For modern families on the go with two kids, the Double Helix Stroller Frame is Orbit Baby’s complete double stroller solution. With two SmartHub™ rings, parents now have the option to stroll with all Orbit Baby seats in nearly all combinations (infant car seat, stroller seat, bassinet, and toddler car seat – sold separately), making it perfect for siblings, twins, and growing families. Front-and-back rotating seats mean siblings can interact while strolling, and the swiveling double seat makes it easy to help your child get in and out. With just a couple of clicks, the frame converts on the fly into an uncompromised single stroller to fit your changing family life. The patented QuadShock™ suspension on all wheels gives the stroller a plush ride, and the narrow frame easily navigates through narrow doors and aisles. The stroller’s compact, nested fold fits in many different trunk spaces, and its smart storage options include a large under-stroller basket, two cupholders, a smartphone slot, and the ShadePad™ tablet pocket. It also features a custom black-finish aerospace-grade aluminum frame, 3-position telescoping handlebar, and hassle-free, no-pump tires. The Double Helix Stroller Frame is compatible with Orbit Baby’s stroller accessories, including the Sidekick™ Stroller Board (when in single mode) and Stroller Panniers. It meets CPSIA [HR4040] and ASTM F833-11.
