My wife purchased this for me as a Christmas gift to haul around our two dogs. We have a 25 pound Welsh Corgi and a 10 pound mini Dachshund.
What I like about it: Both dogs fit easily into the large trailer and enjoy riding in it. It has a large padded cushion covering the floor that appears to provide a comfortable ride. The trailer is attached to the bike with a bar that has a large spring that provides some shock absorption. The trailer looks good and all the zippers and connectors work as designed. The trailer folds up easily into an approximate 2' x 3' x 6" package with the wheels stored inside the trailer when folded.
Things I didn't like: First I'll say my issues were with initial assembly, and after I made some modifications I don't expect to have any more problems.
While reading reviews about the trailer before putting it on my "wish list", I noted that some people opened the trailer up and got their pets to go inside it before trying to take them for a ride. That made since to me so the morning I received it I opened it in the living room with the wheels off so the dogs could go in and out of it. The sides fold open and are held in place by a cross bar on the top back corner. A screw-in knob is used on each side to connect the cross bar to the side frames. The first problem I encountered in assembly was I couldn't get the knob on one side to thread in and tighten. I ended up having to drill out a larger hole in the side frame to get the two pieces to align correctly.
The next step of assembly involved mounting the wheel axle supports to each side of the frame. Simple enough with one bolt each, but on one side a plastic insert that holds the wheel in place was not pressed far enough into the axle support and the wheel would not lock into place. The plastic insert is drilled through at the bottom with a pin inserted which didn't allow the insert to be pressed in further. It this point I had a choice, call the company and request a replacement part or grind down about a 1/8" of the plastic insert to allow the axle to lock into place. I had the tools so I ground down the piece, but I shouldn't have had to do that. The wheel and axle now easily locks into place and I don't expect any further problems with that.
I then mounted the bar that connects the trailer to the bike. Once again, it was easy enough with one bolt. I then tried to remove the "pin" that attaches the trailer to the piece mounted to the bike. The two parts are shipped attached together with the pin and a wire clip. The pin should easily slide out and disconnect the two parts. Sadly the pin wouldn't move. I ended up having to remove the bar from the trailer, put the bar in a vise, and use a hammer to drive the pin out. Once I got the pin out I realized the problem. The piece that attaches to the bike is powder coated, which is great, but the coating had not been removed from the inside of the hole. That in turn made the pin stick when inserted in the hole. After drilling out the hole to remove the powder coating, I was able to easily insert and remove the pin. What really bothered me was the pin could have never easily fit into the hole and must have been pressed in. Why would somebody do that? Don't they know the two pieces are meant to be easily disassembled?
Like I said at the beginning, the trailer works well once assembled. But if someone that isn't mechanically inclined had ordered the trailer they would probably have had to wait for new parts or would have sent it back. Poor quality control at the factory knocked this trailer down two stars in the rating.
