Four-wheeled stability helps young riders gain confidence on this kids bicycle, with two detachable training wheels that let children practice balancing before riding on two wheels. The blue and green metal frame uses non-slip pedals and an ergonomic seat to support up to 110 lbs. The saddle adjusts from 21 to 22 in so the bike can fit kids about 37.4 to 43.3 in tall. A dual brake system combines a handbrake with a coaster brake for controlled stops. The fully enclosed chain guard keeps feet and clothing away from moving parts. Front and rear reflectors and wheel reflectors improve visibility in low light. The 40 x 19.5 x 28 in overall size is easy to handle on sidewalks and paved paths, and a bike bell adds extra fun for every ride.
