Children's bicycles are specially designed bikes for young riders, typically ranging in size from 12 to 24 inches in wheel diameter. These bicycles are lightweight and feature adjustable seats to accommodate growing children. They often come with training wheels to help beginners maintain balance while learning to ride. Safety is a key consideration in children's bicycles, with many models equipped with features like hand brakes and reflectors. Popular brands, such as Schwinn and Trek, offer a variety of styles and colors to appeal to kids. Proper helmet use is also encouraged to ensure safety while riding.
