Learning to balance comes before learning to pedal, and this pedal-free bike lets a child aged 2 to 5 push along with both feet on the ground. The saddle raises from 14.5 to 15.5 inches through a lock and release lever, matching an inseam of 20.5 to 24 inches as legs grow. A handlebar that turns a full 360 degrees means a tipped bike never twists the front end, and the added footrest gives somewhere to tuck the feet once a glide gets going. Twelve-inch EVA foam tires never need air, resist punctures and soak up bumps on wood floors, cement paths, grass and asphalt. The high carbon steel frame carries riders up to 66 pounds while the whole bike weighs 6.5 pounds, so a parent can hang it off one finger on the walk home. Overall footprint is 33.5 by 14.5 by 20 inches.
