Four wheel elements work together on this 12-in kids bike to help young riders build balance and confidence, including two removable training wheels and 12-in wheels suited to cement, asphalt or boardwalk surfaces. The adjustable saddle from 18.5 to 21 in and matching handlebar let the 35.5 x 19.5 x 26 in frame fit kids 31.5 to 41.3 in tall as they grow. A quick release lever lets adults change and secure the seat height easily. A dual braking system pairs a front handbrake with a rear coaster brake, giving children intuitive stopping options while they practice. A fully enclosed chain guard, anti-slip grips and pedals, plus front, rear and wheel reflectors help support safer riding for kids ages 3 to 4 years old up to 110 lbs.
