A 12-in kids bike shaped after a race motorcycle, carrying sporty panel graphics and a front number plate. Every dimension is scaled to a 3 to 4 year old: a 17.5-in saddle, a 16 in to 17 in inseam window, and riders 31.5 in to 41.3 in tall who sit upright rather than stretched over the bars. Only the handlebar adjusts, so reach can change without disturbing leg extension. The seat is rated to 143 lbs on a frame weighing 21 lbs Training wheels bolt on for the learning stretch, a closed guard covers the chain, and fenders block road spray.
