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 great for the RAD MINI.

Easy to put on and is a must for smaller tires on the rack that I have.

David Medack
Great service.

My bike rack came without small wheel adapters.Sent an email to Hollywood Racks asking if I could get some. Received a response back in less than hour saying they would send them. In 3 hrs. time I got a message it was shipped. Best service I ever experienced.

Work as expected - prevents the derailleur from hitting on the rack

Michael Van Fleet
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.
