    • Works perfect
I needed a second coupler for my Retospec dog trailer. This is identical to the coupler supplied with the trailer. Easy to install and works well. Now the dog trailer can be pulled behind my bike or the wife's bike without switching the original coupler from bike to bike.

    • Easy mount and works great
I purchased this attachment for my husband’s bike so we can take turns towing the dog’s wagon. It fit his Trek verbe with no issues. It works like it’s supposed to.

Review Image by Clarmee
I have a need for speed. My wife does not have a need for speed. I bought this so that both of our bikes could pull the kid bike trailer, because just having it on her bike made family bike rides far too slow. I’ve had it for 6+ months and it’s worked great.

    • This is my hero
I now get to use my bike trailer!! We have been searching for a solution for over a year and this was it. It works great. Super easy to assemble, and there has been no issues.

    • Strong metal
I have a trailer for our dog and I wanted to be able to pull with either my or my wife's bike. Produce came quickly and installs in 3 minutes. I am happy with the purchase but seems expensive for what it is.
