A quick release lever lets parents raise the saddle and handlebar of this 12 inch children's bike in seconds, so one bike can follow a child through several growth spurts. The sturdy metal frame carries a dual brake system that combines a hand brake with a rear coaster brake, and a fully enclosed chain guard shields the drivetrain during play. Two removable training wheels support early balance work, anti-slip grips and pedals improve control, and front, rear and wheel reflectors plus a bell add visibility on shared paths. The bike arrives largely pre-assembled and meets ASTM and CPSIA requirements.
