I bought this to put on my women's mountain bike so that when my husband and I go out on rides together with the 2 kids, I could put my 2 year in this, and he could use the double bike cart for our older son (who isn't old enough for a bike but too big for one of these). I put it together myself and noticed after just step one (putting the bottom brackets on) that there was a problem... the bars are completely warped and crooked. Well, I take that back. It was only one that was warped. I continued to put it together, then took it out to put on the bike... and I just couldn't make it work. I may have my husband try again later, but I will probably just take it back and wait until I can afford something better.
