I love this trailer. I love that it is universal and can be used on almost any bike (as far as I can tell). I have used it with my 14 month old twins and they absolutely love it. It is small like other reviews have said. But, my twins are about 21 lbs each and they fit just fine with a bag thrown in with them at their feet. I am not sure how bigger kids would fit so you may have to try it out. There is also a small storage space in back. It was very easy to set up out of the box, which I was thrilled about (I am a single mom and hate putting things together). It is a great product for the price. Just what I was looking for.
