How To Attach Bike Trailer Without Coupler Complete Guide

If you want to take your bike riding to the next level, attaching a bike trailer is a great way to do it. But if you don’t have a couple, don’t worry – there are still ways to attach a bike trailer without one. Here are some tips on how to attach bike trailer without coupler.

What’s The Purpose Of Searching For A Coupler Replacement?

Couplers are excellent for safely securing bike trailers to one another. However, two parts are sandwiched between the nut and the axle frame. To properly tighten a coupler on some bikes, there isn’t enough room for the coupler itself.

The answer is to look for alternatives that don’t take up a lot of space or have to be attached to other bike parts. You may think that I’ve installed the accessory on the wrong side of the bike, but that’s not the case.

Please know that this is not the situation. Kickstands can’t even be installed on some bike models because there isn’t enough room. The following alternatives to the traditional bike trailer coupler will come in handy if you’re having the same issue or don’t like the look of it.

How To Attach Bike Trailer Without Coupler?

The most common method of attaching a bike trailer is to use a coupler. However, there are a few other options. I’ve listed three products and the installation instructions below because making a custom mount at home isn’t practical for everyone.

1. Using A Bolt-on Hub

Instead of traditional bike trailer couplers, you can use the ODIER 12.2MM Steel Hitch on burly trailers. In terms of size and installation, it’s comparable to a bike trailer coupler.

Remove the rear wheel’s axle nut and washer first. Do the same thing on the other side.

Replace the washer with the hitch coupler because it has enough traction to hold the nut in place.

Adjust the hitch’s alignment to your liking now. Once you align the toolbar and insert the pin from its top, tighten the rear axle nut.

Finally, attach the safety strap to the tow bar by running it through the bike frame and securing it.

2. Chain Stay Frame Mount

Using the previous alternative with all types of trailers and mountain bikes is impossible. The VORCOOL Bike Trailer Hitch is a universal mounting kit for this very reason. Any bicycle can use it because it is attached to its frame. Take a look at this.

It is a sturdy steel-built piece with a simple-to-install design that requires no tools. This bike trailer would be ideal for hauling luggage, children, or even pets.

ChainStay mount frame method

First, attach the v-shaped portion of the hitch to the chain stay frame.

The hitch has a large knob, which you’ve already noticed. Tighten it by rotating it counterclockwise.

With two holes on each end of the attachment kit, you can connect it to your phone when you’ve put it in one end of the bike trailer and put it in the top clip.

Finally, secure the frame with the safety strap by clipping and strapping it through.

3. Seat Post Mount

Check out bike seat post mount hitches if you don’t like the axle options for attaching the trailer. For your consideration, I present the following three possibilities.

Bicycle trailer hitch with a zinc coating from Ventura and a quick hitch from Travoy.

The first two fall within a reasonable price range, whereas the third one does. However, the Travoy hitch can be installed without using any tools. Installing any one of these takes no more than a few minutes. To tow a trailer, all you need is to attach a hitch to the seat post.

There are no compatibility issues, which is a huge plus. Whatever the diameter of the seat post, you can use this hitch to bike trailer fastened securely in place.

Check Out Some DIY Alternatives

Do you consider yourself a do-it-yourselfer? If so, do you have the tools necessary to construct a hitch? In this case, you’ll be able to build a long-lasting and reliable component for a low price. Let’s take a look at how to do it and the required features.


  • Swivel caster wheels in every direction (buy the such a model that lets you remove the rear wheels)
  • Mount antenna poles to this cross bracket.

  • Step 1: Remove the caster’s axle bolt and remove the wheel before continuing. The wheel is unnecessary.
  • Step 2: Drill a hole in the cross bracket to accommodate the caster’s bolt.
  • Step 3: Using a self-locking nut, secure the caster to the bracket. You can use a grinder to remove the excess length from the bolt.
  • Step 4: Tighten the cross bracket bolts to secure the bike’s seat post hitch. The bike trailer bar is attached to the hitch using a simple pin with a safety lock. The caster here ensures that the wheel remains horizontal.

Which Types Of Bike Can Pull A Bike Trailer?

1. Quick-Release Bikes

The manufacturer mostly produces trailers for bikes with quick-release wheels. The axles on these bikes are stronger than those on normal motorcycles and can be removed fast.

Because of their wheels, the trailer may be repaired fast. If, on the other hand, your bike has dropouts in the shape of a hood and the coupler for the bike trailer does not fit, you will need to purchase spacers to allow the coupler to attach to the trailer.

2. Thru Axle Bikes

Through-axles are a common feature on today’s road bikes and mountain bikes. They travel quickly between the hubs and have a huge diameter. Especially with a burley trailer, the 12 mm-diameter thru-axles won’t fit into the bike trailer coupler. Therefore, an adaptor is something you’ll want to invest in.
