Amazon.com Product Description:
A children's bike trailer is great when you're on the move, but what happens once you arrive at the grocery store? With a normal trailer you'd just park it outside, but with the Schwinn Mark III, you can convert it to a handy stroller and bring your kids inside. The Mark III sports a lightweight aluminum chassis that provides space for up to two children, along with a zip-down weather shield that protects them from rain, wind, and other inclement weather. More importantly, the trailer is designed for quick, tool-free conversion, with a universal trailer coupler that attaches to any bike and a flip-out front wheel and handlebar for the stroller. It's easy to use, fun, and versatile.

Perhaps the most significant feature, however, is the size of the front wheel (16 inches), which gives the Mark III enough stability to function as a jogging stroller in addition to a walking stroller. Other details include smooth-rolling, 20-inch rear wheels with a quick-release design for easy storage; a hideaway clear window; a dual harness system; outrigger wheel guards; and a screened canopy for ventilation. The Mark III measures 52.5 by 20 by 34.5 inches (W x H x D) in trailer form, offers a maximum weight limit of 100 pounds, and is backed by a five-year warranty.

Rating : - Fantastic!
We love this trailer! I can pull my kids (3yr and 9mo) in this no problem. I barely feel them behind me because it's so light weight. We knew when we bought this the buckles were going to be hard to undo, and we needed extra padding for them to sit on. The reviews were right, but once we figured out a good way for the buckles, and I just laid down a light blanket underneath for extra support, we were good to go.

It was really easy to put together, although the directions weren't very clear. But, I would definitely buy this trailer again, and would even pay more for it. It converts to a jogging stroller, and I love the bigger wheel in front. It's a lot lighter than my double stroller, which is what I was using for jogging before I bought this. Great product!
