Wheels on this no-pedal balance bike glow as soon as they start rolling, which keeps a 12-month-old motivated to push along the hallway one more time. Steering locks at 45 degrees each way, a narrow enough arc that the front wheel cannot swing sideways far enough to drop the bike over. The handlebar sets at 15.5, 17, or 18.5 in and the saddle spans 10 to 11 in, so a single frame follows a rider all the way to 36 months. Corner covers are rounded to blunt knocks against furniture and doorframes.
