Air-filled rubber tires are what make this a jogging stroller rather than a pushchair with big wheels. Inflated tires flex against the ground and take the shock out of broken asphalt, gravel, and cement joints before it reaches the seat, in a way that solid plastic wheels never manage at pace. The rear pair measure 15.5 in and carry the braking system; the 11.5-in front wheel either locks straight for holding a line at running speed or unlocks to swivel a full 360 degrees for maneuvering in a tight space. The frame is metal and polyester, weighs 24.5 lbs, and stands 45 by 22 by 42 in open, folding quickly down to 23 by 16 by 34 inches. Seat capacity is 33 lbs, and the range covers six to thirty-six months. The seat reclines between 110 and 143 degrees, so a child sits up to watch the route or leans back to doze mid-run, and the canopy sets to six separate positions rather than the usual two, which lets the shade follow the sun through a long outing instead of being all the way open or all the way shut. A five-point safety harness adjusts to fit and keeps the child in place over uneven ground. The front tray detaches for lifting a child in, and there is a rear tray with cup holders for the adult. The handlebar is filled with soft sponge, which matters over distance when hands stay in one place. A large storage bag underneath carries the rest.
