swing -Away Platform Hitch Bike Rack, it swings out 180 degrees to facilitate opening of the rear doors. Based on the bike rack specs (link here), your RV (depending on make/ model) might still need a hitch extender to clear the spare tire. Check out these pictures of the Rockymounts Backstage mounted on a Sprinter Van: Click here.

Back to the project...the finished hitch swing adapter in locked closed position. I cut the Toggle Clamp locking handle about an inch shorter because it interferes with the rear door opening then Plasti Dip the handle red for OEM look.

Swing out position, about 55ยบ open and locked using the hitch pin. I can use either the cargo carrier or the bike carrier using this swing-away adapter.

Next is to fabricate the bike carrier itself. Purchasing a Hang2 bike rack and mounting it on my swing adapter would be the easier approach, but as I mentioned above, the Hang2 sticks out too much and it's too bulky. 


Here is one of the fabricated handlebar hooks. It is similar to the Hang2 design. I painted it black and used a 1/2" OD clear vinyl tubing (not shown) sleeves on the hooks to protect the bike handlebars from scratches.

The lower piece that goes into the hitch receiver. Right of photo is one of the upper tube pivot plate support.

More fabricated parts painted flat black. I'm too cheap to have them powder coated.

And here is the completed vertical bike hitch carrier (folded position) with "Yakima" die cut vinyl sticker for OEM look.
 
In folded position, the carrier sticks out about 14" from rear door.

And finally, the Kevlar reinforced security cable to secure the bikes, it also prevents the front wheels from spinning while underway. Maybe it's not the ultimate bike carrier built, but close I suppose.

Here is a short clip of our maiden voyage with the custom-made bike rack. Disregard the green towel wrapped around the handlebar in the video, I just put it there to protect the newly painted bike rack just in case, but it turned out not needed after all. The bike rack is very stable while underway, during abrupt turning, and braking...it did perform flawlessly.

  1. Outstanding & creative build. Any chance you would like to build an extra for sale?

    1. Thanks for the compliment. Also sorry that I cannot build and sell one to the public for liability reason hope you understand. I'm sure you can find a licensed fabricator that can copy the design, good luck and happy trekking!

    2. ingenious, now just need a swingaway storage bin as well

  2. Love your swing design, do you have a diagram for the swing built and all the parts needed, I saw your part lists, but that does not include the tubes itself I think, if you have a diagram, that will be great, so I can go to the welding shop and ask them to build one for me! :)

    1. Thanks. I'll make a diagram with measurements when I get the chance.

    2. Hey Any chance for a diagram as well for me? Thanks for all your ideas.

    3. Hi there, im banging my head against the wall working through a solution as well. I like yours and was wondering if you could share your diagrams for it? Am thinking to modify and make two cargo units, that swing each way. Thank you so much in advance!

    1. The bike handlebar hooks/bracket were fabricated using 1/2 inch steel rod and angle bar. I tried a smaller diameter (so you can reshape it by trial n error) steel rod first to bend it to a desired shape, then copy the final shape to the bigger rod before welding it permanently to the angle bar piece.

    2. You definitely need a bender to make the hooks.

  4. Our Class B will come w/ a bike rack, but no spare tire. Ideas on where to add/store a tire? Thanks

    1. You have many options, the tire will fit under the sofa bed if you prefer to store it inside Or you can mount it on the driver side rear door (see Owl Vans and Agile Offroad), or you can get the Factory RT hitch tire carrier, it is a bolt on carrier on the hitch arm (driver side). If you decide to mount it outside, make sure your bike carrier has enough clearance to fit the tire. Many use a hitch extension to clear the tire carrier.

  5. I came across this while looking for ideas on swingouts for my bike rack. Can you give any more details on the pivot used in your design? Is it just a bolt with a double shear mount? Any bushing in the moving part?

    1. Sorry for the late reply, your comment was buried into my spam folder. Blogspot comment moderation notification is awful.

      On the pivot, It is just a through bolt on a double shear mount, yes. The swing arms pivot holes are supported inside with a piece of round tube with ID same of the bolt size, this prevents compression of swing arm walls when the pivot bolt is torqued down. Hope that helps.

  6. Hey I used Lolo Racks hooks to make a ladder mounted bike rack on my van. Worked out great!
