The Helix Plus Upgrade Kit is our double stroller solution for families that already own an Orbit Baby Stroller Frame G2. This kit includes everything you need to transform your Stroller Frame G2 into a full-featured double stroller: a second SmartHub™ ring attachment, large stroller basket, ShadePad™ tablet pocket, and an extendable handlebar. Once installed, parents can stroll with all Orbit Baby seats (sold separately) in nearly all combinations, rotate seats for siblings to interact, convert from double to single mode on the fly, and easily navigate the narrow frame with our all-wheel patented QuadShock™ suspension.
