Prompt shipping saved the day, thanks.

by: Samuel 07/22/2020

Thule trailer hitch was exactly what I needed, and etrailer was the ONLY shop I could find that had it in stock. Great pricing, excellent customer service. Now my little guy can join me on my bike rides again!

Exact fit and product needed to attach my daughter’s trailer to my wife’s Aventon Lvl.2 e-bike

by: Paul T. 10/14/2019

Worked for a chariot carriers caddie tct circa 2004 we've had. I didn't want to swap the hitch from bike to bike and this hitch cup works great. Thank you

I bought a used Thule bike trailer and the adapter for my bike was missing. I couldn’t find it anywhere for less than $60 online until I stumbled upon etrailer.com. I paid less than $15 for the piece and shipping! I received updates about my order throughout the process. I have been very impressed by their customer service and attention to detail. Thanks for saving me money and keeping me posted!

1 year later still loving this product! Great quality and so easy to hookup and unhook the bike trailer.

by: DS 09/29/2024 One Year Later

Still works great hauling the chariot around behind my old Raleigh mtb. Sturdy piece, little sign of wear.

Still great after lots of use, likely to outlast the chariot itself!

by: Nicholas 07/03/2019

I received an older Chariot as a gift and I just needed the ball hitch. It fit perfect! Also, great communication via E-mail from the etrailer team with order confirmation, shipping updates, and follow up.

Very fine

by: Jeff 06/19/2022

The piece was exactly what I needed. Now I don’t have to remove the quick release on my bike, if my partner wants to tow our son. Fast and friendly service from etrailer, transparent and informative.

by: SWITTY 01/07/2021 One Year Later

Just as good as the original. Bought a chariot, but we have too many bikes. Having a couple extra of these makes it easy to broaden your options. These are the most affordable that I found, by far. I actually drilled one a bit bigger to fit my MTB thru-axle, and ended up purchasing a slightly longer axel - but it was worth it, now I can use my nice MTB to haul the kiddo.

by: Vincent 03/23/2022 One Year Later

My experience was great and the Thule bike trailer hitch I purchased works great

by: Gabe 04/01/2022 One Year Later

A must have for Thule trailers like the Chariot. Having extras makes swapping bikes a lot easier. Get one (or two!)

by: Michel 05/28/2022 One Year Later

Worked out great for my Thule chariot bike trailer!! And it was waaaay cheaper!!

by: Hector 01/20/2022

The hitch adapter works perfectly with the previously purchased Thule axle. Fast shipping and great follow up by etrailer.

by: Alissa 05/12/2021 One Year Later

Bought this to put on our second bike so I wasn’t the only one pulling the double thule trailer. It fits exactly like the one that came with our trailer and we haven’t had a single problem.

by: Chris 04/09/2021 One Year Later

Needed a 2nd one of these so I could setup a 2nd bike instead of having to switch the adapter back and forth.

by: Laurence 06/28/2025

Part arrived in good time. New and as described. Bought 2 so that we can tow our Chariot with different bikes.

by: Cameron 05/16/2020

Thank you! Usps broke the package and lost the hitch, BUT etrailer immediately shipped us a new one without charge! It came right away. Great customer service.

by: Eric 04/25/2022 One Year Later

Works as advertised. High quality metal hitch. I bought it to replace the one that was on my bike that was stolen.

by: Sandra 10/09/2019

we bought a used Chariot Carrier for our baby and just needed this piece to hitch it to our bike. it arrived extremely quickly and worked perfectly.

by: Bruce 08/05/2022

Pretty straight forward as it is a replacement part. But ordering/shipping was easy and prompt. Beats running around trying to find it at a local bike shop and having them end up ordering it

by: Luis 07/22/2020

Great product. Needed an extra for an additional bike. This makes it easier than removing it and installing every time. Shipping took forever but eventually received it.

by: Matthew 07/01/2019

Couldn’t find these anywhere else as a stand alone part. Good price for extras. Now I don’t have to move the 1 hitch to multiple different bikes.

by: David J 03/29/2020 One Year Later

Bought a couple to make all bikes in the family compatible with our Thule Chariot Cougar2.

Availability of Replacement Wheel/Tire and Bike Connection for Thule Stroller
I'm guessing you're needing a replacement stroller wheel and the parts used to connect it to the bike, is that right? If you have the Chariot, Cheetah or Cougar stroller, you'd need wheel # TH40102421 or for the Coaster stroller, use # 40192431. The strollers mount to the bike using a skewer mounted bracket like the once you referenced, part # TH20100796. That skewer mount works for the following stroller models: 2011 and newer Cheetah 1-child and 2-child bike trailers 2011 and newer...

How To Determine Which Ball Mount To Choose
We have a very wide variety of ball mounts to choose from. Finding the correct one will depend on a few things though. First you will need to know the distance from the ground to the top of the inside of the trailer hitch once installed. Next, you will then need to measure from the ground to the bottom of the trailer coupler when on as even a surface as possible. The difference will tell you how much drop or rise you will need. As an example, if the trailer hitch measures 12" and the...

In most cases, yes; the Replacement Bike Adapter ezHitch Cup for Thule Bike Trailer and Stroller # 50103033 will be all that you need to connect your bike trailer/stroller to the quick release skewer on your bike without any other parts needed. However, if you've got a specialized hub like an Internally Geared SRAM Spectro or Internally Geared Shimano Hub, you would need a different part. If you've got one of these specialized hubs on your bikes, I've linked the parts we have available...
