The smallest size in this bike family, meant for a rider 31.5 in to 41.3 in tall taking a first turn at pedaling. A flip lever drops the saddle to 17.5 in for the cautious early attempts, then lifts it to 19.5 in once feet find the pedals reliably, covering a 16 in to 18 in inseam. Bolt-on training wheels come away the day balance clicks. Riding at this size stays close to home, so a closed guard seals the chain within a 19-lb frame that is rated to hold 110 lbs A fill-in number plate, thumb bell, and reflectors come fitted.
