We purchased our InStep Quick N EZ Bicyle Trailer (orange) for two reason: to get our 19 month old daughter out bicyling and also as a cargo trailer for weekend bike tours.Assembly was quick and easy. It basically comes in the form you break it back down to in order to travel: probably no more than 5 inches thick. The wheels snap easily into place and the upper roll bar pulls up and snaps into place. You snap the top on and velcro the bottom edges down. That was quick and easy. The hitch folds under the body for travel and swings out for use. The most challenging part of the set up is the bike connector. I use a road bike so I had to take out my rear skewer, add the connector and reassemble. That being done the trailer connects to bike fitting with a cotter pin and that's it.3 of my boys joined me with our daughter for a 10 mile bike trail ride at a local college. We squeezed 5 bikes and the trailer into our Suburban with the rear seat down. We had bought a toddler bike helmet, that Erin did not take to very well. I strapped her in the trailer in the middle position. She looked a little concerned so I made some faces at her until she smiled. We put on the helmet, but it pushed forward over her face when she leaned back because it hit the seat back so we just took it off.I was concerned about pulling a trailer behind my road bike, but it is a good clean connection and pull. We had a very fun ride together our first time out. Erin fell asleep for part of it of course. We got a lot of smiles as we rode by.I have a tour planned for sometime in July with one of my boys. We'll pack it with a tent and supplies for three days riding and two nights camping. We're looking forward to that.I highly recommend this trailer. It's a nice looking trailer, it sets up and breaks down very easily, it is very affordable and has mutiple uses. If you are not in the market for a $400 plus bike trailer this will be a good fit for you.
