Small Wheel Adapter for Universal Wheel Holders

Sku: HR1450Z-E-F1


Small Wheel Adapter for Universal Wheel Holders 

  • QTY 1
  • For use with 20" Fat Tire rear wheels to prevent derailleur hanger interference (You will only need one per bike- Use on rear wheel only)  
  • Can also be used for 16" - 20" kids bikes (You will need two per bike)
  • Can only be used on Universal Wheel Holders and previous Fat Tire Wheel Holders
  • Fits 5" wide wheel holder only

Do not use with any 24" - 29"/700c diameter wheel bikes. Doing so will void the warranty.

Please note: The Small Wheel Adapter is for the rear wheel only of a 20" fat tire bike, to prevent derailleur hanger interference. But, 20" fat tires can be mounted without the adapter, you just need to shift the rear derailleur into the lowest gear (the largest cog in the back) before you put your bike on the rack, doing so will pull the derailleur towards the rear wheel, i.e. away from the wheel holder cradle and therefore the adapter would not be necessary. But, you would have to do that every time you load that bicycle which is why most people end up using the Small Wheel Adapter.



Hollywood Racks started in 1973 when we began making trunk-mounted racks in the back of our bike shop in Hollywood, California. Our aim was simple: We wanted to make good quality products that were easy to use and came fully assembled. We earned a great reputation fast and soon began selling our racks to other bike shops throughout California.

Excellent Service

I ordered this same part from a competitor last June and was told each month it would be shipped the 25th of the next month. Finally I cancelled the order in December and ordered with Hollywood Racks and in 7 days I had my part. Thank you Hollywood Racks, now I know where to order from

Small wheel Adapter for Universal wheel holder

These brackets are PERFECT for solving the problem of 20 inch fat tires going into the universal wheel holders!!

Worth the wait

Such a simple design and yet provides the greatest value when loading heavy e-bikes. I’ve been waiting for this product for months, but it was worth the wait.

Susie Bottjer
20 inch wheel adapter

I had to order this part because my rack did not come with it. It is too bad that I had to pay for it
