Review: Such a great trailer! - We bought this rack for my son so he could carry yard tools and other items when he rides around the neighborhood looking for jobs. It attaches very easily and is very durable. Great quality for the money we spent on it. It's fits all of his tools nicely
Review: Good, but the trailer tongue needs some work - The basic design works for me as I need a trailer that connects to the seat post instead of the rear axle, but there are two (2) issues that hold it back from five (5) stars, both related to how the trailer tongue connects to the trailer. 1. Because the bottom bolt connects to the body of the trailer, you need to remove it before you can detach the front rail and fold down the side rails to store the trailer. Understandable design choice, but it is inconvenient. 2. The top bolt is just long enough, which means it is too short as it can easily unscrew itself as the trailer bounces around, which happened to me when I was towing a five (5)-gallon jug of water. On top of that, the jug slipped to the back of the trailer, which caused it to tip backwards and bend the bottom bolt as the trailer stayed connected to the bike (strong connector), and the bottom bolt was impossible to remove and replace without a hammer or a grinder. For this, I would recommend a longer top bolt and a thicker bottom bolt (I will be getting a few replacement parts just in case this happens again). Also, a word of warning: Because the trailer tongue is so long and somewhat flexible (cannot really do much to fix that for a seat post connection), even if everything else is secure, the trailer can flip on its side. This seems to be less of a problem if you load heavier items toward the front of the trailer instead of the rear, but I need to test that some more.

## Questions & Answers

**Q: Should the double nut on the axle be tightened against the wheel hub?**
A: I'd say yes. For the trailer I received the wheel axles are just as wide as the spacing between the mounting brackets welded onto the frame of the cart. The brackets should be spaced closer together so that the insides of these brackets easily align with the 2 sets of double nuts. As it came spaced wider ( in my opinion way too wide) between the brackets makes it difficult to attach the conical nut and align the washer with the bent tab onto the end of the skewer which makes it more difficult to remove a tire to repair a flat. You have to over tighten the skewer nut and bow in the outside tubing in order to get the brackets to contact the nuts. This is likely to angle the brackets and make them no longer parallel, which is yet another problem. I decided to compromise and add 2-3 washers on each side between the double nuts and the insides of the brackets. I'll also likely bend/bow the outer tubing so the end tips of the axles extend a little beyond the outside edges of the axle mounting brackets.  This is a very poor design or they substituted a wheel with a smaller axle length. Without firmly contacting the side brackets you're just relying upon the spring tension of the tubing being bowed in to hold the wheels on....not on my trailer.

**Q: My scooter rack shaft has no room vertically. Can the clamp be turned sideways to attach to my rack behind the seat?**
A: "No 

We do offer couplers that could be used as another option to fit customer needs. Type ""A"" & ""B"" hitch tow attachments"

**Q: Can i pull this with a a scooter on the roads**
A: Yes you should be able to if you modify it to for your scooter however that being said please look up local/state laws might not be legal in your state. I wouldn't go no 50mph with it but a 25 to 35mph cruise speed should be fine have seen these on e-bikes and mini bikes and they go around that speed.

**Q: How long is the horizontal part of the arm that connects to the seat post? Distance from the seat post connection to where the arm bends down?**
A: It is 21 inches to the first bend.

### ⭐⭐⭐⭐⭐ Nice trailer.
*by C***N on August 1, 2020*

As noted by others the instructions are very terse. Assembly however is very straight forward, had it together in about 45 minutes including the "figuring it out" factor. Of note, the seat post on my mountain bike is thicker than the trailer hitch was meant for and it was somewhat difficult to get both bolts started because of the length of the bolts too short by a couple millimeters. Had to omit the lock washer on one bolt to have enough thread to get the other bolt started. The trailer tongue clears the bike rack perfectly so I can keep the saddle bags on the bike in addition to the trailer. Construction of all components is solid, it was well packaged, and the paint and finish is nice. Overall a very well thought out piece of equipment. Aired the tires to 30 lbs last night to let them stretch out a little before pumping up to the full 36 lb psi. This a.m. the tires were at 20 lbs psi. May need some inner tube stop leak, will see. Took it for first test run, couple of miles down the road with a small load and I hardly knew it was behind me. So far I'm REALLY liking this trailer. I plan on ham radio bike expeditions and fishing trips and this truly beats the heck out of stacked milk crates on the bike rack! Just have to remember to swing a little wider around turns and be careful on narrow paths. This will be my o-fish-all fishing and and ham radio field day main mode of transportation!
