This 14-in girls bike pairs a rear doll seat and front basket with removable training wheels so kids ages 3 to 5 can ride and bring a favorite toy along. The metal frame arrives 85 percent pre-assembled, and a quick-release clamp raises the saddle from 19.5 to 21.5 in and the handlebar from 28 to 30 in as riders grow through the season. A front hand brake and a rear coaster brake give beginners two ways to slow down, while the fully enclosed chain guard keeps small hands, laces, and pant legs clear of the drivetrain.
