What Our Gearhead(R) Experts Are Saying:"The adjustable suspension takes the edge off gravel paths and cracked sidewalks so the kids aren't getting rattled around on every bump. The stroller kit is already in the box, so the transition from bike ride to neighborhood walk takes about two minutes."The heat-treated aluminum frame keeps the Cub X light enough to hitch and unhitch without a second person, while the hard plastic base handles the kind of scrapes and puddles that would wear through a fabric floor. Each seat reclines independently across three positions, so one kid can nap while the other stays upright, and the 20-inch wheels with wide-tread tires give the trailer enough ground clearance to follow you off the pavement.
