Safety and growth flexibility meet in this 16 in bicycle for riders ages four through seven. Front hand brake and rear coaster brake work with an enclosed chain guard to protect young cyclists. Training wheels build balance gradually while the handlebar adjusts from 31 to 32.5 in and saddle from 23 to 25.5 in. Five-layer rubber tires resist wear and punctures across asphalt, cement, and wood. Arrives 95 percent pre-assembled with tools included.
