The Shyft DualRide is a versatile infant car seat and stroller combo with multiple modes: it’s an infant car seat with the base (stroller’s wheels remain attached to the base), it’s a stroller, it’s an infant carrier with the stroller wheels attached, and it’s an infant carrier without the stroller wheels attached. In your vehicle, you can install the Shyft DualRide with the base with either lower anchors or the vehicle seat belt. You can also install the Shyft DualRide without the base using the vehicle seat belt. Without the base, the Shyft DualRide can be installed with or without the stroller frame.
