Expose your child to the fun of the outdoors while protecting them from too much exposure to the sun with the Aosom 2-in-1 Child Bike Trailer and Stroller. This convenient convertible unit is constructed from a strong, lightweight aluminum frame that supports two children. A weather canopy protects your little ones from sun and rain, and a rear storage area provides extra room for carrying snacks, water, or any other small necessity. Smooth-rolling 20-inch aluminum quick-release wheels ride easily across uneven terrain to keep the ride comfortable wherever your bike takes you. Speaking of safety, the trailer/stroller has a sling seat with a five-point safety harness to keep your children secure. The hand-lock brake system on the rear wheel allows you to lock the jogging stroller while it's parked. Converting the unit from trailer to stroller and folding it up for storage each take only seconds, and no tools are needed. The conversion kit is included. Also, a bike hitch/coupler is included for connecting the trailer to the bike. It even fits a bike with quick-release wheels. Choose from a red, white, or blue model. One-year limited warranty.
