Sized as a first pedal bike, this 12-in kids bike fits riders 31.5 to 41.3 in tall with a 16.5 to 18.5 in inseam, which covers most 3 and 4 year olds. The seat clamp flips open by hand, so raising the saddle between 17.5 and 19.5 in takes seconds in the driveway rather than a trip to the toolbox. Two brakes are wired in: a lever on the bar for the planned stop and a rear coaster brake for the reflex of back-pedaling. The bike ships mostly assembled, with the tool needed to finish it in the box.
