Built for performance, the all-terrain UPPAbaby Ridge jogger offers smart, adjustable features that keep both the pusher and passenger comfortable. It features an advanced responsive suspension system with variable coil springs for a smooth ride across terrains, no matter the child's weight. The never-flat 12′′ and 16′′ wheels have a deep tread for a comfy ride. And the reliable performance hand brake works well even when running downhill. At the push of a button, you can lock the front wheel when going from strolling to running. A visual indicator confirms the mode, while the adjustable tracker allows wheel alignment fine tuning. The 4-position handlebar (with a wrist strap) adjusts to four different locations for more precise pushing comfort. For rider's comfort, the deep padded seat keeps them safe and nestled. The recline swiftly switches from sightseeing to snoozing position. With a quick unzip, the canopy extends to deliver protective shade and block out nap time distractions. Peek in on your passenger through the top viewing window or leave the flap open for greater airflow. Keep smaller essentials within reach in a conveniently-placed zip pocket. You can also add a Bumper Bar (little ones love holding on to it). When you're done, the entire stroller folds easily and quickly with a simple push and twist of one hand. It also stands when folded. You can safely jog with baby approx. six to nine months, but consult your pediatrician first. You can also stroll with the Ridge from birth with the UPPAbaby Bassinet and adapters for the Aria or Mesa Infant Car Seats or select Maxi-Cosi, Nuna, Cybex, BeSafe and Joie infant car seats (all sold separately). The Ridge also accommodates a second older child with the Ridge PiggyBack Ride Along Board accessory (sold separately).
