Today we're taking a look at a replacement bike adapter ezHitch cup. This unit replaces the axle mounted ezHitch socket for your Thule Coaster XT bike, trailer, and stroller. It works with trailer and stroller part number TH10101803 00:00:15. It is a direct replacement from the original manufacturer. It's made from a durable steel construction and it features a nice protective finish to keep it safe from rust and corrosion. That's going to do it for today's look at the replacement bike adapter ezHitch cup..
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!
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!
Part arrived in good time. New and as described. Bought 2 so that we can tow our Chariot with 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
Perfect fit! Now my wife and I each have an adapter for our bike trailer.
Worked perfect
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.
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.

Thanks To etrailer

Very fine
A must have for Thule trailers like the Chariot. Having extras makes swapping bikes a lot easier. Get one (or two!)
My experience was great and the Thule bike trailer hitch I purchased works great
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.
The hitch adapter works perfectly with the previously purchased Thule axle. Fast shipping and great follow up by etrailer.
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.
Works perfectly. I wanted a second hitch cup so I could easily use the trailer with 2 different bikes.
Worked out great for my Thule chariot bike trailer!! And it was waaaay cheaper!!
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.
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.
Needed a 2nd one of these so I could setup a 2nd bike instead of having to switch the adapter back and forth.
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
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.
On-time delivery. Fits our cougar chariot 2 trailer. Easy installation on my bike!I just had a normal thru-axle.
They had a rare part I couldn't find anywhere at a reasonable price, except etrailer. Thanks!
A perfect fit/replacement hitch for my Nashbar branded double-seated bicycle trailer.
Great service from etrailer. The hitch works perfect!
