Pretty close to the factory model replacement. Missing a security pin that you insert into the trailer that the original unit had.

Thank you for your review. This item comes with a security pin attached to the replacement arm. Was it not the right pin for you?

Exactly what we were looking for. I was happy to be able to order just this part instead of the entire bike conversion kit. We have two chariot strollers and already have the bike conversion kit and two Axle Mount ezHitch (one on each of two bikes). We want to now tow both chariots at the same time (one with each bike) so only needed this additional hitch arm assembly, rather than a second entire kit, so this was perfect.


My bike was stolen with the Thule trailer hitch. After some looking on line I found ti at etraioer. The service was fast and I am very happy.


This part was exactly what we needed! It had to be modified only because we used it on an old Trek Rocket bicycle trailer but it works perfectly and e.trailer is an excellent company to do business with. Shipping was unbelievably fast and communication is very good as far as them letting you know when the order is received and when it was shipped. I will certainly do business with the company in the future! I never heard of this company before looking for this odd part for our trailer but I’m glad I stumbled accross them and will certainly be giving reference to anyone looking for this kind of business.


We lost a random part to our chariot in a move and didn't want to repurchase an entire kit, etrailer mailed us what we needed very quickly! I was back biking in no time. Wonderful fast and friendly service.


The part was exactly what I ordered and needed. The exceptional customer service is what made it great. It even arrived several dsys early making the expidited shipping well worth it. Thanks!


Great product, shipped super promptly. Only negative is that the box was nearly impossible to open and just had way too much packaging.


Fits perfect! Took about one minute to open the package and install it! Awesome, thanks!





Came just as pictured and faster than e xpected!



I have two trailer arms considering their only meant for 100 lbs...
I put it together with a toolbox that has six wheels underneath it that will never pop in the boxes lockable.
It makes a great for running errands and I have no problem carrying 250 lb payload based on mathematics only has about 80 lb of tongue weight.
But most people usually don't want to exceed 250 lb or around 200 lb especially going up a hill.
Therefore I usually use it for running errands at Home Depot or groceries and keep it usually around 200 lb and less.
