A 14-in wheel puts this kids bike in reach of a 3 to 5 year old standing 37.4 to 43.3 in tall, with a saddle that sets between 21 and 22 in The brake levers use a short grab distance so small fingers can squeeze them fully, and back-pedaling triggers the coaster brake as a second way to stop. Removable training wheels bolt off in one session once balance clicks. Thickened rubber tires take on cracked sidewalks and packed dirt, an enclosed chain guard keeps pant legs out of the drivetrain, and reflectors plus a bell finish the build.
