The "Croozer" brand has made a name for itself as a leading manufacturer of high-quality bicycle trailers. However, before these versatile bicycle trailers can be used, they must first be securely connected to the bicycle. And this is exactly where we at Trailer Components come into play. Here you will not only find lots of universal bicycle trailer couplings/adapters and spare parts, but also the best Croozer bicycle trailer couplings and adapters. And now you can find out how to attach your new Croozer bike trailer.
Attaching the Croozer to the bike: how it works
As the popular Croozer bike trailers can be attached in different ways, we have many different components available. Our range extends from couplings and adapters with quick-release axles for "Croozer" brand bicycle trailers to so-called solid axle couplings and adapters. But how exactly can these components be attached and what do the terms "solid axle, quick release and thru axle mean? This refers to the different mounting options. Because the Croozer bicycle trailer coupling / adapter can be fitted either via:
- The solid axle on the wheel
- The thru axle on the wheel
- Or the quick release on the bike
We will explain exactly how to attach a Croozer bike trailer coupling in the following lines. And if you are not sure which Croozer bike trailer coupling or adapter you need, you can contact our customer service team at any time. We are here to help and advise you so that you too can find the perfect coupling/adapter for your bike trailer.

Option 1: Solid axle
If the rear wheel of your bike is attached with a solid axle, you can normally attach your Croozer bike trailer to the bike with the universal coupling included in the scope of delivery. However, if you are looking for a more robust or even more elegant solution, we recommend you take a look at our numerous special solid axle couplings or solid axle adapters.
Option 2: Quick release
You can also normally use the axle clutch included in the scope of delivery if your rear wheel is attached with a quick release. Unless the quick release on your bike is designed a little too short. In this case, it may not be possible to mount it. But we at Trailer Components have suitable solutions for this. We have numerous bicycle trailer couplings and adapters for bicycles with quick release. And also some components that are perfect for attaching Croozer bike trailers.
Option 3: thru axle
The situation is different if the rear wheel of your bike is attached with a thru axle, because then you need special bike trailer couplings and adapters for bikes with thru axles to mount your Croozer bike trailer. This is because it is not possible to attach the universal Croozer bike trailer coupling included in the scope of delivery in this case. This is because the thru axle is too large. This means that the universal coupling/adapter does not fit through the hole. So that you can still connect your Croozer bike trailer securely to your bike, we offer suitable, high-quality thru axles with an integrated Croozer bike trailer coupling. This allows you to simply replace the existing thru axle on your bike with one of our compatible components.
Good to know: Of course, you will not only find the right Croozer bike trailer coupling or a suitable adapter here, but also lots of other fastening components, for example:
- Adapter with quick-release axle for "Weber" couplings
- Couplings and adapters for "Qeridoo" brand bicycle trailers
- Bicycle trailer couplings and adapters for e-bikes
- And much more
