Thule hitch cup

Thule is a excessive-stop bike trailer producer that gives excessive-price ticket items. Therefore, the attachments and accessories are regularly high-priced as properly. At around $50, the thule hitch cup is the available alternative for thule proprietors.

In case you’re no longer sure what form of coupler attachment your bike trailer requires, just take a look at the person manual that came with the trailer or at the product description page.

Potential issues with disc brakes

Maximum bike trailer couplers are well matched with disc brake bikes right out of the container, except you have got a 12mm thru-axle. Mainly, burley and thule bike trailers might also require you to purchase an extra attachment so one can adapt the bike trailer hitch to work with a 12mm thru-axle.

Even though it is possible to attach any bike trailer coupler with any style of disc brakes (with the right adapter), it is crucial to observe that no longer all brands of bike trailers play properly with the almighty disc brake.

Burley trailers and thule trailers particularly are infamous for being incompatible with disc brakes.

If you have disc brakes, you need to read this guide on disc brakes and bike trailers.

What is the  most compatible bike trailer brand?

Bike Trailer Coupler Attachments: What Is It & Where Can I Get One?

Schwinn and instep bike trailers are the most like minded and problem-unfastened on the subject of attaching to any type of bike. I have attached my schwinn trailers to a cruiser, a mountain bike, a road bike, and a hybrid bike with none want to shop for additional attachments.

But, they’re now not totally “popular” as their product descriptions claim to be. That means, they may be regular in that they could connect to all styles of bikes (disc brakes, short-release, and many others.), but they can not attach to all manufacturers of bike trailers.

Regrettably, no one has found out how to make a sincerely regularly occurring coupler attachment device, but schwinn is getting pretty near! They made a big improve to their coupler gadget in 2016 that even works with thru-axle disc brake bikes.

Schwinn and instep bike trailers are below the identical organization, so that they use the precise equal coupler attachment  device.

What is the least compatible bike trailer brand?

Bike Trailer Coupler Attachments: What Is It & Where Can I Get One?

I have attached every primary bike trailer brand to many one-of-a-kind styles of bikes, together with a cruiser, mountain bike, hybrid bike, disc brake bike, and a road bike.

From my experience, the least compatible bike trailer brand to my exclusive bikes is thule.

It’s a near tie between thule and burley, however thule bike trailers are specially difficult to attach when you have a thru-axle disc brake bike.

Right here are reasons thule trailers are the least like minded:

1.The coupler hollow on thule trailers doesn’t match a thru-axle

Different coupler systems at the least have a large enough hole to in shape a 12mm thru-axle so that you can see if it will suit your bike, however thule’s coupler doesn’t even have a huge enough hollow to even try it.

As soon as i got my thule chariot pass, i was right away defeated thru the fact that i had to spend some other $60 on an adapter.

For this type of excessive-quit bike trailer producer, i’d wish that thule can at least produce a coupler which could deliver disc brake bikes a hazard by way of making a larger hollow. Even schwinn made a large coupler, and that they’re no longer nearly as high-end as thule is.

2.Thule trailers do now not include adapters

I understand it may look like a stretch to ask a employer to provide a thru-axle adapter to their customers. But with a high charge tag of over dollars a thousand for a number of its bike trailers, i don’t suppose  it’s unrealistic to provide the adapter within the container while a patron orders the product.

Of path, there are many forms of thru-axle sizes, in order to offer the appropriate adapter relying on the kind of bike the consumer has. For a high-stop business enterprise like thule, i don’t suppose it’s unreasonable. It simply looks like double-dipping to invite customers to buy a $60 adapter simply to attach the trailer to a bike.

The good information approximately thule is that they do offer greater variations of thru-axle adapters than any other agency, which you can check out in this put up.


If you’re thinking to simply make do with out getting a brand new coupler or make your personal, don’t do it!

Couplers are reasonably-priced and designed to make sure protection and safety at the same time as pulling the bike trailer. They’re simply one of those stuff you want so as to pull a bike trailer nicely, however from time to time they wreck or get misplaced.

I recognize, it’s a problem to get a brand new one, but for simply $10–$15, it’s well worth the investment to experience the achievement of pulling a bike trailer and treasured cargo with your own two legs.
