The BOB Revolution FLEX DUALLIE is the ideal on- and off-road jogging stroller, for outdoor enthusiasts and urbanites alike, keeping families active for the years to come. So whether you want a vigorous training session or a nice long walk with your two kids, the Revolution FLEX DUALLIE is the ideal stroller for larger families. This stroller is amazingly versatile. The front wheel swivels, which allows for easy maneuverability through parks, city streets and other tight spots, but also locks for added stability when jogging or taking on rough terrain. And the handlebar adjusts, offering 9 positions to provide a perfect fit for parents of different heights. The Revolution FLEX DUALLIE boasts an ultra-smooth ride for your little adventurers. The state-of-the-art adjustable suspension system takes bumps in stride. Boardwalks, beaches and trails are no match for this stroller. Kids love the fully upright seating option and you only need one hand to adjust their seat angle. And keep all your supplies, gear and even a few toys in the extra-large cargo basket. When you're done for the day, fold the stroller in seconds and get going. Combine the Revolution FLEX DUALLIE with an infant car seat, like the BOB B-Safe 35 by Britax, to create the best travel system for your lifestyle. So go ahead - take your adventures to new heights with the BOB Revolution FLEX DUALLIE. BOB, the #1 jogging stroller.
