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.

works perfect

great add-on for my son 20" fat tire ebike.

Works great

Works great in configuring the rack to carry a 20"x4" fat tire, foldable ebike. Sturdy metal, with a good rust preventative coating, and an easy clamshell design to attach it to the bike rack.

Take up the slack

When I purchased a new bike for my wife with 20” wheels the wheel hoops were too big to hold the wheel high enough to prevent it from hitting the derailleur. My first solution was to use a section of a pool noodle in the front and rear to take up the space to raise the wheel. It worked but looked pretty tacky. I purchased a small wheel adapter and it worked like a charm. It’s not nearly as colorful as the lime green pool noodle and duct tape.
