The Baby Jogger City Micro stroller is the most compact-folding made by Baby Jogger. The Baby Jogger City Micro stroller handles and steers as easily as any compact umbrella stroller of equal weight. It rides on EVA tires, with sealed ball bearings in the wheels to ensure no grit or dirt slows down your ride. Baby Jogger's patented quick-fold technology has been incorporated into the City Micro stroller and it collapses in a single easy step.
