This bike trailer has been used 5-10 times. We bought it for our children but ended up moving to a hilly neighborhood where it wasn't convenient to use.
Below is the company's description for the item. Take your children along for the ride with the InStep Take 2 double tow-behind bike trailer carrier. 16-inch pneumatic tires with molded rims provide performance, safety, and timeless style. A five-point harness and safety flag ensure your riders are protected. The folding-frame design and quick-release wheel make for quick and easy assembly, storage, and transport. Designed to protect your child from the elements, a 2-in-1 canopy features both a bug screen and a weather shield with rear vent window. This tow-behind child carrier fits most bike styles, thanks to a versatile bike coupler. The maximum weight limit is 80 pounds (two 40-pound children) with an additional 12 pounds in the rear-seat storage area.
