Replaces the axle-mounted ezHitch cup for your Thule bike trailer and stroller.


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!



I use it daily. It’s great.


It’s exactly what I needed and was sent to me quickly! That’s important because I live in Alaska and nothing ever gets up here quickly.


Works perfectly. I wanted a second hitch cup so I could easily use the trailer with 2 different bikes.


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


Great product, arrived on time and as expected. No surprises working with e-trailer. They are the best of the best.


Exactly what I needed.


Perfect fit! Now my wife and I each have an adapter for our bike trailer.


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 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.


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.



Fantastic. We actually bought a second!


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.


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


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


Just had To enlarge the hole slightly To fit the hub on my electric bike.
I Don't understand why thule dont sell this part alone in Canada.
Thanks To etrailer



Very fine


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


Worked perfect. Enough said.


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


Excellent. Fit onto my bike. And is so helpful so me and my husband can switch wh's carrying the trailer.


Got this as a second for our chariot so we didn’t have to switch it between my wife and I’d bikes. Works just like the one that came with the chariot.


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.


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


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.


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


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


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


Exactly as described-- official part from Thule. Works as expected. Product was in backorder but was delivered soon enough. Thanks for the great service!
