Adjustable handlebar and seat let this kids sport bicycle match changing rider height, so the 16-in model can fit children about 4-7 years old. A robust metal frame and a seat rated to 145 lbs provide solid support for everyday riding practice. Dual brake methods, with both a hand brake and a coaster brake, give kids more control when slowing or stopping. Crack-resistant, wear-resistant tires and anti-slip pedals help maintain traction on different surfaces. Two detachable training wheels help young riders keep balance, build confidence and transition when ready. Front and rear reflectors make the bike more visible in low-light conditions, and the included bell adds simple communication and fun. Pre-assembled parts reduce setup time so kids can start riding sooner.
