Avenir

With two fast 20-inch wheels, a simple trailer arm, and the ability to haul two kids, Avenir's Sport Dual Trailer is perfect for parents on the go. It attaches to your bike with a foldable tow bar. And when you're off the bike, the Sport quickly transforms into a stroller with a 6-inch, quick-release wheel that can be mounted to swivel or stay fixed. In stroller mode, you get a foam-padded push bar with a hand brake and a safety wrist strap.
