Traditional couplers can become a headache when it wears out and gets loose. That is when we wonder how to attach bike trailer without coupler.

But finding a suitable alternative can take a lot of time. Fortunately, I have already gone through the research part and would love to share the info with you.

In this article, I have talked about 3 convenient substitutions along with their installation process. Without further ado, let’s get started.

Why Does One Look for A Coupler Alternative?

Couplers do a great job securely keeping trailers. But two pieces go in between the nut and axle frame. For some bike models, there is hardly enough space to install a coupler and tighten the screw properly.

The solution is to look for alternatives that don’t take much space or mount in other parts of the bike. You might be thinking that I have mistakenly tried to install the accessory on the drive side of the bike.

Let me assure you that it is not the case. Some bicycle models don’t have much room to even install kickstands. If you are facing the same problem or don’t like the design of a traditional coupler, the following substitutes will help you a lot.

How to Attach Bike Trailer Without Coupler?

Couplers are the most common and widely used solution for attaching a bike trailer. But there are some alternatives to it. As making a custom mount at home is not practical for some people, I have listed 3 products along with the installation process below.

1.  Using A Bolt-on Hub

For burley trailers, you can use ODIER 12.2MM Steel Hitch instead of traditional couplers. It is about the same size as a coupler and requires the same installation procedure.

  • Firstly, remove the axle nut and washer of the rear wheel. Do it for the right side.
  • Put the hitch replacing the washer as it has enough grip to keep the nut in place.
  • Now, adjust the alignment of the hitch as you see fit. Tighten the axle nut once you have lined up the toolbar and inserted the pin from its top.
  • Finally, run the safety strap through the frame and clip it into the tow bar.

2.  Chain Stay Frame Mount

The previous alternative is not perfect for all types of hitches or bikes. That is why I have listed VORCOOL Bike Trailer Hitch which is a universal mounting kit. It gets attached to the frame of the bike making it compatible with any bicycle. Let’s see how to mount it.

It is a durable steel-constructed piece with an easy-to-mount design that needs no tool. Whether your trailer is for carrying bags, kids, or pets, it would fit perfectly.

  • First of all, place the v-shaped part of the hitch on the chain stay frame.
  • You have already noticed that there is a large knob on the hitch. Turn it clockwise to tighten it.
  • On the other end of the attachment kit, there is a tube with two holes. After inserting one end of the trailer, put the clip from the top.
  • Finally, clip and strap the safety strap through the frame to make it secure.

3.  Seat Post Mount

Those who don’t like the axle mount options can check out the seat post mount hitches for attaching the trailer. Here, I have three options for your consideration.

  1. WeeRide Co-Pilot Spare Hitch
  2. Ventura Zinc Coated Bicycle Trailer Hitch
  3. Travoy Quick Hitch

The first two are budget-friendly options but the third one is a bit expensive. However, you won’t need tools to install the Travoy hitch. All three need very little effort to install. You just have to tighten a hitch to the seat post and attach the trailer to it.

The best part is that there are no compatibility issues. No matter what the diameter of the seat post is, you will be able to perfectly fit this kind of hitch.

Check Out Some DIY Alternatives

Are you a DIYer and have the necessary tools to make a hitch at home? If the answer is yes, you will be able to make a durable and reliable part spending only a few bucks. Let’s know the steps and necessary components to do it.


  • A full set of swivel caster (buy such model that lets you remove the wheel)
  • A cross bracket that is used to mount antenna poles
  • A self-locking nut


Step 1: Before starting, remove the axle bolt from the caster and take out its wheel. We won’t need the wheel.

Step 2: Take the cross bracket and make a hole so that the bolt of the caster can fit in.

Step 3: Now, attach the caster to the bracket using a self-locking nut. You can cut the excess length of the bolt with the help of a grinder.

Step 4: Finally, attach the hitch to the seat post of the bike tightening the bolts of the cross bracket. And install the trailer bar to the hitch using a simple pin with a safety lock. Here, the caster ensures a horizontal movement.

Final Words

Choosing the best bike trailers is not the only concern that we have. Because couplers are a big issue when it comes to safe and trouble-free attachment options. So, I spent hours searching for ways on how to attach bike trailer without coupler.
